Re: serious problems with BOOL and Access

I have managed to get bools to work with Access and VB.

My set up is:

On the windows side:
variables are declared as boolean
Bools as char is OFF
Maxlongvarchar=4094 (Not part of the bool problem but fixed another
problem)
Row versioning ON

On the PG side:
variables declared as bool
int4eq functions and operators for xid/int and bool/int as described
in the ODBC doco.

HTH,
