Question

我正在寻找一种方法来排除我用作报告中显示的排序键的列。在Oracle中我可以简单地说COLUMN SORTKEY NOPRINT，但我还没能找到MySQL中的等价物。据我所知，我需要排序键，以便行以正确的顺序显示（借记，贷记，然后是总计）。

我正在使用的查询如下（它非常大）：

我不知道MySQL中允许这样做的任何功能，但我相信你可以在MySQL CASE中使用ORDER BY，所以你可能不需要。

/* Remove SORTKEY from SELECT */
...
ORDER BY
  CASE
    WHEN t.transaction_account = '111-111-111-111' THEN 1
    WHEN t.transaction_account = '222-222-222-222' THEN 2
  END;

从MySQL报告中排除临时列
