sql server 2019 how to reverse engineer a View using VS or Visio
Hi, I am trying to trace back, and document the lineage of a series of Views that have been created in SQL Server 2019 over many years. Many of the views are quite complex and are Views built or several other Views, Tables and functions. I need to unpick all of the dependencies and logic that has been used in creating these views. I tried to use both Visio and Visual Studios 'Reverse Engineer' tools to do this, but this is not supported for SQL Server 2019 or later. When I connect my database to Visio and select the server and have the connection authenticated, the dialogue box greys out the Views checkbox. I have been told that Visio does not support reverse engineering for SQL Server 2019 or newer. The correct ODBC driver is installed, and I am working with a supported version of Visio (Visio Plan 2) and Visio 2505. Is anyone aware of a workaround to this, and how I might use either Visio and VS to reverse engineer my 50+ views and find all their dependencies and calculations, outputting these in a diagrams that I can give to the engineers to easily understand and unpick? Otherwise, this will take me weeks to do. My company is not keen on using any Third party tools that we would need to install on the server, as these could cause a security issue, but any suggestions of anything that would be light touch would be most welcome. Any help would be much appreciated. Thanks!
How does GitHub Copilot in SSMS 22 handle database context collection before generating a response?
Hello, I am trying to better understand the internal workflow of GitHub Copilot in SSMS 22, especially for database-specific questions. From the product descriptions, it seems that Copilot can use the context of the currently connected database, such as schema, tables, columns, and possibly other metadata, when answering questions or generating T-SQL. However, I could not find clear official documentation about the actual sequence of operations. My main questions are: Before generating a response, does Copilot first collect database context/metadata from the active connection and then send that context to the LLM as grounding information? Or does it first use the LLM to interpret the user’s request, decide what information is needed, and then retrieve database metadata before generating the final answer? In some explanations, I have seen the phrase "Core SQL Copilot Infrastructure", but I cannot find any official documentation for that term. Is this an official component name? If so, what does it specifically refer to in the SSMS Copilot architecture? When Copilot answers schema-related or data-related questions, what information is retrieved automatically from the connected database, and is any SQL executed as part of that process? Is there any official architectural documentation that explains: context collection, prompt grounding, LLM invocation order, and whether query execution can occur before the final response is generated? I am asking because I want to understand the feature from both an architecture and data governance/security perspective. Any clarification from the product team or documentation links would be greatly appreciated. Thank you.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.
Kerberos double hop delegation on SQL Linked Server fails on AG listener after RC4 disablement
Environment 3 Node- SQL Server 2022 with Availability Group Windows Server 2022 - Linked Server configured with Kerberos delegation (double-hop scenario) - RC4 encryption recently disabled via GPO The Problem After disabling RC4 in the domain (not sure of this root cause), Kerberos delegation through a Linked Server stopped working — but only when connecting via the **AG listener name**. Connecting via the **node name** works fine. I try to migrate my service account to gMSA and I've recreate all SPN and all delegation for the new account, but the issue is the same: Authentication works if the linked server us the node name, if it use the Listener AG name the connection fail with ------------------------------ Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'.

Any guidance appreciated. Thanks.
Cannot connect Azure OpenAI Embeddings model to SQL Server 2025
On SQL Server 2025, I am trying to vectorize a table. To set up the ability for SQL Server 2025 to communicate with Azure OpenAI embeddings model, I first created a master key for encryption. CREATE MASTER KEY ENCRYPTION BY PASSWORD = 'Secret'; GO Then I set up a database scoped credential. CREATE DATABASE SCOPED CREDENTIAL [MyAzureOpenAICredential] WITH IDENTITY = 'HTTPEndpointHeaders', SECRET = '{"api-key":"secret"}'; Then I created an external model. CREATE EXTERNAL MODEL AzureOpenAIEmbeddingsModel WITH ( LOCATION = 'https://{secret}-eastus2.cognitiveservices.azure.com/openai/deployments/text-embedding-3-small/embeddings?api-version=2023-05-15', API_FORMAT = 'Azure OpenAI', MODEL_TYPE = EMBEDDINGS, MODEL = 'text-embedding-3-small', CREDENTIAL = [MyAzureOpenAICredential] ); However, when I run this simple script: DECLARE @text NVARCHAR(MAX) = N'SQL Server 2025 enables AI-powered applications'; DECLARE @embedding VECTOR(1536) = AI_GENERATE_EMBEDDINGS(@text USE MODEL AzureOpenAIEmbeddingsModel); I get this error. The database scoped credential 'MyAzureOpenAICredential' cannot be used to invoke an external rest endpoint. I have read through https://learn.microsoft.com/en-us/training/modules/build-ai-solutions-sql-server/4-integrate-ai-models pertaining to this task. As well as SQL Server 2025 docs for creating a model. I have also read SQL Server 2025 docs for creating https://learn.microsoft.com/en-us/sql/t-sql/statements/create-database-scoped-credential-transact-sql?view=sql-server-ver17. I have not found any answers.
Migrate SQL 2016 to SQL 2022 - Detail Work Breadown Structre (WBS)
Hi, We’ve started a project to migrate from SQL Server 2016 to SQL Server 2022, and I’m currently preparing a detailed Work Breakdown Structure (WBS). Has anyone in this community gone through a similar migration and been willing to share their project WBS, either in .mpp or Excel format? Regards, Subhasish RoyFeature 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.
Windows server 2025 SQL patching cluster problem.
Dear Team, I have a problem when I am patching upgrade windows server 2025 with KB5091157. After patching is the clustering is not able to join back; it shows the error with credentials. The log error is "Cannot connect sqlxxxxxxx." you do not have administrative privileges on the cluster. Contact your network administrator to request access. Note: The server is not in a different VLAN network.
Some Questions About `log_send_rate`, `log_send_queue_size`, `redo_queue_size`, and `redo_rate`.
Hello, I've recently been trying to monitor the latency of the Available Group. Regarding logsend latency and redo latency, I hope to monitor them using the `log_send_queue_size` / `log_send_rate` and `redo_queue_size` / `redo_rate` metrics in the `dm_hadr_database_replica_states` DMV. However, in the process, I noticed that even in busy systems, `log_send_queue_size` and `log_send_rate` are often 0, whereas in idle systems, `redo_rate` is never 0. Could you please explain the specific definitions of `log_send_rate` and `redo_rate`? Why is `redo_rate` not zero when no data synchronization is taking place? In a system where data synchronization is occurring, `log_send_rate` and `log_send_queue_size` may be zero. My understanding is that log sends occur very quickly, while the monitoring granularity is not fine-grained enough—is that correct? Hope someone from the community comment on this.SQL Server 2022 Database Engine Crash During Startup on Intel Core Ultra 5 / Windows 11 25H2

SSRS reports not working
Hi Microsoft team, We are looking for tech support on an issue with SSRS reports that are used in one of our applications. The details of the issue are as foll: When Trying to access an SSRS ReportServer instance (either through the SOAP Service, or directly from the browser) does not work. There are Errors observed in the log files as well as the user interface . The error message is An error occurred within the report server database. This may be due to a connection failure, timeout or low disk condition within the database. The user interface fails to load Report as a result Attached are the SSRS log files from the last month from one of the servers. The last time reports were successfully accessed was on Friday, June 15th. Starting this Monday all functionality stopped working. This environment has 4 SSRS servers under an High Availability AGL. RSManagement log files indicate that the ReportServer schemas may be in an inconsistent state |FATAL|8|Database upgrade failed!! The database may now be in an inconsistent state. Further research indicates that this may be corrected by the following procedure… Stop SSRS services Backup and delete ReportServer and ReportServerTempDB databases Start the SSRS services Use the wizard to create a new ReportServer set of databases Stop the SSRS services Delete the new (empty ReportServer) database Restore the backup of the ReportServer (from step 2 - do not restore the temp database) Fix schema of ReportServer.dbo.Catalog.PropertyField and ReportServer.dbo.Segment.Content (change columns from ntext to nvarchar(max)) Start the SSRS services (Monitor the RSManagement log file) Verify Backout if fail: (Stop Services, Restore the databases, Restart Services) This may also include refreshing of encryption keys and removing servers from the AGL prior to this procedure Can you please help identify what could be a possible root cause for this issue, confirm if the steps listed below present a plausible solution, and advise on any additional triaging steps or corrective procedures? Thanks in AdvanceSQL 2025 Fabric Mirroring
We have setup fabric mirroring in SQL 2025 on top of a replicated subscriber using azure arc, this is just for a proof of concept, the mirroring seems to work but there is a microsoft document https://learn.microsoft.com/en-us/fabric/mirroring/sql-server-limitations#database-level-limitations advising CDC and replication is not supported in 2025 for fabric mirroring, We observed with CDC enabled it did not allow fabric mirroring to be configured, but with replication it still allowed, we noticed change feed doesnt seem to work as there was a latecy of atleast 30 secs to mirror data to fabric. Is this something to do with replication being enabled we dont know, we still havent tested a plain database (without replication and/or cdc enabled) Following details are shared to our BI team about the current situation in an email Current Observations When executing the following command on the source database: EXEC sp_help_change_feed; the engine returns: Change Feed or Fabric Link is not enabled on database 'ourdb'. Additionally: SELECT [name], is_data_lake_replication_enabled FROM sys.databases WHERE [name] = 'ourdb'; returns: 0 Based on these results, the SQL Server 2025 Change Feed engine does not appear to be enabled for the database under test. Mirroring Behavior Despite the Change Feed status indicating disabled, data continues to be synchronized successfully to Fabric. This suggests that Fabric Mirroring is currently obtaining changes through an alternative mechanism rather than through the native SQL Server 2025 Change Feed feature. We also observed an approximate latency of 30 seconds, even for single-row insert or update operations. Further clarification from Microsoft may be required to determine the exact mechanism being used and whether this behavior is expected when SQL Server Replication is present. Production Considerations While the functionality appears to work in a test environment, several questions remain regarding production suitability: If the native SQL Server 2025 Change Feed engine cannot be enabled alongside replication, it is unclear how Fabric guarantees change retention and recovery during periods of high transaction volume. Additional validation is required to determine whether transaction log truncation, checkpoints, or backup activity could affect Fabric's ability to capture all changes consistently. Fabric Mirroring may introduce additional background workload against the source database, resulting in increased read I/O and resource consumption on a server already processing replication activity. Conclusion At present, data is successfully reaching Fabric; however, the native SQL Server 2025 Change Feed functionality does not appear to be active. The key question requiring clarification is whether SQL Server Replication prevents or alters Change Feed operation, and whether the current mirroring behavior is a fully supported production configuration. Until this is confirmed, we should treat the current implementation as a successful proof of concept rather than confirmation of a supported production architecture. Next Step: test a plain database with some rapid data insertion mechanism to see if change feed kicks in to push data to fabric at near real time speed. --Can someone from the community comment on this.SQL Server FCI CSV storage flips multiple times into Online (No Access) state and eventually fails
Dear Team, I'm encountering an issue with our SQL Server multi‑instance failover cluster after applying the OS security patches and restarting the second node. Once the second node comes back online, the Cluster Shared Volume (CSV) briefly flips multiple times into Online (No Access) state and eventually fails.(we can make it online manually, but again flips and failed after sometime). To make the SQL cluster available, we either need to shut down the VM or revert the patch. Before the patching, all cluster roles and SQL instances were moved off the node, and the cluster appeared healthy. The issue only occurs after the reboot of the second node. (first node patched and restarted and everything working fine) OS : Windows Server 2025 Standard Patch tried: KB5075899 (February,2026 ) KB5078740 (March,2026) KB5082063 (April 2026 ) KB5087539 (May 2026) Could you please advise if there are any specific checks or steps we should follow during OS patching to prevent CSV access loss? Is it an issue with the patch or something else? Any insights or recommended actions would be really helpful to perform the security OS patch in the server Thanks you!
SQL Server 2025 Log Shipping Fails with Missing Assembly (sqllogship.exe) on Split-Drive Install
Hello, I am testing SQL Server 2025 in a lab environment and have encountered an issue with log shipping that appears to be related to assembly resolution. Environment: SQL Server 2025 (fresh install, both unattended and manual tested) Windows Server 2022 and Windows Server 2025 (issue occurs on both) SQL binaries installed on E:\ Default system drive is C:\ Issue: When log shipping runs (via SQL Agent job or manually invoking sqllogship.exe), it fails with the following error: Unhandled Exception: System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.SqlServer.ConnectionInfo, Version=17.100.0.0... Observed Behavior: sqllogship.exe is located at:E:\Program Files\Microsoft SQL Server\170\Tools\Binn\ The required assemblies (e.g., Microsoft.SqlServer.ConnectionInfo.dll) are installed at:C:\Program Files\Microsoft SQL Server\170\Shared\MDS5xSMO\ The sqllogship.exe.config file in SQL Server 2025 includes explicit codeBase entries using relative paths:..\..\Shared\MDS5xSMO\Microsoft.SqlServer.ConnectionInfo.dll Because of this, the application attempts to resolve assemblies at:E:\Program Files\Microsoft SQL Server\170\Shared\MDS5xSMO\which does not exist by default. Workaround: Manually copying the shared SMO directory from C: to E: resolves the issue: C:\Program Files\Microsoft SQL Server\170\Shared\MDS5xSMO → E:\Program Files\Microsoft SQL Server\170\Shared\MDS5xSMO After doing this, log shipping works as expected. Comparison with SQL Server 2022: SQL Server 2022 sqllogship.exe.config is empty It does not rely on explicit codeBase paths Log shipping works without requiring any manual file copies Question: Is this expected behavior in SQL Server 2025, or a potential issue with how sqllogship.exe resolves shared assemblies when SQL is installed on a non-system drive? Specifically: Should Shared\MDS5xSMO also be installed on the same drive as the SQL binaries? Or should sqllogship.exe.config be updated to use absolute paths instead of relative ones? Would appreciate any confirmation or guidance from others who may have encountered this. Thanks!Documentation contradictory
Hi, ALL, Page https://learn.microsoft.com/en-us/sql/t-sql/statements/create-database-transact-sql?view=sql-server-ver17&tabs=sqlpool states [quote] SIZE, MAXSIZE, and FILEGROWTH parameters can be set when a UNC path is specified for the file. [/quote] However later on that same page it states [quote] SIZE can't be specified when the os_file_name is specified as a UNC path. [/quote] I think those 2 sentences contradicts each other.....Failure to run SSMS
Hi, ALL, For sometime I had both MSVC 2010 and 2017 installed on my laptop. Recently I needed space and decided to remove the old version. Unfortunately I thin I killed one of the SSMS libraries, because while it successfully starts, trying to go to the "New Query" window, Im getting the error "Library not registered". The server itself operates just fine as I can connect to it. Is there anyway to make it work again? Than you.Extended Event with app_name doesn't work properly
