Power Query connector valid ODBC connection before reuse

Submitted by on ‎10-16-2025 06:44 PM

Our connector uses Odbc.DataSource. If a developer works long hours on a single report in Power BI Desktop, the ODBC connection may become dead, thus causing an error when Power BI Desktop executes a query over this dead connection.

 

I would suggest Power BI to validate the ODBC connection using 

SQLSetConnectAttr(conn, SQL_ATTR_CONNECTION_DEAD, ..) before executing a query. If it's dead, reallocate a new one.
