Note that we have to bind the blob params with a large size for SQL Server
drivers, otherwise you can't insert into the database...
-> get SQLSTATE 07002 "COUNT field incorrect or syntax error" ... no idea why.
Other APIs like DB2 CLI don't need to pass a size in such case.
Don't know if this matters when using SQL_DATA_AT_EXEC with FreeTDS, but
wanted to warn you about this strange thing.
Note also that we use column-wise binding to fetch rows with:
The test does not use this but our driver does, so if you fix this problem
I can continue to test with our driver code.
