SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

Hi Artyom,

Im referring to this error message:

cppdb::invalid_column attempt access to invalid column

Without specifying the wrong column name in the error, how can you tell
whats wrong?

I guess you are trying to get a coloumn by its name? Try to get it via 
its position instead. As I posted some times ago, never use SELECT * ! 
If you do so, you can define the order of the coloums and get them via 
the position. Also it's faster.
For you problem:
     either make a solution on your own and then commit as a patch
or make a feature request tracker.

Regards

Yes I know however my app generates tables and while the column order is
usually preserved it's not always the case.

The other problem was some tables have a lot of columns > 20. Accessing
them by index sbecomes a pain especially when its still under development
and things change.
