我可以通过SQL Server 2008 R2中的连接条件从两个表中删除数据吗？

Question

这是我的代码。

DELETE tbemp.emp_id, 
        tbadd.emp_id 
FROM  TBEMPLOYEE tbemp 
INNER JOIN TBADDRESS tbadd ON (tbemp.emp_id=tbadd.emp_id)

它不起作用。 SQL Server 2008 R2不运行它

Answer 1

希望这应该有用，安全一下，

DELETE TBEMPLOYEE FROM 
TBEMPLOYEE INNER JOIN 
TBADDRESS ON (TBEMPLOYEE.emp_id = TBADDRESS.emp_id)

您还可以在此处指定条件

WHERE COL IN ('A','B',...)

Answer 2

您正在使用列名（DELETE tbemp.emp_id，tbadd.emp_id）代替表名并由其他人建议，Delete仅适用于单个表。

希望这对你有用 -

DELETE TBEMPLOYEE FROM 
TBEMPLOYEE INNER JOIN 
TBADDRESS ON (TBEMPLOYEE.emp_id = TBADDRESS.emp_id)

DELETE TBADDRESS FROM 
TBEMPLOYEE Right JOIN 
TBADDRESS ON (TBEMPLOYEE.emp_id = TBADDRESS.emp_id)

以相同的顺序执行。

Answer 3

declare @Tbl table ( emp_id int)

DELETE from tbemp
output deleted.emp_id into @t

FROM  TBEMPLOYEE tbemp 
JOIN TBADDRESS tbadd ON tbemp.emp_id=tbadd.emp_id

DELETE from tbadd

FROM TBADDRESS tbadd 
join @T T ON T.emp_id=tbadd.emp_id
