sql - 如何从一个 SELECT 语句插入多个表

Question

我试图从一个 select 语句插入到多个表中。是否可以？

这是我在这里尝试做的事情:

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

Answer 1

您可以使用 OUTPUT 子句插入到第二个表中。如果要插入两个以上的表，则必须使用其他方法。

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 |
+-------+----------+
