Question

我正在尝试这个SQL语句一次从两个表中删除，但我发现它只是从一个表中删除并给我一个错误

DELETE语句与REFERENCE约束冲突＆＃34; FK__cc_custom__custo__02084FDA＆＃34;。冲突发生在数据库＆＃34; CurtainClub＆＃34;，table＆＃34; dbo.cc_customer_address＆＃34;，column＆＃39; customer_number＆＃39; .`

我的sql语句如下：

BEGIN
SELECT * from cc_customer 
inner join cc_customer_address on customer_id=customer_number

delete from cc_customer where customer_id=3
delete from cc_customer_address where customer_number=3
END

另请注意，customer_number是customer_id

的外键

Answer 1

您应该交换DELETE语句：

BEGIN
  SELECT * 
  from cc_customer 
  inner join cc_customer_address on customer_id=customer_number;

  delete from cc_customer_address where customer_number=3;  -- first child
  delete from cc_customer where customer_id=3;              -- then parent
END
