如何从一个SELECT语句插入多个表

Question

我试图从一个select语句插入多个表。有可能吗？

以下是我在这里要做的事情：

(Array -> Parser a)

Answer 1

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

示例数据

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');

<强>查询

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

<强>结果

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


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

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

             (student_id,syrid) 
      VALUES (
               (
                SELECT student_id 
                  FROM student
                ), (
                     SELECT syr_id 
                       FROM school_year
                   )
