SQL Server - Always On High Availability Group Setup
We have an Always On High Availability Group setup with three database servers — two on the same subnet and one on a different subnet. The application server interacts with these database servers through the AG listener. Currently, this setup is running with application version X, and we have received a new application version Y for upgrade/migration (which includes database changes). To perform the application update, please clarify the recommended approach: Should I remove the database from the Availability Group and point to the primary replica to continue with the application update? or Can I proceed with the application update while the Always On configuration remains active, pointing to the AG listener?
"ALTER DATABASE CURRENT SET ALLOW_SNAPSHOT_ISOLATION ON" does not finish for several hours
I have tried enabling snapshot isolation on several SQL Server instances (2017 and 2022 developer editions) in single user mode with the same huge DB (4 TB) but the command does not finish even after 6 hours... ALTER DATABASE CURRENT SET ALLOW_SNAPSHOT_ISOLATION ON Session is waiting on "ENABLE_VERSIONING" and I don't see any noticeable I/O activity on the Windows disk itself.
How Can a Company Receive Support from Microsoft for SQL Server Enterprise with Software Assurance?
Hello, I’m currently managing SQL Server under the following licensing agreement: SQL Server Enterprise Core Single Language License & Software Assurance Open Value | 2 Licenses | No Level | 1 Year | Acquired Year 1 | AP I’ve been informed that Software Assurance (SA) no longer includes technical support for SQL Server. Could you please confirm if this is correct? If our organization needs technical support from Microsoft for SQL Server, I would like to clarify the following: Is it mandatory to have a Unified Support contract or to purchase incidents via the Microsoft Services Hub in order to receive support? Regarding Services Hub, I’ve heard that support incidents must be purchased using a personal Microsoft account (MSA). If this is true, can this method be used to receive support for corporate environments? Thank you in advance.SSMS Dialog Box issue
Using SSMS 21.5.14, but I know this issue has existed in previous versions of SSMS. When opening a View in Design mode in SSMS, if the View contains a UNION, SSMS pops up a dialog box like the one below. The dialog box immediately hides behind the active SSMS window and sometimes you are not even aware that it has appeared. If I do notice it immediately, I am not able to click the OK button to clear it. This dialog box sits happily in the background and I can still move around the SSMS interface, however it does some odd things like ignoring certain keypresses when editing stored procedures or trying to make changes in a Query window. The only option is to exit SSMS completely and start again. When I do exit SSMS, I get the following message: Has anyone else experienced this and is there a way to prevent it happening? TIA!
SQL Server 2025 – Native JSON Size Limit?
Hi Guys, I am exploring SQL Server 2025 to store JSON documents using the native JSON data type. I have gone through several Microsoft SQL technical documents but couldn’t find the maximum size of the native JSON data type. I believe it hasn’t been officially published yet. Does anyone have any insights? Thanks, Tushar

SQL Version Upgrade 2017 to 2019 in an unclustered read-scale availability group
We need to upgrade our production SQL servers from SQL 2017 to 2019 (both are Ent. Edition). We have ~70 servers hosted in our DC. Each SQL Server instance consists of 2 VMs in a 2 node FCI, failing over at the beginning of and mid-month. They constitute the primary in a read-scale AG, utilized for offloading read heavy reporting. The secondary in the AG is a single server Iaas VMs hosted in Azure, 1 per FCI. The AGs are set to manual failover, asynchronous commit. The primary and secondary are not together in a WSFC. Because they are not bound in a WSFC we believe we should be able to update the secondary to SQL 2019, then perform a rolling upgrade on the 2 node primary, without first removing the secondary from the AG and afterward having to reseed the DBs in the AG. Each server hosts ~50 client DBs and we'd like to avoid having to reseed some 3000+ DBs. Most of what I've found online deals with clustererd AGs so any experience, advise, comment is most welcome.
Bug: "Invalid column name" after sp_recompile for valid column in custom data type
Hello, I was hoping to find a workaround for an issue I am having. I believe this is a bug in SQL Server (we are using SQL Server 2022) I have written a utility stored procedure for solving the gaps and islands problem, utility.GetTimeIslands, which returns the longest contiguous islands from the time islands passed into it. This procedure utilizes a custom datatype, utility.TimeIslandList, which is defined as CREATE TYPE utility.TimeIslandList AS TABLE ( ISLAND_ID BIGINT NOT NULL, KEY_1 BIGINT NOT NULL, KEY_2 BIGINT NOT NULL, KEY_3 BIGINT NOT NULL, START_DATE DATE NOT NULL, END_DATE DATE NOT NULL, PRIMARY KEY (ISLAND_ID) ); The call to utility.GetTimeIslands in PRC.LoadDeals is DECLARE Til utility.TimeIslandList; INSERT INTO Til SELECT STG_DEAL_SCHEDULE_ID, DEAL_ID, PRICE_ACCOUNT_SET_ID, PRICE_ITEM_ID, START_DATE, END_DATE FROM #DealSchedulePrep; INSERT #LatestTimeIslands EXEC utility.GetTimeIslands Til; If PRC.LoadDeals is called after a server reboot, or after EXEC sp_recompile 'utility.GetTimeIslands'; Is called, it throws the error "Msg 207, Level 16, State 1, Procedure utility.GetTimeIslands, Line 60 [Batch Start Line 8] Invalid column name 'KEY_3'." Line 60 corresponds to the first statement in utility.GetTimeIslands where the custom data type is referenced WITH ChangePoints AS ( SELECT KEY_1, KEY_2, KEY_3, START_DATE as X_DATE FROM Til UNION SELECT KEY_1, KEY_2, KEY_3, DATEADD(DD, CASE END_DATE WHEN '9999-12-31' THEN 0 ELSE 1 END, END_DATE) FROM Til ) ... However, if DECLARE Til utility.TimeIslandList; EXEC utility.GetTimeIslands Til; Is called prior to calling PRC.LoadDeals, then PRC.LoadDeals does not throw the error. And PRC.LoadDeals will execute successfully until utility.GetTimeIslands is recompiled. Another interesting twist is that adding those lines to PRC.LoadDeals, prior to the actual call, does not help. It throws the same error on the empty call, if the empty call is made inside the stored procedure before the empty call is made outside the stored procedure. For that matter, once any call is made to utility.GetTimeIslands outside the stored procedure, calls made to it inside the stored procedure will work. Has anyone ever seen anything like this? If so, is there a solution outside of making the GetTimeIslands empty call after each server restart? Does anyone have a guess as to why the error message calls out KEY_3 specifically?
