We saw 32036 errors when we tried to GRANT SELECT on some of the production views that have the WITH clause, much less trying to query against the view. The test case I posted was simple, mainly to illustrate the basic problem of not being able to do the SELECT with the second user.

Thanks for the extra testing. We weren't sure where the 32036s were coming from, or how related they were to the permission issue. Received on Tue Sep 09 2003 - 17:12:31 CDT
