mysql query will not run faster

Question

This is my query

    SELECT `tbl_user`.`file_id` , `tbl_user`.`folder_id` , `tbl_user`.`user_id` , `tbl_user`.`fathername` , `tbl_user`.`investor_type` , `tbl_user`.`user_name` , `account_id` , `user_witness_id` , `visible` , sum( tbl_user_payment.user_amount ) AS amt, `tbl_user_payment`.`trans_type`
FROM (
`tbl_user`
)
LEFT JOIN `tbl_user_payment` ON `tbl_user`.`user_id` = `tbl_user_payment`.`user_id`
LEFT JOIN `tbl_user_stamp` ON `tbl_user_stamp`.`user_id` = `tbl_user_payment`.`user_id`
WHERE `tbl_user`.`visible` = '1'
AND `tbl_user`.`user_name` LIKE '%1%'
OR `tbl_user`.`file_id` LIKE '%1%'
OR `tbl_user`.`folder_id` LIKE '%1%'
OR `tbl_user`.`fathername` LIKE '%1%'
OR `tbl_user`.`nic` LIKE '%1%'
OR `tbl_user`.`email` LIKE '%1%'
OR `tbl_user`.`city` LIKE '%1%'
OR `tbl_user`.`phone` LIKE '%1%'
OR `tbl_user`.`bank_account` LIKE '%1%'
GROUP BY `tbl_user`.`user_id`

on my local system it take about 2 seconds first time and then it will take about 0.002 seconds after that

but on live server it will not go less than 2 seconds

Can some one plz help me

and the recods are about 1000 only in user table and user_stamp table and abuot 1200 in user_payment table

Thankx

Answer 1

I would guess that the query cache is not activated on your live server.

You want to check your MySQL live server configuration.

Answer 2

That probably means that caching is turned on on your machine, and turned off on the live machine. Try doing different searches on your local machine, those should all be taking about the same time.

Answer 3

You can Create VIEW on MySQL to collect data from tables instead of using join and select only from the view , that will make your data shown more faster..

Answer 4

Using LIKE this way will not use indexes. To make use of indexes, you must search from the begginning of the string ('1%'), or just stop usng LIKE, if you don't really need it. It may run faster on your system due to better specs or/and less load.
