From 41ccbefcc4cbf75c18e37746bd52617f6c9794b9 Mon Sep 17 00:00:00 2001 From: Gleb Shchepa Date: Fri, 28 Nov 2008 20:13:12 +0400 Subject: Bug #33461: SELECT ... FROM USE INDEX (...) throws an error Even after the fix for bug 28701 visible behaviors of SELECT FROM a view and SELECT FROM a regular table are little bit different: 1. "SELECT FROM regular table USE/FORCE/IGNORE(non existent index)" fails with a "ERROR 1176 (HY000): Key '...' doesn't exist in table '...'" 2. "SELECT FROM view USING/FORCE/IGNORE(any index)" fails with a "ERROR 1221 (HY000): Incorrect usage of USE/IGNORE INDEX and VIEW". OTOH "SHOW INDEX FROM view" always returns empty result set, so from the point of same behaviour view we trying to use/ignore non existent index. To harmonize the behaviour of USE/FORCE/IGNORE(index) clauses in SELECT from a view and from a regular table the "ERROR 1221 (HY000): Incorrect usage of USE/IGNORE INDEX and VIEW" message has been replaced with the "ERROR 1176 (HY000): Key '...' doesn't exist in table '...'" message like for tables and non existent keys. mysql-test/r/view.result: Added test case for bug #33461.
