[hibernate-issues] A Little bug in 3.2.1

[Urban.Lindberg at tietoenator.com]

Hi

I believe I just discovered little bug in Hibernate 3.2.1.

If you have a table named VC and a column with the same name (VC) and
you define this HQL:

Strinh hbsql="update VC set timestamp='xxxx' where VC =:vcId"

session.createQuery(hbsql).setString("vcId",
aVC.getVcId()).executeUpdate();


You will get a Nullpointer in SessionFactoryHelper.findSQLFunction there
is a easy workaround, just rename the VC java object to something
different then the column name.

I post it here and maybe someone wll be helped by it, it took me some
hours before I found it. I believe this occured in 3.2.1 because it has
worked in an erlier version, 3.0.x. (don't rember exactly which we used
earlier)

Here is a trace:
