[hibernate-issues] [Hibernate-JIRA] Created: (HHH-3458) Register postgres random() function as "rand" in PostgresSQLDialect

Register postgres random() function as "rand" in PostgresSQLDialect ------------------------------------------------------------------- Key: HHH-3458 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3458 Project: Hibernate3 Issue Type: Improvement Components: build Affects Versions: 3.2.5 Environment: Postgres 8.3 Reporter: Stephen Cresswell Priority: Trivial I have an HQL query which uses "order by rand()". This works fine in our local integration tests (which are run against hsqldb), but fails against our build integration tests which runs postgres. The reason the query fails is because postgres function for "rand" is called "random". We can workaround this by dynamically detecting the db driver and generating db specific queries, but it strikes me that the cleanest solution for this is to simply re-register postgres' random function as "rand" in the PostgresSQLDialect, i.e. registerFunction( "random", new NoArgSQLFunction("random", Hibernate.DOUBLE) ); registerFunction( "rand", new NoArgSQLFunction("random", Hibernate.DOUBLE) ); -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
