title: Mysql too many while loops inside one stored procedure
body: <p>I have one stored procedure in while I am getting comma separated values in parameters. I have three parameters which has comma separated values. and i need to put them in table's columns so I am using while loop. but i am scared when too many(say lakhs of users) users will connect to my website then my procedure will have performance issues.<br>
  Does anyone have better solution on this issue?</p>
