Merge change from MySQL AB: ChangeSet@1.2612, 2007-11-07 19:59:58+04:00, ramil@mysql.com +6 -0 Fix for bug #26447: "ALTER TABLE .. ORDER" does not work with InnoDB and auto_increment keys Problems: 1. ALTER TABLE ... ORDER BY... doesn't make sence if there's a user-defined clustered index in the table. 2. using a secondary index is slower than using a clustered one for a table scan. Fixes: 1. raise a warning. 2. use the clustered index. mysql-test/r/innodb.result@1.203, 2007-11-07 19:59:56+04:00, ramil@mysql.com +15 -15 Fix for bug #26447: "ALTER TABLE ..
