是否可以通過SQL Server 2008 R2中的聯接條件從兩個表中刪除數據？

Question

這是我的代碼。

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無法運行

Answer 1

希望這能奏效，請安全嘗試，

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

您還可以在此處指定條件，

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，並由其他人建議，Delete僅在單個表上起作用。

希望這項工作對您有幫助-

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)

以相同的順序執行。

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
