    Re: MySQL quary in a query

    What do you mean by MySQL query in a query?
    I don't think its a good idea to marge multiple queries. What you can do is just use joiner or tolls present in Mysql for your help according to the scenario.
    Personally I don't combine multiple MySQL queries. Its better if you keep them separate. SO it wont get messy & you can always troubleshoot or work on your code at later time with less pain.

    Re: MySQL quary in a query

    Technically speaking its not supported in current MySQL environment to sent multiple queries in a single query. You can create procedures & triggers if you wish?
    According to MySQL & PHP what you want to do is not supported.

    Anyway I have a question about nested query.
    I have this code.

    Code:
    SELECT column_1, column_2, column_1
    FROM table1 a, table2 b
    WHERE a.playerid = b.playerid AND b.matchid
    IN (
    
    SELECT matchid
    FROM matches
    WHERE season =2000
    )
    GROUP BY nickname
    ORDER BY avg( score ) DESC
    Can anyone help?

    You need to learn the Update statement in SQL.
    I think this tutorial will help you.
