Subject [jira] Commented: (DERBY-766) Improve code generation to handle 5000 unions in a select the union test in largeCodeGen
Date Wed, 31 Oct 2007 17:18:50 GMT

Kathey Marsden commented on DERBY-766:
--------------------------------------

Mamta suggested changing JoinNode.getNumJoinArguments() from 12 to 11, which seemed to fix
up the simple test case. Thanks Mamta! I will run the full set of tests.  What is not clear
to me is why this change was not needed in the original change. Trunk returns 11 too, but
that change was due to DERBY-1700 removal of a totally different parameter.

> A good incremental improvement for code generation for 10.2 would be to handle 5000 unions
in the  largeCodeGen test.
> eg.   largeUnionSelect(con, viewName, 5000);
> should pass.
