SQL - 返回已刪除的行

Question

我想結合一個返回行的SELECT和一個刪除我選擇的行的子集的DELETE？

這可能嗎？

Answer 1

如果您有一條SELECT語句返回所有候選項，只需將SELECT更改爲DELETE OUTPUT DELETED *。

SELECT * 
FROM tbl1 
INNER JOIN tbl2 on tlb1.col = tbl2.col 
INNER JOIN tlb3 on tbl2.anothercol = tbl3.somecol 
WHERE blah blah blah 

能成爲：

DELETE tbl1 OUTPUT DELETED.* 
FROM tbl1 
INNER JOIN tbl2 on tlb1.col = tbl2.col 
INNER JOIN tlb3 on tbl2.anothercol = tbl3.somecol 
WHERE blah blah blah
