有人请帮助我。

我在 SQL Server 2005 中有一个用于数据分页的存储过程(见下文)。存储过程的目的是返回特定类别 (CatID) 的产品页面 (prodid, description)。

当我执行存储过程时:

EXEC @return_value = [dbo].[ecosys_CNET_GetCategoryProducts]  
@CatID = N'AA',  
@PageNumber = 1,  
@ProductsPerPage = 10,  
@HowManyProducts = @HowManyProducts OUTPUT 

即使有很多产品,它也只返回一 (1) 行:

@HowManyProducts: 10034

我有一个类似的存储过程,它适用于较小的数据集。我达到某种极限了吗?

set ANSI_NULLS ON  
set QUOTED_IDENTIFIER ON  
go  

CREATE PROCEDURE [dbo].[ecosys_CNET_GetCategoryProducts]  

(  
@CatID char(2),  
@PageNumber INT,  
@ProductsPerPage INT,  
@HowManyProducts INT OUTPUT  
)  

AS  

-- Declare a new @Products TABLE variable.  
DECLARE @Products TABLE  
(  
RowNumber INT,  
prodid VARCHAR(40),  
description VARCHAR(2000)  
)  

-- Populate the @Product TABLE variable with the selected Products.  
INSERT INTO @Products  

SELECT  

ROW_NUMBER() OVER (ORDER BY cds_atr.prodid),  
cds_atr.prodid,  
cds_stdnee.description  

FROM cds_stdnee  

JOIN cds_atr  
ON (cds_stdnee.prodid = cds_atr.prodid)  

WHERE cds_atr.catid = @CatID  

-- Return the Total Number of Products using an OUTPUT variable.  
SELECT @HowManyProducts = COUNT(prodid) FROM @Products  

-- Extract the Requested Page of Products.  
SELECT DISTINCT prodid, description  

FROM @Products  

WHERE RowNumber > (@PageNumber - 1) * @ProductsPerPage  
  AND RowNumber <= @PageNumber * @ProductsPerPage

如果它只返回一行,很可能只有一行要返回。添加一个SELECT * FROM @Products并查看那里有哪些行。特别是,查看行号。
