How many values in an “in” clause is too many in a SQL query?

Question

I have a SQL query that uses the values of an array in its WHERE clause:

 $ids = array 
         ( 
           [0] => 1 
           [1] => 2 
           [2         


        

Answer 1

think of..if you have to write 5 pages or 10 what takes longer...it's normal if you have a huge amount of ids to take the query longer.You should look and assure that your data is not repeating because that will make the query take longer for unnecessary data..
