@tdcmeehan @skairali please review and merge.

[Akanksha-kedia]

we are still using still old version when new versions are compatible and non-vunerable.

@Akanksha-kedia have you tested the SQL server driver with the updated dependency?

Hi @Akanksha-kedia
Thank you for the PR. I don't see UT added for sql-server connector currently, I will add an issue regarding the same. So I have the same question as Tim, did you test sql-server connector after updating the dependency and could you please share the results?

[agrawalreetika]

I have added issue for adding UTs here - #21890
Also found out that product tests for sql-server were disabled as part of microsoft/mssql-docker#76
and as per the comment here, the Issue no longer exists if we make use of microsoft/mssql-server-linux:2017-CU13 docker image instead.
It would be good if you want to enable Product tests for it and test out your changes as well.
