Description:

Hi,

I am trying to return a result set using dynamic query from a postgresql
function.

Function runs ok but when returning bit data type in one of the columns from
output table, I get it as "bit" which should be bit only. Now executing same
query outside of the function in normal mode, it returns column with bit
data type only.

Please guide me.

Regards,
Vicky
