my apologies, i thought serial number was type text,
but it is type varchar(). i will change it to text

this is the error...
Warning: pg_exec(): Query failed: ERROR: Cannot cast
type character varying to integer in
/home/home/adodb/drivers/adodb-postgres64.inc.php on
line 741
-1: ERROR: Cannot cast type character varying to
integer
it there is no error in 7.4.
