Hi @sathya08,

I'm not re-authenticating to the SQL server serverless for the authentication, but a one-time authentication to the workspace is required in my case. Without credentials, I'm getting below error. 

default auth: cannot configure default credentials

Looks like, if we don't provide any credential details it will search for the default credential set at my profile level.

For the query execution log, you can check in the Query History tab. Make sure you remove the filter from the user to see the complete logs. 

Thanks
