这是经常用的一个分页存储过程 希望大家指点不足
复制代码 代码如下:
USE [a6756475746]
GO
/****** Object: StoredProcedure [dbo].[tbl_order_SearchWhereAndPage] Script Date: 11/01/2011 09:37:39 ******/

ALTER PROCEDURE [dbo].[tbl_order_SearchWhereAndPage]

@minDate datetime,
@maxDate datetime
AS
begin
DECLARE @PageLower int
set @PageLower=@PageSize * @PageIndex
DECLARE @PageUpper int
set @PageUpper= @PageLower + @PageSize - 1

DECLARE @SearchSQL nvarchar(4000)
set @SearchSQL='SELECT * ,( ROW_NUMBER() OVER (ORDER BY [ID] DESC) -1 ) AS RowNumber FROM tbl_order WHERE (1=1) '
DECLARE @SearchSQLCount nvarchar(4000)
set @SearchSQLCount='SELECT @count=Count(*) FROM tbl_order WHERE (1=1) '
declare @Result [varchar](5000)
set @Result=''

if @minDate>convert(datetime,'1900-1-2')
begin

end

begin
set @Result=@Result+' and oDeliveryDate <= '''+convert(varchar(20),dateadd(dd,1,@maxDate))+''''
end
set @SearchSQLCount=@SearchSQLCount+@Result
set @SearchSQL=@SearchSQL+@Result

SET @SearchSQL = 'WITH t AS (' + @SearchSQL +' )
SELECT * FROM t
WHERE [RowNumber] BETWEEN '+ convert(varchar(50),@PageLower) +' AND '+ convert(varchar(50),@PageUpper) + '
ORDER BY RowNumber '

exec (@SearchSQL)

exec sp_executesql @SearchSQLCount ,N'@count as int out' ,@AllCount out

print @SearchSQL

print @AllCount
end
exec (@Result)
