Обсуждение: Calling functions with smallint fails

I'm having problems using CallableStatement to execute a function that
has a smallint parameter. The problem I'm having is identical to this
bug report:

http://archives.postgresql.org/pgsql-bugs/2003-04/msg00060.php

 From a basic examination of the code, it seems that setShort(int,
short) simply serializes the value to a string, making it
indistinguishable from an integer. The response to that bug mentions
that the literal needs to be cast to a smallint:

http://archives.postgresql.org/pgsql-bugs/2003-04/msg00061.php

Is this a known problem with the JDBC implementation, or is this a bug
that can be fixed?

christian.

This has been fixed in the 8.0 driver series as all calls are now strongly
typed.

Thanks for the quick reply on both issues. The new driver works as
advertised.

Hi, Kris,

And this just broke the persistence abstraction layer in one of our
legacy apps, as they use code like setString(i, obj.toString()) for
everything including Number types. :-(

Now, we have an additional reason to throw this crappy code away, and
replace it with hibernate :-)


Thanks for your great work.
