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
