mySQL Query Help

Hello, I looked at your query, and it is pretty clear to me how to make it faster: 1. you need an index on gpspushhistories consisting of vehicle_id and created_at (in that order). 2. condition DATE(gpspushhistories.created_at) = CURDATE() -1 must be rewritten to be range restriction query 3. There is no need for outer join on vehicles. Depending on the definition of user_id, you probably don't need left join with users table too. 4. Of course, you don't need all these unions. You should utilize IN predicate. I can have it all re-written, index created, and tested in an hour. Regards, Mirko.

Hi I have checked your mysql query freelancer|project scope of word document carefully. The SQL UNION ALL operator is used to combine the result sets of 2 or more SELECT statements. It does not remove duplicate rows between the various SELECT statements (all rows are returned). Each SELECT statement within the UNION ALL must have the same number of fields in the result sets with similar data types. Build query is main on site speed. if you hire me you will not waste time. Now i am ready to work.
