    Override MySQL's check for accidental large queries · f4e4b44f

    Bug 1070046: MySQL has an optional server config option, "MAX_JOIN_SIZE",
    which throws an error if you try to run a SQL query that MySQL's strategizer
    thinks will require it to evaluate more than MAX_JOIN_SIZE rows. This is
    intended to prevent the user from accidentally running giant queries that
    will never finish, but some Mahara queries (which are large but will finish)
    can trip it. Adding SQL_BIG_SELECTS=1 tels it that our queries are *not*
    accidentally large.
    Also has order change for bug 1184450
