Annex D (informative) Deprecated features It is intended that the following features will be removed at a later date from a revised version of this part of ISO/IEC 9075: 1) The ability to specify UNION JOIN in a <joined table> has been deprecated. It's the only one. I sent a patch to the patches list for JOIN documentation. In it, the only thing I said about UNION JOIN is "Deprecated." Let me know if I should change that. I thought about omitting it entirely. -- -------- Robert B.
