----------------------------------------------------------------------
Key: HHH-2715
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2715
Project: Hibernate3
Issue Type: Patch
Components: core
Affects Versions: 3.2.4.sp1
Environment: hibernate 2.1.4 - database: DB2 for 0S390 v7.1 - OS390
Reporter: Eric Georges
supportsUniqueConstraintInCreateAlterTable return true. For IBM DB2 on OS 390 it must
return false.

<hibernate-mapping>
<class name="events.Event" table="EVENTS">
<id name="id">
<column name="ID" unique-key="ID_IDX"

</id>
<property name="date" type="timestamp"
column="DATE"></property>
<property name="title" type="string"
column="TITLE">
</property>
</class>
</hibernate-mapping>
Actually it generate this :
create table EVENTS (ID int not null, DATE timestamp, TITLE varchar(255), primary key
(ID), unique (ID))
if supportsUniqueConstraintInCreateAlterTable return false it does :
create table EVENTS (ID int not null, DATE timestamp, TITLE varchar(255), primary key
(ID))
create unique index ID_IDX on EVENTS (ID)
the right SQL code for DB2 v7 on OS390
