sqlserver2005 技巧

1.利用 ROW_NUMBER 实现分页
     ROW_NUMBER() 就是生成一个顺序的行号,而他生成顺序的标准,就是后面紧跟的OVER(ORDER BY ReportID)。

-- 按Freight从小到大排序，求20到30行的结果 
select   *   from ( 
     select  OrderId, Freight, ROW_NUMBER()  OVER ( order   by  Freight)  as  row  from  Orders 
) a 
where  row  between   20   and   30  

2.TOP的参数

-- 前n名的订单
declare   @n   int  
set   @n   =   10  
select   TOP ( @n )  *   from  Orders 

3.排名

select   *   from ( 
     select  OrderId, Freight, RANK()  OVER ( order   by  Freight)  as  rank  from  Orders 
) a 
where  rank  between   20   and   30

4.try ... catch

SET  XACT_ABORT  ON    --  打开 try功能 
BEGIN  TRY 
     begin   tran  
         insert   into  Orders(CustomerId)  values ( - 1 ) 
     commit   tran  
     print   ' commited '  
END  TRY 
BEGIN  CATCH 
     rollback     
     print   ' rolled back '  
END  CATCH 

5.通用表达式CTE
通过表达式可免除你过去创建临时表的麻烦。特别，通过表达式还支持递归。

-- 例子：结合通用表达式进行分页
WITH  OrderFreight  AS ( 
     select  OrderId, Freight, ROW_NUMBER()  OVER ( order   by  Freight)  as  row  from  Orders 
) 
select  OrderId, Freight  from  OrderFreight  where  row  between   10   and   20  

6.直接发布web service
想要把store procedure变成Web Service就用这个吧，.NET, IIS都不需要，通过Windows 2003的HTTP Protocol Stack直接发布WebService,用这个功能需要Windows 2003 sp1

-- DataSet CustOrdersOrders(string customerID) 
CREATE  ENDPOINT Orders_Endpoint 
state = started 
as  http( 
    path = ' /sql/orders ' , 
    AUTHENTICATION = (INTEGRATED), 
    ports = (clear) 
) 
for  soap( 
    WebMethod  ' CustOrdersOrders ' (   
        name = ' Northwind.dbo.CustOrdersOrders '  
    ), 
    
    wsdl = default , 
     database = ' Northwind ' , 
    namespace = ' http://mysite.org/ '  
) 

Web Service就发布好了，敲入http://localhost/sql/orders?wsdl得到wsdl
