SELECT *
FROM
TableName
WHERE
ORDER BY
CASE @OrderByColumn
WHEN 1 THEN Forename
WHEN 2 THEN Surname
END;
我有一个类似上面的语句,它让我可以动态地选择如何对查询结果进行排序.但是,如何指定我想要 Forename 订购的 DESC
和 Surname ASC
?
I have a statement like above which lets me dynamically choose how to order the results of a query. However, how do I specify that I want the Forename ordered DESC
and the Surname ASC
?
你需要把你的ORDER BY
分成两部分:
You need to split your ORDER BY
in two parts:
SELECT *
FROM
TableName
WHERE
ORDER BY
(CASE @OrderByColumn
WHEN 1 THEN Forename
END) DESC -- Forename --> descending
, (CASE @OrderByColumn
WHEN 2 THEN Surname
END) ASC -- Surname --> ascending
