According to MySQL doc, I must use union and temporary tables. It seems I have to do something along the line of this:
http://www.ricroberts.com/articles/2007/09/25/mysql-temporary-tables-and-rails There are cases where I use OR queries quite often. I am talking about queries like this "where column_1 = 123 OR column_2 = 123". It seems MySQL indices cannot properly optimize this. Are there plugins or snippets out there that automagically hide the complexity of using temporary tables for such queries? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
