Hi everyone, I've been looking at the most recent change to AbstractStatementExecutor and it seems to assume that if a DDL statement, in general, results in a commit that this will also happen for a temporary table. In the case of MySQL, at least, this is not the case. The code in AbstractStatementExecutor goes and creates the temporary table in a new connection, which, in the case of MySQL, will not be visible in the current transaction. http://fisheye.jboss.com/browse/Hibernate/branches/Branch_3_2/Hibernate3/... If this turns out to be a bug, I will create an isolated test case for it and log a bug in JIRA. Donnchadh
