谁能帮帮我。
在SQL Server2005中,我有一个用于数据分页的存储过程(见下文)。该存储过程的目的是返回特定类别(CatID)的一页产品(prodid、描述)。
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 它只返回一(1)行,即使有很多产品:
@HowManyProducts: 10034我有一个类似的存储过程,它对较小的数据集工作得很好。我是不是达到了某种极限?
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发布于 2009-03-31 17:23:34
如果它只返回一行,那么很可能只返回一行。添加一个SELECT * FROM @Products并查看其中有哪些行。特别要注意行号。
