Subject [jira] Updated: (OPENJPA-1615) CriteriaQuery test failures on MSSQL
Date Wed, 14 Apr 2010 18:34:48 GMT

     [ https://issues.apache.org/jira/browse/OPENJPA-1615?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Donald Woods updated OPENJPA-1615:
----------------------------------

    Assignee:     (was: Donald Woods)

So, does runtime code need to be changed to fix this?  There is a solution, that we should
be using "%" instead of "MOD" when using MSSQL....

> Seeing 2 different testcase failures in TestTypesafeCriteria for MSSQL:
> 1)  MSSQL doesn't support the MOD() function syntax but expects "%" instead, which is
set in the SQLServerDictionary as "supportsModOperator = true", but CriteriaBuilderImpl and
Expressions is ignoring this option when generating the JPQL, so the testFunctionWithTwoArgument()
and testFunctionWithFunctionArgumentInOrderBy() tests fail -
