> Any way to hint a particular index for a query? >From the manual (http://www.mysql.com/doc/J/O/JOIN.html)
"As of MySQL Version 3.23.12, you can give hints about which index MySQL should use when retrieving information from a table. This is useful if EXPLAIN shows that MySQL is using the wrong index. By specifying USE INDEX (key_list), you can tell MySQL to use only one of the specified indexes to find rows in the table. The alternative syntax IGNORE INDEX (key_list) can be used to tell MySQL to not use some particular index. USE/IGNORE KEY are synonyms for USE/IGNORE INDEX." Also, have you done an 'analyze table iv_alert'?
