Sometimes the BDE is more forgiving. Also are you connecting to your
database with Dialect 1 or Dialect 3? And, which version of Interbase
or Firebird are you using?

What are the datatypes of the 2 columns? If the datatypes are
significantly different(one varchar bigger than the other), then you
might encounter problems. I'm currently using queries where the same
parameter name is used with against more than one column, but I make
sure the columns are of the same datatype and almost the same size.
