Misleading description

  • 3

    Description suggests that we should use UPDATE statement: "with a single update query and no intermediate temp table". But it turns out that solution with UPDATE is invalid, and in fact we must use SELECT statement.

    @cpp0x Hi, I am the editor of this problem and I am sorry to confuse you. This is actually update statement but previously update has some permission issue. Now it has been fixed.

    Thanks for the feedback and enjoy coding...
