sql-server - 列不会绑定

Question

我有以下语句作为存储过程的第一步

As
BEGIN
SET NOCOUNT ON
  DELETE DB1.dbo.Members WHERE DB1.dbo.members.ID = DB2.dbo.in_table.ID
  --after the delete I will insert all of the new data from in_table to Members
END

DB2.dbo.in_table.ID 不会绑定。存储过程设置为存储在 DB2 上。DB1 位置完美绑定。是数据库权限问题吗？

Answer 1

您没有在查询中的任何位置引用或加入第二个表：

DELETE 
FROM DB1.dbo.Members 
WHERE EXISTS (SELECT ID 
                FROM DB2.dbo.in_table 
                WHERE DB1.dbo.Members.id = B2.dbo.in_table.ID)
