Description

Using DB_UNIXODBC with an Azure SQL database works, however when starting Kamailio, errors are shown for :

26(80403) ERROR: db_unixodbc [connection.c:219]: db_unixodbc_extract_error(): unixodbc:SQLDriverConnect=01000:3:5701:[Microsoft][ODBC Driver 17 for SQL Server][SQL Server]Changed database context to 'database-name'.
ERROR: db_unixodbc [connection.c:219]: db_unixodbc_extract_error(): unixodbc:SQLDriverConnect=01000:2:5703:[unixODBC][Microsoft][ODBC Driver 17 for SQL Server][SQL Server]Changed language setting to us_english.

Regarding changing the DB context, the database to be used is defined in my odbc.ini file

[dsnName]
Driver=ODBC Driver 17 for SQL Server
Description=Azure MS SQL Server
Trace=No
Server=tcp:azure-sql-server-name.database.windows.net,1433
Encrypt=yes
TrustServerCertificate=no
Connection Timeout=30
Database=databaseName

I'm not able to USE databaseName when connecting to an Azure DB. The default language is already US-English, and i'm guessing it's also Azure specific that it cannot be changed?

Troubleshooting

I'm not sure what troubleshooting can be done with this. The DB connection works, it's just these commands that fail, but since the result is already correct, it doesn't seem to functionally matter, aside from the errors being thrown.

Reproduction

This can be reproduced using an Azure SQL database. Create a single database and a dedicated user (with db_owner membership), and configure the ODBC connection as above.

Debugging Data

I'm not sure any additional debugging information is available. I'm happy to provide anything specific requested.

Possible Solutions

I would suspect that a parameter could be added to the DB_UNIXODBC module to make each of these behaviors (changing database and changing language) optional. Default config would retain the existing behavior, so it's just an override if desired.
