SQL INSERT INTO SELECT 語句

---

通過 SQL，您可以從一個表複製信息到另一個表。

INSERT INTO SELECT 語句從一個表複製數據，然後把數據插入到一個已存在的表中。

INSERT INTO Customers (CustomerName, Country)
SELECT SupplierName, Country FROM Suppliers
WHERE Country='Germany';

建立學生表：

create table student(

Sno char(6) primary key NOT NULL,

Sname varchar(8) NOT NULL,

Ssex char(2),

Sage smallint,

sdept varchar(15)

)

use student

GO

create table course(

Cno char(4) primary key NOT NULL,

Cname varchar(20) NOT NULL,

Cpno char(4),

Ccredit tinyint

)

create table SC(

Sno char(6) NOT NULL,

Cno char(4) NOT NULL,

Grade decimal(12,2),

primary key(Sno,Cno)

)

insert into student 

Values('201601','劉一','男','20','數學')

insert into student 

Values('201602','劉二','男','21','語文')

insert into student 

Values('201603','趙茵','男','20','SX')

insert into student 

Values('201604','楊華','女','21','JSJ')
