You have chosen to sponsor your bid up to a maximum amount of .
I currently have a mysql database with around 300,000 rows. It consists of 15 tables.
I need a mysql/php professional to perform various complicated queries and display the result in a page. (between 10-20 different queries) I'm going to tell what I want and you will perform the most optimized query.
The queries will include multiple joins, math functions like SUM and COUNT, etc. The key is to optimize the queries so that it runs as fast as possible with effective use of resources.
The task also requires restructuring of the mysql table if necessary which should include assigning indices to necessary columns of table.
For an experienced mysql professional this task shouldn't be that difficult. For any other people this tasks will be difficult and extremely time-consuming and we'll be wasting each others time.
So please bid only if you are well experienced (at least 3 years) in mysql and php.
