adding computed column to MS SQL
would like to check how to add a computed column with the following requirement Column value will be C-yyyyMMdd-0001 where date will be from the CreatedDate column in the same table. 0001 is an auto-incremental value based on when the record is inserted on the same day eg, the first record added on 23/08/2025, the computed column will be C-20250823-0001. As the table may already contain existing data, a SQL script may also be necessary to update this new column with the correct value.

Cannot Disable Named Pipes
I have an installation of SQL Server 2022. I have a named instance. When I set the port to a non default port, I cannot disable the named Pipes (SQL Server cannot start). When I change the port to the default port 1433, the named pipes can be disabled without any issue. Is this correct?
Always On Availability Group -- Disk resize on the secondary replica
Hi, We currently have a 2 node on Always ON Availability group with a cloud witness. Recently, we found the need to resize the data file disk. This 2 nodes are SQL Server on Azure VM. Find below our current situation 1st Resize on the secondary node (read-only) Resizing first on the secondary node - we noticed that the disk type changed from Basic to Dynamic mode and having seen some documentation on internet -- https://lokna.no/?p=1384 we thought of been cautious of having the disk in dynamic mode. As a result of the above, we did not proceed to resizing the the production until we are sure. Question Is it save to proceed with disk in dynamic mode? What if we proceed and the primary is still on Basic mode, is it OK to have the disk type of primary node as Basic and the disk type of secondary as Dynamic?

Hey everyone! We have a problem that is unsolvable for us. I hope that someone has already had this case or has enough expertise to find a solution for it. Introduction: We did a reallocation of de databasefiles (.mdf) and the logfiles (.ldf). We wanted to split all databasefiles to a datadrive and all logfiles to a logdrive. Apparently some days later one specific database reached the Suspect-mode: We were able to get the database back online through creating a new database with the existing logfile and databasefile. Apparently some of the tables are memory-optimized and no longer work. We have to delete these specific memory optimized tables, but we were not able to do that: We tried everything, even restoring the missing "memory optimized db" files: Dropping the mem_opt_filegroup first also fails (seems to happen because the mem_opt_filegroup is a restore from 3 months ago): As a side info, I am on a restore in an isolated environment. Thank you in advance for any support.
Combining names in SQL
I have a report I'm working on in power BI and I would like to combine Samantha Marshall who is now now Samantha Murphy. What is the query I should write? -->I tried the following with no luck Update [Table name] Set created_by = 'Samantha Murphy' where created_by = 'Samantha Marshall'TLS 1.2 support on SQL server 2014
We have SQL server 2014 (with sp3 installed) hosted on Windows Server 2012 R2. Recently our client application upgraded to use OpenSSL 3.0.8 and we are restricting to use TLSv1.2 & TLSv1.3 only. Now our client application is not able to connect to SQL server via ODBC driver 17/18. I tried enabling TLSv1.2 on SQL server 2014 including applying service pack3 (https://support.microsoft.com/en-us/topic/kb3135244-tls-1-2-support-for-microsoft-sql-server-e4472ef8-90a9-13c1-e4d8-44aad198cdbe), updating host OS, updating .NET on host OS, adding registry entries to Schannel, enabling group policy to use FIPS enabled ciphers, etc. Unfortunately none of these solved the issue. I tried to diagnose the issue with openssl/sslscan utilities, but they are also not able to connect to the server on port 1433. Client waits for 'server hello' during handshake and timeout happens. The Windows/system log shows the errors: 1. 36874 : An TLS 1.2 connection request was received from a remote client application, but none of the cipher suites supported by the client application are supported by the server. The SSL connection request has failed. 2. 36888: A fatal alert was generated and sent to the remote endpoint. This may result in termination of the connection. The TLS protocol defined fatal error code is 40. The windows schannel error state is 1205. Note that, same client can connect to another instance of SQL server 2016 hosted on another server without any issue. Could you please suggest what more configuration we are missing on SQL server 2014?"Create Table as" clause issue
Hey all there, I am trying to create a new table in MSSQL Server 2017 from two other existing tables. Currently, i am using "Create table as" clause but unfortunately it brings syntax error as in below screenshot attached. But, interestingly, same task is accomplished by using "Select INTO" clause.So my question is that "Create Table AS" is valid in MSSQL Server or not ?
