Ignite 2025: Advancing Azure Database for MySQL with Powerful New Capabilities
At Ignite 2025, we’re introducing a wave of powerful new capabilities for Azure Database for MySQL, designed to help organizations modernize, scale, and innovate faster than ever before. From enhanced high availability and seamless serverless integrations to AI-powered insights and greater flexibility for developers, these advancements reflect our commitment to delivering a resilient, intelligent data platform. Join us as we unveil what’s next for MySQL on Azure - and discover how industry leaders are already building the future with confidence. Enhanced Failover Performance with Dedicated SLB for High-Availability Servers We’re excited to announce the General Availability of Dedicated Standard Load Balancer (SLB) for HA-enabled servers in Azure Database for MySQL. This enhancement introduces a dedicated SLB to High Availability configurations for servers created with public access or private link. By managing the MySQL data traffic path, SLB eliminates the need for DNS updates during failover, significantly reducing failover time. Previously, failover relied on DNS changes, which caused delays due to DNS TTL (30 seconds) and client-side DNS caching. What’s new with GA: The FQDN consistently resolves to the SLB IP address before and after failover. Load-balancing rules automatically route traffic to the active node. Removes DNS cache dependency, delivering faster failovers. Note: This feature is not supported for servers using private access with VNet integration. Learn more Build serverless, event-driven apps at scale – now GA with Trigger Bindings for Azure Functions We’re excited to announce the General Availability of Azure Database for MySQL Trigger bindings for Azure Functions, completing the full suite of Input, Output, and Trigger capabilities. This feature lets you build real-time, event-driven applications by automatically invoking Azure Functions when MySQL table rows are created, updated, or deleted - eliminating custom polling and boilerplate code. With native support across multiple languages, developers can now deliver responsive, serverless solutions that scale effortlessly and accelerate innovation. Learn more Enable AI agents to query Azure Database for MySQL using Azure MCP Server We’re excited to announce that Azure MCP Server now supports Azure Database for MySQL, enabling AI agents to query and manage MySQL data using natural language through the open Model Context Protocol (MCP). Instead of writing SQL, you can simply ask questions like “Show the number of new users signed up in the last week in appdb.users grouped by day.”, all secured with Microsoft Entra authentication for enterprise-grade security. This integration delivers a unified, secure interface for building intelligent, context-aware workflows across Azure services - accelerating insights and automation. Learn more Greater networking flexibility with Custom Port Support Custom port support for Azure Database for MySQL is now generally available, giving organizations the flexibility to configure a custom port (between 25001 and 26000) during new server creation. This enhancement streamlines integration with legacy applications, supports strict network security policies, and helps avoid port conflicts in complex environments. Supported across all network configurations - including public access, private access, and Private Link - custom port provisioning ensures every new MySQL server can be tailored to your needs. The managed experience remains seamless, with all administrative capabilities and integrations working as before. Learn more Streamline migrations and compatibility with Lower Case Table Names support Azure Database for MySQL now supports configuring lower_case_table_names server parameter during initial server creation for MySQL 8.0 and above, ensuring seamless alignment with your organization’s naming conventions. This setting is automatically inherited for restores and replicas, and cannot be modified. Key Benefits: Simplifies migrations by aligning naming conventions and reducing complexity. Enhances compatibility with legacy systems that depend on case-insensitive table names. Minimizes support dependency, enabling faster and smoother onboarding. Learn more Unlock New Capabilities with Private Preview Features at Ignite 2025 We’re excited to announce that you can now explore two powerful capabilities in early access - Reader Endpoint for seamless read scaling and Server Rename for greater flexibility in server management. Scale reads effortlessly with Reader Endpoint (Private Preview) We’re excited to announce that the Reader Endpoint feature for Azure Database for MySQL is now ready for private preview. Reader Endpoint provides a dedicated read-only endpoint for read replicas, enabling automatic connection-based load balancing of read-only traffic across multiple replicas. This simplifies application architecture by offering a single endpoint for read operations, improving scalability and fault tolerance. Azure Database for MySQL supports up to 10 read replicas per primary server. By routing read-only traffic through the reader endpoint, application teams can efficiently manage connections and optimize performance without handling individual replica endpoints. Reader endpoints continuously monitor the health of replicas and automatically exclude any replica that exceeds the configured replication lag threshold or becomes unavailable. To enroll in the preview, please submit your details using this form. Limitations During Private Preview: Only performance-based routing is supported in this preview. Certain settings such as routing method and the option to attach new replicas to the reader endpoint can only be configured at creation time. Only one reader endpoint can be created per replica group. Including the primary server as a fallback for read traffic when no replicas are available is not supported in this preview. Get flexibility in server management with Server Rename (Private Preview) We’re excited to announce the Private Preview of Server Rename for Azure Database for MySQL. This feature lets you update the name of an existing MySQL server without recreating it, migrating data, or disrupting applications - making it easier to adopt clear, consistent naming. It provides a near zero-downtime path to a new hostname of the server. To enroll in the preview, please submit your details using this form. Limitations During Private Preview: Primary server with read replicas: Renaming a primary server that has read replicas keeps replication healthy. However, the SHOW SLAVE STATUS output on the replicas will still display the old primary server's name. This is a display inconsistency only and does not affect replication. Renaming is currently unsupported for servers using Customer Managed Key (CMK) encryption or Microsoft Entra Authentication (Entra Id).

Thank you for choosing Azure Database for MySQL!Preventing and recovering from accidental deletion of an Azure Database for MySQL flexible server
Accidental deletion of critical Azure resources, such as Azure Database for MySQL flexible servers, can disrupt operations. To help avoid such accidental deletions, you can use a couple of options, including Azure Resource Locks and Azure Policy. This post explains how to implement these mechanisms, and how to revive a dropped MySQL flexible server by using the Azure CLI.Custom Port Support in Azure Database for MySQL – Flexible Server is Now Generally Available
We are excited to announce that custom port support for Azure Database for MySQL – Flexible Server is now generally available (GA). This long-requested feature gives you greater flexibility to align MySQL server deployments with your network and security requirements. By default, MySQL uses TCP port 3306; with this GA release, you can configure a custom port (between 25001 and 26000) when creating a new Azure Database for MySQL flexible server. This enables easier integration with legacy applications, helps comply with strict network security policies, and avoids port conflicts in complex environments. What’s new in GA (vs. Public Preview): In the Public Preview (July 2025), custom ports were only supported for VNet-injected (private access) servers, with no support for public access or Private Link connectivity. Now, with GA, you can create custom-port servers in any network configuration – including both publicly accessible servers and those using Private Link (private endpoint) connectivity. In short, all new MySQL flexible servers can be created with a custom port, whether they are configured for public network access or deployed into a private virtual network. Feature Highlights Custom Port Range: Choose a port between 25001 and 26000 during server provisioning. (Only one custom port is supported per server.) This is in addition to the default MySQL port 3306, which remains available for use if needed. Supported Scenarios: Custom ports are fully supported for new server creation, point-in-time restore (including cross-port restores), read replica setup, and High Availability (HA) deployments. You can perform a restore or set up a replica even if the source and target servers use different ports, and you can enable HA on a server configured with a non-default port. Networking Flexibility: Supported on both public access and private access configurations. You can create servers with a custom port in public access mode (accessible via the internet with firewall rules) or in private access mode (injected into a VNet). Azure Private Link is also supported – meaning you can connect via a private endpoint to a MySQL server running on a custom port. This enhancement broadens the feature’s applicability beyond the preview’s limited scope, allowing usage in all network scenarios. Managed Experience: The custom port feature is built into the managed service experience. Aside from specifying a different port number for client connections, there is no change in how you manage or operate the MySQL flexible server – all administrative capabilities and integrations (backup, monitoring, etc.) work as they do with the default port. Current Limitations Be aware of a couple of limitations at GA: Port Immutable After Creation: You cannot change the server’s port after the server is created. If you need to use a different port, you will have to create a new server with that port. As a workaround, you can use Point-in-Time Restore (PITR) to quickly clone your database into a new server with the desired port (since cross-port restores are supported), rather than performing a full manual migration. Geo-Replication/Geo-Restore: Cross-region operations like geo-restore and geo-replication are not yet supported for servers using a custom port. In other words, you cannot perform a geo-restore of a backup from a custom-port server, and you cannot create cross-region read replicas on custom port servers at this time. These capabilities are on the roadmap but remain unsupported in the current release. Why Custom Ports? Many enterprise developers and DBAs have asked for custom port support to accommodate specialized network scenarios. For example, some organizations enforce strict firewall rules or use non-standard ports for databases to meet internal security compliance requirements. Others may have legacy applications or multi-database setups that require MySQL to run on a port other than 3306 to avoid conflicts. The custom port feature addresses these needs by allowing you to select a non-default port during server creation, while Azure continues to handle all the usual PaaS management tasks. In short, you get the flexibility of a custom network configuration without losing the benefits of a fully managed database service. Getting Started Using a custom port is straightforward. At GA, the Azure portal’s create experience is the way to set a custom port (support in CLI/PowerShell/ARM will come later). In the portal, when you create a new Azure Database for MySQL – Flexible Server, you’ll find an option to specify the “Database port.” Provide any value between 25001 and 26000 as the port number for your server. Once the server is deployed, client applications should connect using the <servername>.mysql.database.azure.com hostname and the port you chose, instead of the default 3306. All other connection settings (such as SSL enforcement and credentials) remain the same. Make sure to configure network access rules to allow traffic on your chosen port. For public access servers, this means updating the firewall rules or network security groups to permit the custom port. For private access or Private Link setups, ensure that your networking (NSGs, on-premises firewall rules, etc.) permits traffic on the custom port to reach the database. Learn More Custom port support is now GA and ready for production use, so we encourage you to try it out if your environment can benefit from it. For more details on Azure Database for MySQL – Flexible Server connectivity and custom ports, refer to the official documentation: Networking Overview - Azure Database for MySQL | Microsoft Learn We look forward to seeing how you use this new capability to tailor your MySQL deployments. With custom port support now generally available, Azure Database for MySQL – Flexible Server offers even more flexibility to meet your organizational policies and integration needs, all while delivering a fully managed experience.

We’re excited to announce that Azure Database for MySQL – Flexible Server now supports MySQL 8.4 in General Availability (GA). This means you can create new MySQL 8.4 servers on Azure fully supported for production workloads. MySQL 8.4 is a long-term supported release from the MySQL community, bringing the latest features and improvements while emphasizing stability. With Azure’s managed service, you get these new capabilities backed by Azure’s enterprise-grade reliability and support. In short, MySQL 8.4 GA opens the door for you to upgrade your databases and future-proof your MySQL environment on Azure. Why Upgrade to MySQL 8.4? Avoid End-of-Support Deadlines: If you’re running MySQL 5.7 or 8.0 on Azure, planning an upgrade is crucial. MySQL 5.7’s community support ended on October 31, 2023, and MySQL 8.0’s end-of-life is April 30, 2026. Azure’s standard support for these versions extends slightly beyond those dates (until March 31, 2026 for 5.7, and May 31, 2026 for 8.0). After those points, servers on 5.7 or 8.0 enter Extended Support, a paid support phase that provides critical fixes for up to three years (through 2029). Running your database in Extended Support means additional costs. Upgrading to MySQL 8.4 now ensures your database stays within standard support for years to come, sparing you the hassle of last-minute upgrades or extended support fees. Benefits of MySQL 8.4: MySQL 8.4 is essentially an evolution of 8.0, so it brings numerous performance enhancements, security patches, and new SQL features that have been introduced since 8.0. Because it’s an LTS release, MySQL 8.4 is designed for stability – making it an ideal target for enterprises. Most applications that work on MySQL 8.0 will be compatible with 8.4 with little to no changes, but with 8.4 you gain improvements in areas like replication, query optimization, and JSON handling (among others) that can boost your application’s efficiency. Moreover, by standardizing on 8.4, you align with the version that will receive updates well into the future. In summary, upgrading means better reliability, availability, and security now, and assured support longevity. Upgrading from MySQL 8.0 (In-Place Upgrade) For current Azure Database for MySQL 8.0 users, moving to 8.4 is straightforward, thanks to our in-place major version upgrade capability. You can upgrade your existing 8.0 server to 8.4 on the same server instance, without dumping and restoring data. Here’s how it works: Upgrade Availability: If you create a new MySQL 8.0 server today (post-GA), the option to upgrade to 8.4 is available immediately in the Azure portal or CLI. For existing 8.0 servers (those created before this GA release), the upgrade capability will become available after your next scheduled maintenance window. The September 2025 platform update is enabling this feature across all regions. Note: Azure will not auto-upgrade your server during that maintenance; it only enables the new version as an option. You remain in control of when to perform the major version upgrade. Performing the Upgrade: Once the feature is enabled for your server, you can initiate the upgrade via the Azure portal, Azure CLI, or PowerShell. The process involves a downtime (the server will be taken offline and restarted on MySQL 8.4), so plan to execute during a maintenance window or low-traffic period. We strongly recommend taking a backup or snapshot before upgrading, as a precaution. For a step-by-step guide and best practices (including how to minimize downtime by using read replicas for the upgrade), refer to the official Azure documentation on https://learn.microsoft.com/azure/mysql/flexible-server/how-to-upgrade. In most cases, upgrading from 8.0 to 8.4 is completed within several minutes. After upgrade, your server retains the same endpoints, configuration, and data – just running on the new MySQL 8.4 engine. Upgrading from MySQL 5.7 (Two-Step Path) Upgrading from MySQL 5.7 to 8.4 requires a two-step approach, since a direct jump is not supported: First upgrade 5.7 to 8.0: Azure MySQL Flexible Server supports in-place major upgrade from 5.7 to 8.0. This moves your server to a supported major version and is a necessary intermediate step (you cannot skip major versions in one go). MySQL 8.0 introduced some changes from 5.7 (for example, stricter SQL modes and a new default authentication plugin), so after upgrading to 8.0, test your application and fix any compatibility issues. Azure’s standard support for 5.7 runs until March 31, 2026, so you should aim to complete this step before then. Then upgrade 8.0 to 8.4: With your server now on 8.0, you can use the in-place upgrade to 8.4 as described above. All Azure 8.0 servers will have the 8.4 upgrade option by the end of the next maintenance cycle (after the feature rollout in September 2025). Plan to perform the 8.0 → 8.4 upgrade at a convenient time, ideally well before MySQL 8.0’s support winds down in 2026. This final step ensures you’re on the latest GA version and out of the legacy support cycle. Some customers may choose to migrate 5.7 to 8.4 by creating a new 8.4 server and importing data (using dump and restore or Azure Database Migration Service). This approach can be useful if you want to reorganize your environment or test in parallel. However, it will likely involve more downtime than the sequential in-place upgrades. Evaluate which method fits your needs – either way, now is the time to start, given that free support for 5.7 ends in less than two years. Support Timeline Summary and Next Steps To recap the support timelines and why upgrading matters: MySQL 5.7: Community EOL: Oct 31, 2023. Azure standard support until: March 31, 2026. After that, servers enter extended support (critical fixes only, with additional charges) until March 31, 2029. Action: Plan to upgrade off 5.7 before Q1 2026 to stay within standard support. MySQL 8.0: Community EOL: Apr 30, 2026. Azure standard support until: May 31, 2026. Extended support then runs to May 31, 2029. Action: Begin upgrading 8.0 instances to 8.4 in the coming months, rather than waiting until the last moment. The upgrade feature is available now (or after one maintenance cycle for older servers). MySQL 8.4: GA start: Sep 2025 (now). This is the recommended target for all MySQL deployments on Azure going forward. It will be fully supported on Azure well beyond 2026, receiving regular updates and improvements as part of the Azure service. Action: Deploy new databases on 8.4 and upgrade existing 5.7/8.0 databases to 8.4 when feasible, to benefit from the latest features and long-term support. Next Steps: Getting started with MySQL 8.4 on Azure is easy. You can create a new Azure Database for MySQL 8.4 server from the Azure Portal or via CLI today. For existing servers, review the https://learn.microsoft.com/azure/mysql/flexible-server/how-to-upgrade to choose your upgrade method (in-place with some downtime vs. replica method for minimal downtime) and schedule a time for the upgrade. By moving to Azure Database for MySQL 8.4, you’re investing in a more stable, performant, and future-proof foundation for your applications. We’re thrilled to see customers embrace MySQL 8.4, and we’re committed to making your upgrade process as smooth as possible. Upgrade with confidence, and leverage the power of MySQL 8.4 in Azure to drive your business forward!

While you can accomplish data integration in several ways, you can use Logic apps to move data to an Azure Database for MySQL flexible server and automate data integration tasks that you perform in response to API calls.Boost your MySQL apps: why enterprises are migrating MySQL databases to Azure
MySQL is one of the world’s most popular open-source databases, and for good reason. It’s cost-effective, scalable, and familiar to millions of developers. But if your enterprise is running MySQL on-premises, you might be missing out on huge benefits in cost savings, performance, and agility. Recent findings from an ESG Economic Validation report, commissioned by Microsoft, reveal just how advantageous it is to migrate on-premises MySQL databases to Azure’s fully managed database- as -a -service platform. Read the full MySQL report TL;DR – benefits of migrating to Azure Database for MySQL Managing data security, quality and privacy as well as general database management are among the most significant challenges facing developer teams. Some even report that database technology is evolving faster than they’re able to keep up with. Migrating to Azure’s fully managed service offloads these responsibilities so teams can focus fully on projects that move their business forward. Some benefits of moving from on premises to Azure Database for MySQL highlighted in the report include: 54% lower total cost of ownership 86% lower MySQL admin costs 25% increase in development velocity “Our developers can now focus on their core job: creating code. We now put out 8 releases per year compared to 2 when we were on premises. This gets features and fixes in the hands of our customers sooner.” Review the Azure Database for MySQL Economic Validation Infographic Zooming in – how fully managed open-source databases on Azure deliver economic wins for the enterprise More than 50% lower costs and total cost of ownership Azure’s fully managed MySQL service delivers the same (or better) database capabilities for almost half the cost. By one estimate, a company could save millions over a few years and even see an ROI above 90% from the migration when factoring in both cost savings and new revenue opportunities. These savings come from a few key areas: No more hardware and maintenance expenses: On-premises MySQL deployments require investing in servers, storage, networking gear – plus ongoing power, cooling, and data center space. Azure Database for MySQL eliminates those needs entirely. You don’t buy or maintain hardware; Microsoft handles the infrastructure. Drastically reduced admin overhead: Companies in the study reported an 86% reduction in the cost of MySQL administration after migrating to Azure. All the routine tasks—installing updates, patching OS and MySQL versions, tuning performance, taking backups, managing high availability—are handled by Azure as part of the service. Pay-as-you-go efficiency: On-premises setups often over-provision resources to handle peak loads, which wastes money during lulls. Azure can scale resources on-demand, so you’re never stuck paying for idle capacity. You can also use cost controls like burstable instances for dev/test, stop/start to pause servers, and reserved instances for discounts. Included extras: Many capabilities that would incur extra cost on-premises (or require separate licenses) are bundled into Azure Database for MySQL. For example, security features, monitoring and performance tuning tools, backup storage, and high availability options come built-in at no extra charge in Azure’s service tiers. Improved performance and scalability Beyond cost, Azure Database for MySQL helps your applications run faster and scale seamlessly to meet demand. In on-premises environments, you might need to tune configs, add hardware, or handle sharding as usage grows. Azure takes a lot of that burden away and offers cloud-scale performance out of the box: Better throughput: Azure’s managed MySQL runs on high-performance cloud infrastructure (with fast SSD storage, plenty of memory, and low-latency networking). Microsoft has also added capabilities like accelerated I/O logs and intelligent caching that improve MySQL’s throughput and response times compared to typical on-premises setups. Elastic scaling on demand: With Azure, scaling up a MySQL server is as simple as a configuration change. No new hardware is required. You can scale vertically (bigger machine) or horizontally (add read replicas) in minutes. Azure even supports autoscaling of IOPS and storage based on set thresholds. This flexibility means your database can handle traffic spikes or growth without manual intervention. No wasted capacity: On-premises, you often must deploy extra servers “just in case” future demand increases, and that hardware sits underutilized most of the time. Azure’s model avoids this waste. Enterprises reported that Azure’s ability to fine-tune resources helped them avoid overprovisioning and maintain a better price/performance mix. Reliable high performance at scale: Whether you have 10 users or 10 million, Azure’s global infrastructure can scale to meet your needs. One customer in the study found that after migrating, they could provide MySQL services 5× faster than when they were on-premises. Faster development cycles and greater developer productivity For developers, one of the biggest wins of moving MySQL to Azure is time back to innovate. When you no longer have to babysit your database infrastructure, you can focus on building features and improving your applications. The ESG report highlighted that companies saw significantly improved developer productivity and agility after migrating. Faster development: Organizations reported that their development cycles became 25% faster on average once on Azure. One customer shared that “our developers can now focus on their core job: creating code.” The customer went from shipping two software releases per year to eight releases per year after migrating to Azure. Elimination of toil: Azure’s fully managed platform lifts the burden of routine DB administration from your team. No more worrying about backups, failover, or OS patches. The service continuously applies best practices and optimizations automatically, so your team doesn’t have to. Teams can be more agile because they’re not bogged down by lengthy processes or constant maintenance. Faster time-to-market: ESG modeled that by releasing features earlier and more often, thanks to Azure MySQL, a mid-sized software company could realize an additional $15 million in revenue over three years by being first-to-market with new capabilities can capture customers and market share. Stronger security and high availability Running MySQL in Azure doesn’t just make life easier and cheaper. It also makes your databases more secure and resilient. Enterprises often struggle to keep up with patches, security threats, and high availability when managing databases on-premises. Azure Database for MySQL is hardened with enterprise-grade security and reliability features that can significantly reduce your risk. Fully managed security updates: In the ESG survey, nearly half of organizations (46%) said they needed outside expertise to help manage database platforms on-premises often because of the complexity of securing and tuning them. Azure takes care of patching the MySQL engine and underlying OS for you, ensuring you’re always on a supported, secure version. Enhanced data protection: By default, Azure Database for MySQL encrypts data at rest and in transit. It also offers network isolation options to lock down access to your database. Many customers found that after migrating, their security posture was stronger than before. They could easily implement role-based access control via Azure AD, set up threat detection alerts, and use Azure’s monitoring to audit activity with just a few clicks. High availability and disaster recovery built In: Azure Database for MySQL can be deployed with high availability configurations across availability zones. In case of an outage, it can switch to a standby replica usually in under 60 seconds, dramatically reducing downtime for your apps. Companies in the study experienced 70% less downtime incidents after moving to Azure. Compliance and governance: Azure Database for MySQL is compliant with a broad set of industry standards and certifications, easing the audit burden. Many organizations found that moving to Azure made it simpler to adhere to internal security policies and compliance standards because so many controls are built into the platform. Enterprise-ready MySQL is just a few clicks away Azure provides a hardened, enterprise-ready environment for MySQL that most companies would be hard-pressed to build on their own. By entrusting MySQL to Azure’s managed service, you benefit from Microsoft’s investments in security and infrastructure resiliency. The result is peace of mind: your data is safer, your databases are more stable, and your team has far fewer 3 AM incidents to deal with. Read the full report for more details about the quantified benefits and customer testimonials. If you’re ready to start your journey, check out our migration guides.

We’re thrilled to announce the general availability (GA) of Azure Database for MySQL Input and Output bindings for Azure Functions—a powerful way to build event-driven, serverless applications that seamlessly integrate with your MySQL databases. Key Capabilities With this GA release, your applications can use: Input bindings that allow your function to retrieve data from a MySQL database without writing any connection or query logic. Output bindings that allow your function to insert or update data in a MySQL table without writing explicit SQL commands. In addition you can use both the input and output bindings in the same function to read-modify-write data patterns. For example, retrieve a record, update a field, and write it back—all without managing connections or writing SQL. These bindings are fully supported for both in-process and isolated worker models, giving you flexibility in how you build and deploy your Azure Functions. How It Works Azure Functions bindings abstract away the boilerplate code required to connect to external services. With the MySQL Input and Output bindings, you can now declaratively connect your serverless functions to your Azure Database for MySQL database with minimal configuration. You can configure these bindings using attributes in C#, decorators in Python, or annotations in JavaScript/Java. The bindings use the MySql.Data.MySqlClient library under the hood and support Azure Database for MySQL Flexible Server. Getting Started To use the bindings, install the appropriate NuGet or npm package: # For isolated worker model (C#) dotnet add package Microsoft.Azure.Functions.Worker.Extensions.MySql # For in-process model (C#) dotnet add package Microsoft.Azure.WebJobs.Extensions.MySql Then, configure your function with a connection string and binding metadata. Full samples for all the supported programming frameworks are available in our github repository. Here is a sample C# in-process function example where you want to retrieve a user by ID, increment their login count, and save the updated record back to the MySQL database for lightweight data transformations, modifying status fields or updating counters and timestamps. public class User { public int Id { get; set; } public string Name { get; set; } public int LoginCount { get; set; } } public static class UpdateLoginCountFunction { [FunctionName("UpdateLoginCount")] public static async Task<IActionResult> Run( [HttpTrigger(AuthorizationLevel.Function, "post", Route = "user/{id}/login")] HttpRequest req, [MySql("SELECT * FROM users WHERE id = @id", CommandType = System.Data.CommandType.Text, Parameters = "@id={id}", ConnectionStringSetting = "MySqlConnectionString")] User user, [MySql("users", ConnectionStringSetting = "MySqlConnectionString")] IAsyncCollector<User> userCollector, ILogger log) { if (user == null) { return new NotFoundObjectResult("User not found."); } // Modify the user object user.LoginCount += 1; // Write the updated user back to the database await userCollector.AddAsync(user); return new OkObjectResult($"Login count updated to {user.LoginCount} for user {user. Name}."); } } Learn More Azure Functions MySQL Bindings Azure Functions Conclusion With input and output bindings for Azure Database for MySQL now generally available, building serverless apps on Azure with MySQL has never been simpler or more efficient.
