    Hi,
    Does anyone know how to refer to a mysql table column using a number instead of the column's name? For example, if it is the 4th column I'd like the select query to include:
    ORDER BY '$sortnumber'
    and the variable $sortnumber will be the number 4.
    Thanks,
    Clive

    Best bet IMO is to build the SQL query inside of a different language (probally whatever your program is built in).

    Hi DrP,

    In MySql, the ORDER BY part of a SELECT statement refers to the position of the field in the selection not in the table.

    Example :

    SELECT fieldname4, fieldname7, fieldname5 ... FROM table ORDER BY 2 ASC

    The result will be sorted on ascending fieldname7.
