如何从一个SELECT语句插入到多个表中

Question

我想从一个select语句插入到多个表中。可能吗？

这是我想在这里做的事：

insert into table1 (Name, Address) 
insert into table2 (Name, Address) 
select Name, Address from MainTable 

Answer 1

可以使用OUTPUT条款插入到第二个表。如果你想插入两个以上的表格，你必须使用其他方法。

样本数据

DECLARE @MainTable TABLE (Name nvarchar(50), Address nvarchar(50)); 
DECLARE @T1 TABLE (Name nvarchar(50), Address nvarchar(50)); 
DECLARE @T2 TABLE (Name nvarchar(50), Address nvarchar(50)); 

INSERT INTO @MainTable (Name, Address) VALUES 
('Name1', 'Address1'), 
('Name2', 'Address2'), 
('Name3', 'Address3'); 

查询

INSERT INTO @T1 (Name, Address) 
OUTPUT inserted.Name, inserted.Address INTO @T2 (Name, Address) 
SELECT Name, Address 
FROM @MainTable 
; 

结果

SELECT * FROM @T1; 
SELECT * FROM @T2; 


+-------+----------+ 
| Name | Address | 
+-------+----------+ 
| Name1 | Address1 | 
| Name2 | Address2 | 
| Name3 | Address3 | 
+-------+----------+ 

+-------+----------+ 
| Name | Address | 
+-------+----------+ 
| Name1 | Address1 | 
| Name2 | Address2 | 
| Name3 | Address3 | 
+-------+----------+
