OUTPUT 语句使用

从msdn上截取的部分示例说明，记录下来以备使用.

A. Using OUTPUT INTO with a simple INSERT statement

USE  AdventureWorks;
GO
DECLARE   @MyTableVar   table ( ScrapReasonID  smallint ,
                           Name  varchar ( 50 ),
                           ModifiedDate  datetime );
INSERT  Production.ScrapReason
    OUTPUT INSERTED.ScrapReasonID, INSERTED.Name, INSERTED.ModifiedDate
         INTO   @MyTableVar
VALUES  (N ' Operator error ' ,  GETDATE ());

-- Display the result set of the table variable.
SELECT  ScrapReasonID, Name, ModifiedDate  FROM   @MyTableVar ;
-- Display the result set of the table.
SELECT  ScrapReasonID, Name, ModifiedDate 
FROM  Production.ScrapReason;
GO

 

B. Using OUTPUT with a DELETE statement

USE  AdventureWorks;
GO
DELETE  Sales.ShoppingCartItem
OUTPUT DELETED. *  
WHERE  ShoppingCartID  =   20621 ;

-- Verify all rows in the table that match the WHERE clause have been deleted.
SELECT   COUNT ( * )  AS   [ Rows in Table ]   FROM  Sales.ShoppingCartItem  WHERE  ShoppingCartID  =   20621 ;
GO

 

C. Using OUTPUT INTO with an UPDATE statement

USE  AdventureWorks;
GO
DECLARE   @MyTableVar   table (
    EmpID  int   NOT   NULL ,
    OldVacationHours  int ,
    NewVacationHours  int ,
    ModifiedDate  datetime );
UPDATE   TOP  ( 10 ) HumanResources.Employee
SET  VacationHours  =  VacationHours  *   1.25  
OUTPUT INSERTED.EmployeeID,
       DELETED.VacationHours,
       INSERTED.VacationHours,
       INSERTED.ModifiedDate
INTO   @MyTableVar ;
-- Display the result set of the table variable.
SELECT  EmpID, OldVacationHours, NewVacationHours, ModifiedDate
FROM   @MyTableVar ;
GO
-- Display the result set of the table.
-- Note that ModifiedDate reflects the value generated by an
-- AFTER UPDATE trigger.
SELECT   TOP  ( 10 ) EmployeeID, VacationHours, ModifiedDate
FROM  HumanResources.Employee;
GO
