Thread: Mapping Java BigDecimal

Hi All,

We decide add support PostgreSQL database (now supporting only Oracle
database) to our product.

In Oracle we mapping Java BigDecimal to number(19, 2), in PostgreSQL to
numeric(19, 2).

If I store to "BigDecimal column" number without decimal, e.g. "3", than
Oracle JDBC driver return "3", but PostgreSQL JDBC driver return "3.00".

Is there some way (mapping, server setup,...) how reach return number
without trailing zeroes on decimal position?

I'm using PostgreSQL v. 8.1.18 (default for CentoOS 5.3).
Thank you all

There's no difference between those two values in Java's BigDecimal.

Are you saying that the 'scale' of the returned values differs between the
JDBC for Oracle and that for PG?
