Hi:

I think setObject() has been discussed extensively on
this list
(particularly with setting null values). However,
consider the following:

In PSQL:
    test=# create table foo (number_column int);

Now in Java:
    PreparedStatement ps = con.prepareStatement(
        "insert into foo (number_column) values (?)"
        );
    ps.setObject(1, "123");
    ps.executeUpdate();

This will throw a Driver exception. Is this expected
behavior
or should the driver do a Integer.parseInt(...) on the
string value
as needed ?

This is not a show-stopper or even a serious bug in my
code
and is easy to workaround. I'm just curious as to the
"right"
behavior as per the JDBC spec.....

Best regards,
--j
