AFAIK no API returns the results you want. What Libgda could do is map each returned column to a GdaStatement expression if the statement executed is a SELECT. In your example the 1st column could be mapped to the expression "p.firstname AS name". Then it would be possible to add more attributes to the GdaColumn, the ones you want (i.e. the field name queried for example). Regards, Vivien
