从MySQL报告中排除临时列

我正在寻找一种方法，将用作排序键的列从报告中显示出来。在Oracle中，我可以简单地说是

列SORTKEY NOPRINT

，但在MySQL中，我还没有找到一个等价的。据我所知，我需要排序键，以便按正确的顺序显示行（借记、贷记，然后合计）

我正在处理的查询如下（非常大）：

我不知道MySQL中有任何功能允许这样做，但我相信您可以在MySQL中使用

orderby

中的

CASE

，所以您可能不需要这样做

/* 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;

感谢您的回答，但不幸的是，这引发了一个

错误1054（42S22）：“order子句”中的未知列“t.transaction\u account”

错误。假设它在

SELECT

中起作用，它应该在

order BY

中起作用。请确保您确实有这样一个列，并且没有输入错误。我已经仔细检查了该列的输入和有效性。没问题。我不知道为什么它不起作用。这只是列的别名问题。因为在

ORDER BY

开始之前，该列标题为“Transaction”，所以我只需将

t.Transaction\u账户

更改为

Transaction

，并将

111-111-111

更改为“Debit”，等等。然后，它就可以正常工作了！
