Feature Proposal: Ability to Exclude a column/subset of Columns in Select.
Summary I would like to propose a new T-SQL feature that allows developers to select all columns from a table while explicitly excluding a small subset of columns. Currently, when a table contains many columns and only one or two need to be omitted, developers are forced to mention every remaining column manually in the "Select" SQL. This leads to verbose queries, reduced maintainability, and a higher chance of mistakes when the schema evolves. Motivation Consider a table with 20 or more columns. Current approach, SELECT EmployeeId, FirstName, LastName, Department, Designation, Email, PhoneNumber, DateOfBirth, Address, City, State, Country, PostalCode, ManagerId, JoiningDate, LastModifiedDate, Status, IsActive, CreatedDate FROM Employees; If the intention is simply to exclude a single sensitive column such as Salary, the query becomes unnecessarily long. A more concise alternative could be: SELECT * FROM Employees EXCLUDE (Salary); The engine would expand * internally and remove the specified columns before execution. Benefits 1. Reduces boilerplate code. 2. Improves readability for wide tables. 3. Makes queries easier to maintain as schemas evolve. 4. Reduces the likelihood of accidentally omitting newly added columns. 5. Makes it simpler to exclude sensitive or internal-use columns from result sets. Expected Behavior Single column exclusion SELECT * FROM Employees EXCLUDE (Salary); Returns all columns except Salary. Multiple column exclusion SELECT * FROM Employees EXCLUDE (Salary, PasswordHash); Returns all columns except Salary and PasswordHash. Suggested Validation Rules 1. Every excluded column must exist in the projected result set. If an excluded column does not exist, compilation should fail with an appropriate error. 2. Duplicate column names in the exclusion list should either: be ignored, or produce a validation error. 3. If the exclusion list removes every projected column, the statement should fail. Example: SELECT * FROM Employees EXCLUDE (Employee, Name, Salary); If these are the only columns in the table, an error could be raised such as: The EXCLUDE clause cannot eliminate all columns from the SELECT list. Returning a zero-column result set would likely be confusing and less useful. Additional Considerations This syntax could also be valuable when selecting from joins, views, or derived tables, where developers frequently want "everything except a few fields." Closing Thoughts I believe this would be a practical quality-of-life enhancement for T-SQL that addresses a common developer pain point while remaining simple to understand and implement. It would reduce repetitive code and improve maintainability without affecting existing queries.

Today, we are excited to announce the preview of multiparty analytics feature of Azure Confidential Clean Rooms, a fully managed service that allows customers and their partners to securely analyze privacy-sensitive datasets from multiple parties. It uses confidential compute enabled Apache Spark-based big-data analytics (Spark SQL) which helps protect their raw data from other collaborators and from the Azure operator by performing computations in a Trusted Execution Environment (TEE). Privacy-sensitive datasets include personally identifiable information (PII), protected health information (PHI) and cryptographic secrets. Organizations across industries are increasingly looking to supplement their data with data from business partners, to build a complete view of their business. For example, brands, publishers, and their partners need to collaborate using datasets containing Intellectual Property (IP) to improve the relevance of their campaigns. Confidential data clean rooms help solve this challenge by enabling organizations to share and analyze granular datasets in a secure environment that helps prevent raw data exfiltration—protecting intellectual property, preserving customer privacy, and addressing concerns around regulatory compliance. You can sign up for the preview here Key Features Fully Managed: Azure takes care of the infrastructure provisioning and scaling with no user intervention. This significantly reduces your onboarding effort allowing you to focus on the queries and insights, not on infra management. Confidential Spark SQL: Spark SQL allows you to query large datasets and run complex queries in a distributed computing environment. In the confidential computing enabled version, the Spark driver and executors are fully attested policy-governed enclaves running as virtual nodes on confidential Azure Container Instances (ACI) which helps prevent exfiltration of collaborators’ data during query execution. Governance: Helps manage membership to cleanrooms, enables and verifies approval for queries from relevant collaborators before executing them and verifies consent to access sensitive collaborator data. It also helps generate tamper-resistant audit trails containing salient clean room events. This is made possible with the help of an implementation of the Confidential Consortium Framework (CCF). Telemetry: Throughout every clean-room run, detailed logs are streamed out in real time to monitor performance, troubleshoot issues, and keep the analytics healthy — all without ever exposing the collaborators’ data at any time. Verifiable trust: Cryptographic remote attestation viz. full attestation based on confidential hardware reports allows independent verification of the TEE along with along with all components that are part of it, without just trusting the cloud provider, before sensitive data and decryption keys are made available to the TEE Open-source containers: All Microsoft provided cleanroom containers and sidecars are open-sourced here and can be verified for provenance and integrity guarantees using GitHub artifact attestation Use Cases Multi-party confidential big-data analytics unlocks value in scenarios where data sensitivity, regulatory pressure, or competitive concerns previously blocked collaboration. These are some early scenarios that can benefit from this. Media & Advertising Collaboration of advertiser CRM data with publisher data for audience targeting and segment activation. Collaboration of audience data with measurement partners for measurement and attribution. Banking & Finance Collaboration between banks and insurance firms to upsell relevant products to existing bank customers without sharing raw data from either side Collaboration with retailers to generate customized offers for bank customers, without exposing either party’s underlying data. Government & Public Sector Secure collaboration of data across government departments to deliver better citizen welfare outcomes. Secure collaboration between government and private enterprises on shared-interest workloads such as traffic monitoring and weather systems. Healthcare Enable healthcare firms — including biopharma organizations — to combine their data with third-party institutions to accelerate clinical development, like identifying eligible participants for a clinical trial, without exposing underlying patient data. Combine patient datasets across hospitals to study disease patterns or outcomes without exposing sensitive protected health information. "A higher standard for protecting user privacy and trust, the phase-out of third-party cookies, and global regulations demand more sophisticated data collaboration tools to support advertising marketplaces. Azure Confidential Cleanrooms (ACCR) provides a secure, feature-rich, and flexible foundation to implement privacy-preserving functions and enable insights without sharing privacy-sensitive data outside of organization boundaries. Built on the Azure Confidential Compute (ACC) platform and offering cohesion with Azure's diverse set of services, ACCR offers the attestation, audit, fine-grained access control, and verifiable trust tools required for secure and privacy-safe data collaboration in today's world." — Andrei Mackenzie, Engineering Manager, Microsoft AI "Azure Confidential Clean Rooms enabled our team to evaluate how clean room capabilities can support secure, governed data collaboration at scale. Through the Proof-of-Concept (PoC), we explored how privacy-preserving workflows, trusted access controls, and scalable compute can create a stronger foundation for responsibly leveraging first-party data. This helps reduce operational friction while supporting business growth, improving customer engagement, and enabling more relevant customer experiences." — Nic Dregne, Director, Microsoft AdTech Engineering Beyond Spark SQL Realizing other multi-party scenarios like custom analytics, ML training and inferencing on Azure Confidential Clean Rooms is in our roadmap.

I was working with a customer recently who had a somewhat unusual situation, unusual in that I have become accustomed to most government customers having an Express Route or site-to-site VPN connection to connect their on-premises network to their Azure environment. However, this customer had a need to connect to an on-premises SQL instance via the on-premises data gateway (OPDG). The OPDG is installed as a Windows service on a machine inside the on-premises network and, when registered in Azure, allows Azure resources to connect to services on premises (more here). I did not have any direct experience with this tool but worked with the customer to get it installed on their network, which included getting it to work with their proxy (thanks to the larger Microsoft team for the assist and thanks to the customer for their patience figuring this out). We got the gateway registered in Azure and were ready to test it out. The customer is using Logic Apps and the SQL Connector to connect back to their on-premises SQL instance. The initial attempt to connect to SQL using SQL credentials was successful (Yay!!!) but the customer wanted to use Windows Authentication (which is a best practice). However, when trying to establish the connection with Windows Authentication, they were getting the error "status 401 - Credentials are missing or not valid...The credentials provided for the SQL source are invalid." Doing a little sleuthing in the Security logs on the SQL server, we could see that the authentication attempt being made, but with null credentials. Of course! We're passing our Windows credentials to the OPDG, but we haven't configured the gateway service account with delegation permissions to pass them on to SQL! To configure the on-premises data gateway account for delegation, do the following: Create a Service Principal Name (SPN) using the setspn command line tool for the OPDG service account: setspn -S gateway\gatewayMachineName domainname\gatewaySvcAcctName Open Active Directory Users and Computers (ADUC) and locate the OPDG service account Open the Delegation tab and select "Trust this user for delegation to specified services only" and "Use Kerberos Only" then add the services for which you want the OPDG to have delegation, e.g. SQL Server. Once this was done, we could create the Logic Apps SQL Connection successfully. A good check is to see if you can enumerate the list of tables in the database to which you are querying. As it turns out, there is fairly good documentation on this topic under the Power BI documentation, but searching for this under the context of Logic Apps didn't yield much success! In any case, I hope this helps someone else in the future!
Unable to install SQL Server 2022 Express (installer glitch + SSMS error)
Hi, I recently purchased a new Lenovo laptop, and I am trying to install Microsoft SQL Server 2022 Express along with SSMS. SSMS installed successfully, but SQL Server installation fails, and sometimes the installer UI glitches or does not load properly. Because of this, I am getting connection errors in SSMS like "server not found" and "error 40". I am not very familiar with technical troubleshooting. Can someone guide me step-by-step in a simple way to install SQL Server correctly? Thank you.Modern Database Protection: From Visibility to Threat Detection with Microsoft Defender for Cloud
Databases sit at the heart of modern businesses. They support everyday apps, reports and AI tools. For example, any time you engage a site that requires a username and password, there is a database at the back end that stores your login information. As organizations adopt multi-cloud and hybrid architectures, databases are generated all the time, creating database sprawl. As a result, tracking and managing every database, catching misconfigurations and vulnerabilities, knowing where sensitive information lives, all becomes increasingly difficult leaving a huge security gap. And because companies store their most valuable data, like your login information, credit card and social security numbers, in databases, databases are the main target for threat actors. Securing databases is no longer optional, yet getting started can feel daunting. Database security needs to address the gaps mentioned above – help organizations see their databases to help them monitor for misconfigurations and vulnerabilities, sensitive information and any suspicious activities that occur within the database that are indicative of an attack. Further, database security must meet customers where they are – in multi-cloud and hybrid environments. This five part blog series will introduce and explore database-specific security needs and how Defender for Cloud addresses the gaps through its deep visibility into your database estate, detection of misconfiguration, vulnerabilities and sensitive information, threat protection with alerts and Integrated security platform to manage it all. This blog, part one, will begin with an overview of today’s database infrastructure security needs. Then we will introduce Microsoft Defender for Cloud’s unique database protection capabilities to help address this gap. Modern Database Architectures and Their Security Implications Modern databases can be deployed in two main ways: on your own infrastructure or as a cloud service. In an on-premises or IaaS (Infrastructure as a Service) setup, you manage the underlying server or virtual machine. For example, running a SQL Server on a self-managed Windows server—whether in your data center or on a cloud VM in Azure or AWS—is an IaaS deployment (Microsoft Defender for Cloud refers to these as “SQL servers on machines”) that require server maintenance. The other approach is PaaS (Platform as a Service), where a cloud provider manages the host server for you. In a PaaS scenario, you simply use a hosted database service (such as Azure SQL Database, Azure SQL Managed Instance, Azure Database for PostgreSQL, or Amazon RDS) without worrying about the operating system or server maintenance. In either case, you need to secure both the database host (the server or VM) and the database itself (the data and database engine). It’s also important to distinguish between a database’s control plane and data plane. The control plane includes the external settings that govern your database environment—like network firewall rules or who can access the system. The data plane involves information and queries inside the database. An attacker might exploit a weak firewall setting on the control plane or use stolen credentials to run malicious queries on the data plane. To fully protect a database, you need visibility into both planes to catch suspicious behavior. Effective database protection must span both IaaS and PaaS environments and monitor both the control plane and data plane because they are common targets for threat actors. Security teams can then detect suspicious activity such as SQL injections, brute-force attempts, and lateral movement through your environment. A Unified Approach to Database Protection Built for Multicloud Modern database environments are fragmented across deployment models, database ownership, and teams. Databases run across IaaS and PaaS, span control and data planes, and in multiple clouds, yet protection is often pieced together from disconnected point solutions Microsoft Defender for Cloud is a cloud native application protection platform (CNAPP) solution that provides a unified, cloud-native approach to database protection—bringing together discovery, posture management, and threat detection across SQL (Iaas and Paas), open-source relational databases (OSS), and Cosmos DB databases. Defender for Cloud’s database protection uses both agent-based and agentless solutions to protect database resources on-premises, hybrid, multi-cloud and Azure. A lightweight agent-based solution is used for SQL servers on Azure virtual machines or virtual machines hosted outside Azure and allows for deeper inspection, while an agentless approach for managed databases stored in Azure or AWS RDS resources provide protection with seamless integration. Additionally, Defender for Cloud brings in other signals from the cloud environment, surfacing a secure score for security posture, an asset inventory, regulatory compliance, governance capabilities, and a cloud security graph that allows for proactive risk exploration. The value of database security in Defender for Cloud starts with pre and post breach visibility. Vulnerability assessment and data security posture management helps security admins understand their database security posture and, by following Defender for Cloud’s recommendations, security admins can harden their environment proactively. Vulnerability assessments scans surface remediation steps for configurations that do not follow industry’s best practices. These recommendations may include enabling encryption when data is at rest where applicable or database server should restrict public access ranges. Data security posture management in Defender for Cloud automatically helps security admins prioritize the riskiest databases by discovering sensitive data and surfacing related exposure and risk. When databases are associated with certain risks, Defender for Cloud will provide its findings in three ways: risk-based security recommendations, attack path analysis with Defender CSPM and the data and AI dashboard. The risk level is determined by other context related to the resource like, internet exposure or sensitive information. This way, Security admins will have a solid understanding of their database environment pre-breach and will have a prioritized list of resources to remediate based on risk or posture level. While we can do our best to harden the environment, breaches can still happen. Timely post-breach response is just as important. Threat detection capabilities within Defender for Cloud will identify anomalous activity in near real time so SOC analytes can take action to contain the attack immediately. Defender for Cloud monitors both the control and the data plane for any anomalous activity that indicates a threat, from brute force attack detections to access and query anomalies. To provide a unified security experience, Defender for Cloud natively integrates with the Microsoft Defender Portal. The Defender portal brings signals from Defender for Cloud to provide a single cloud-agnostic security experience, equipping security teams with tools like secure score for security posture, attack paths, and incidents and alerts. When anomalous activities occur in the environment, time is of the essence. Security teams must have context and tools to investigate a database resource, both in the control plan and the data plane, to remediate and mitigate future attacks quickly. Defender for Cloud and the Defender portal brings together a security ecosystem that allows SOC analysts to investigate, correlate activities and incidents with alerts, contain and respond accordingly. Take Action: Close the Database Blind Spot Today Modern database environments demand more than isolated controls or point solutions. As databases span hybrid and multiple clouds, security teams need a unified approach that delivers visibility, context, and actionable protection where the data lives. Microsoft Defender for Cloud provides organizations the visibility into all of your databases in a centralized Defender portal using its unique control and data plane findings so that security teams can identify misconfigurations. prioritize them based on cloud-context risk-based recommendations or proactively identify other attack scenarios using the attack path analysis while SOC analysts can investigate alerts and act quickly. Follow this story for part two. We’ll go into Defender for Cloud’s unique visibility into database resources to find misconfiguration gaps, sensitive information exposure, and contextual risks that may exist in your environment.
