Subject [jira] Commented: (DERBY-1808) [PATCH] Inbuilt functions SIGN, SQRT, RAND, RANDOM, COSH, SINH and TANH
Date Tue, 31 Oct 2006 16:00:57 GMT
    [ http://issues.apache.org/jira/browse/DERBY-1808?page=comments#action_12445930 ] 
Daniel John Debrunner commented on DERBY-1808:

The patch looks good, though the diff to EmbedDatabaseMetaData is messed up but it was easy
to fix.
I ran the metadata test which tests the escaped functions and it needed to have its master
file updated so i assume no tests were run against this patch.
When I find time I'll run all the tests to see if any other master files need updating, or
the contributor could do this.
