single_query

[sql.config DP4_database_name]
single_query=0

Some databases, notably Microsoft SQL Server, have very severe restrictions on how different cursors can be used in the same connection.

Set single_query=1 if the SQL database will not allow you to execute a new SELECT cursor while an existing query is still open.

Set single_query=2 if the SQL database will not allow you to execute any SQL statement while a fetch is open. single_query=2 is required for accessing SQL Server databases via AUXWODBC.
