I’m trying to run concurrent queries using single connection on Azure SQL Server using aioodbc client.

But i get this error

'HY000', 'The driver did not supply an error!'

If i run the functions one by one then its works fine.

Sample code:

output1, output2 = await asyncio.gather(
                        execute_fn1(cur, sql1),
                        execute_fn2(cur, sql2)
                    )

Does running parallel queries using single connection works on ODBC?
