Hi,
Are there any guidelines for writing portable Java code using different SQL
DBMS engines? Specifically, I'm writing code that will be ultimately
deployed on Oracle. I don't really care for encumbering my disk with 300 MB
of Oracle stuff, just to have access to a bad ui (sqlplus) and a few
libraries. So I've started to do the code using Postgres but now, I'm at a
situation where I'm looking at being forced to install oracle. Here are some
of the issues I'm finding:
- setBytes() doesn't work as I expect. I have to use Oracle's RAW type and I
haven't been able to use setBytes correctly on Postgres. I'm not sure why,
yet. I get cast exceptions, for one but I don't know why that would
happen.
- sequences don't work the same. In my Java code, I have to get sequence
numbers. It's fairly easy in Postgres (select nextval ('seq')) but the
syntax in Oracle is different (select seq.nextval from DUAL).
I have to write Oracle-centric code in my Java stuff and I'm trying to see
if it's worth it to do some extra work to make it work or not. Anyone have
any comments on this?
