T-SQL提供了几种数据插入的语句：INSERT VALUES、INSERT SELECT、INSERT EXEC、SELECT INTO及BULK INSERT。
INSERT VALUES语句：
INSERT INTO dbo.Orders(orderid, orderdate, empid, custid) VALUES(10001, ‘20090212‘, 3, ‘A‘);
SQL Server 2008增强了VALUES语句的功能，允许在一条语句中指定由逗号分隔开的多行记录：
INSERT INTO dbo.Orders (orderid, orderdate, empid, custid) VALUES (10003, ‘20090213‘, 4, ‘B‘), (10004, ‘20090214‘, 1, ‘A‘), (10005, ‘20090213‘, 1, ‘C‘), (10006, ‘20090215‘, 3, ‘C‘);
在SQL Server 2008中还可以用VALUES来构建虚拟表：
SELECT * FROM ( VALUES (10003, ‘20090213‘, 4, ‘B‘), (10004, ‘20090214‘, 1, ‘A‘), (10005, ‘20090213‘, 1, ‘C‘), (10006, ‘20090215‘, 3, ‘C‘) ) AS O(orderid, orderdate, empid, custid);
INSERT SELECT语句，注意，目标表必须事先存在。
INSERT INTO dbo.Orders(orderid, orderdate, empid, custid) SELECT orderid, orderdate, empid, custid FROM TSQLFundamentals2008.Sales.Orders WHERE shipcountry = ‘UK‘;
INSERT EXEC语句
INSERT INTO dbo.Orders(orderid, orderdate, empid, custid) EXEC TSQLFundamentals2008.Sales.usp_getorders @country = ‘France‘;
SELECT INTO语句
SELECT orderid, orderdate, empid, custid INTO dbo.Orders FROM TSQLFundamentals2008.Sales.Orders;
SELECT INTO语句会复制来源表的基本结构（包括列名、数据类型、是否允许为NULL及IDENTITY属性）和数据。约束、索引及触发器不会从来源表中复制过来。
BULK INSERT语句
BULK INSERT dbo.Orders FROM ‘c:\temp\orders.txt‘ WITH ( DATAFILETYPE = ‘char‘, FIELDTERMINATOR = ‘,‘, ROWTERMINATOR = ‘\n‘ );
以下代码将删除具有最小订单ID值的50个订单，而不是随机删除50行：
WITH C AS ( SELECT TOP(50) * FROM dbo.Orders ORDER BY orderid ) DELETE FROM C;
INSERT INTO dbo.T1(datacol) OUTPUT inserted.keycol, inserted.datacol SELECT lastname FROM TSQLFundamentals2008.HR.Employees WHERE country = N‘USA‘;
OUTPUT子句为每个修改过的行返回一个输出行。如果有一个需求，出于审核的目的，需要把修改过的行的一个子集导入一个表：
INSERT INTO dbo.ProductsAudit(productid, colname, oldval, newval) SELECT productid, N‘unitprice‘, oldval, newval FROM (UPDATE dbo.Products SET unitprice *= 1.15 OUTPUT inserted.productid, deleted.unitprice AS oldval, inserted.unitprice AS newval WHERE SupplierID = 1) AS D WHERE oldval < 20.0 AND newval >= 20.0;
