|Subject:||Slow queries when using left join|
|View as plain text|
Dear MySQL forum. I have performance problems when using "left join x" combined with "where x.y is null", in particularily when combining three tables this way. Please contact me by e-mail if you are familiar with these issues and know how to eliminate slow queries. I would really appreciate your help.
