Hello!

A quotation from the Hibernate 2.1.7 changelog:
Quote:
improved handling of long strings (now uses LONG instead of VARCHAR2) on Oracle8 (Harry Schittler)


Is there any reason why this is done? When creating a schema, all the former varchar2 columns are now long columns. This imposes many problems: For example, there cannot be more than 1 long column in Oracle, and a long column cannot be the primary key of a table.

Because of these two issues, the JUnit test reports fail with a few dozen errors when using Oracle 8.1.7 or Oracle 9.2.

Does anybody else see these problems?

Greetings,
Christian

Confirmed, this was a mistake. Please use the Oracle9Dialect for both, they should work fine (except for long strings on Oracle8, that was the wrong fix). We'll release an update...

Unfortunately, one cannot use the Oracle9Dialect with an Oracle 8 database, because there are some differences e.g. in the outer join syntax.

But it's good to hear that the bug will be fixed...

Tanks a lot!
