插入数据

　　我们可以通过以下几种方式向表中插入数据。分别是INSERT VALUES，INSERT SELECT，INSERT EXEC，SELECT INTO和BULK INSERT共五种方法。为了演示，我们先在数据库tempdb中创建表dbo.Orders，然后分别用这几种方法向表中插入数据，下面是示例代码。

USE tempdb;GOIF OBJECT_ID('dbo.Orders','U') IS NOT NULL DROP TABLE dbo.Orders;GO-- 创建表OrdersCREATE TABLE dbo.Orders(    OrderID INT NOT NULL,    OrderDate DATETIME NOT NULL        CONSTRAINT DFT_OrderDate DEFAULT(CURRENT_TIMESTAMP),    EmpID INT NOT NULL,    CustID VARCHAR(20) NOT NULL,    CONSTRAINT PK_Orders PRIMARY KEY(OrderID));-- 插入数据-- 方法一：INSERT VALUES(基于指定值的行)INSERT INTO dbo.Orders ( OrderID, OrderDate, EmpID, CustID )VALUES ( 10001, '20140917',1,'A'),        (10002,'20140916',2,'B'),        (10003,'20140915',3,'C'),        (10004,'20140914',4,'D');                -- 方法二：INSERT SELECT(基于SELECT查询返回行，基于已有表)INSERT INTO dbo.Orders ( OrderID, OrderDate, EmpID, CustID )    SELECT orderid,orderdate,empid,custid FROM TSQLFundamentals2008.Sales.Orders    WHERE shipcountry='UK';    -- 方法三：INSERT EXEC(基于存储过程或动态SQL返回结果，基于已有表)INSERT INTO dbo.Orders ( OrderID, OrderDate, EmpID, CustID )    EXEC TSQLFundamentals2008.dbo.usp_GetOrders @Country = N'France';    -- 方法四：SELECT INTO(创建目标表，用查询结果填充，创建新的表)IF OBJECT_ID('dbo.Orders','U') IS NOT NULL DROP TABLE dbo.Orders;GOSELECT orderid,orderdate,empid,custid INTO dbo.OrdersFROM TSQLFundamentals2008.Sales.Orders;-- 方法五：BULK INSERT(将文本文件中的数据导入到已存在的表中，基于已有表)BULK INSERT dbo.Orders FROM 'D:/mcgrady/temp/TSQLFundamentals20090201/orders.txt'WITH (    DATAFILETYPE= 'char', --指定字符格式    FIELDTERMINATOR= ',', --指定字段终止符    ROWTERMINATOR= '/n' --指定行终止符);
