How to access an ODBC DataSource in QGIS?
You can connect to an ODBC datasource in the “add vector layer” dialog, just select “database” as the source type and ODBC as the database type. QGIS uses the ODBC driver for OGR, so the same caveats will apply – that is you will need a table called GEOMETRY_COLUMNS and so on, so your colleague will probably need to modify the database.
What kind of driver does QGIS use for OGR?
QGIS uses the ODBC driver for OGR, so the same caveats will apply – that is you will need a table called GEOMETRY_COLUMNS and so on, so your colleague will probably need to modify the database.

Can a QGIS query be performed on a PostgreSQL database?
Allows a SQL database query to be performed on a PostgreSQL database connected to QGIS and loads the result. The algorithm won’t create a new layer: it is designed to run queries on the layer itself. Set all the values of an existing field to a fixed value. The SQL query string will be:
