Did you try to explicitly give the type for the literal?
e.g. ''::varchar

Subject: [SQL] query configuration for validate empty quote to zero
We just changed the postgresql server and got some problem with sql command
in our old server we can exexute this query:
SELECT * FROM product WHERE prdtnumber = ''
field prdtnumber data type is integer and the empty quote somehow can be assumed into 0 (zero)
Now, if I use the same query it return an error:
invalid input syntax for integer: ""
Anyone know what's the problem??
Thanks
Yudie
