tsql - 删除最后一行

Question

我想从表中删除满足某些条件的最后一行。

DELETE TOP 1 FROM SOME_TABLE
WHERE SOME_COULMN = @VALUE
ORDER BY 1 DESC

Answer 1

DELETE FROM SOME_TABLE
WHERE UNIQUE_ID = 
(SELECT TOP 1 UNIQUE_ID
FROM SOME_TABLE
WHERE SOME_COLUMN = @VALUE
ORDER BY SOMETHING DESC)

Answer 2

DELETE和UPDATE语句需要括号（）表示行数参数

DELETE TOP （1） FROM SOME_TABLE 在哪里SOME_COULMN = @VALUE 订购1 DESC
