Hi,

The order or conditions in SQL WHERE clause doesn't have impact on the overall performace. If you need to speed up SQL query and you are working with large database, you can try to use a temporary table.

Using of temporary tables and multiple separated queries may be faster sometimes, mainly in case of large tables.
