arrow-flightsql-odbc's Issues

Received RecordBatch prior to Schema for query

Hi,

I am using arrow-flightsql-odbc to setup a flightsql service which could convert MSSQL result to arrow data. The MSSQL is setup without a problem. It could also connected with MSSQL ODBC Driver 18. But when I tested the service with flight_sql_client, I always got an error "Received RecordBatch prior to Schema". I am not sure what is wrong. Could you please help to indicate how to fix this problem? Thanks in advance! Please see details below.

The flight_sql_client is from arrow-flight.
