首先看下面的代码创建存储过程
1、创建存储过程，语句如下：
10 and len(userid)>9
@Order VARCHAR(1000),--排序 不含'order by'字符，如id asc,userid desc，必须指定asc或desc
--注意当@SortType=3时生效，记住一定要在最后加上主键，否则会让你比较郁闷
@SortType INT,--排序规则 1:正序asc 2:倒序desc 3:多列排序方法
@RecorderCount INT,--记录总数 0:会返回总记录
@PageSize INT,--每页输出的记录数
@PageIndex INT,--当前页数
@TotalCount INT OUTPUT,--记返回总记录
@TotalPageCount INT OUTPUT --返回总页数
AS
SET NOCOUNT ON
IF ISNULL(@TotalCount,'') = '' SET @TotalCount = 0
SET @Order = RTRIM(LTRIM(@Order))
SET @PrimaryKey = RTRIM(LTRIM(@PrimaryKey))
SET @FieldList = REPLACE(RTRIM(LTRIM(@FieldList)),' ','')
WHILE CHARINDEX(',',@Order) > 0 OR CHARINDEX(',@Order) > 0
BEGIN
SET @Order = REPLACE(@Order,')
SET @Order = REPLACE(@Order,')
END
IF ISNULL(@TableName,'') = '' OR ISNULL(@FieldList,'') = ''
OR ISNULL(@PrimaryKey,'') = ''
OR @SortType < 1 OR @SortType >3
OR @RecorderCount < 0 OR @PageSize < 0 OR @PageIndex < 0

END

END
PRINT(@Sql)
EXEC(@Sql)
GO
2、SQL Server 中调用测试代码
declare @TotalCount int,@TotalPageCount int
exec P_viewPage 'T_Module','*','ModuleID','',10,@TotalCount output,@TotalPageCount output
Select @TotalCount,@TotalPageCount;
asp.net 代码实现：
/// 通用分页存储过程
///
///
///
///
///
///
///
///
public static DataSet PageList(string connectionString,string tblName,string strGetFields,string primaryKey,string strWhere,string strOrder,int sortType,int recordCount,int PageSize,int PageIndex,ref int totalCount,ref int totalPageCount)
{
SqlParameter[] parameters ={ new SqlParameter("@TableName ",SqlDbType.VarChar,200),new SqlParameter("@FieldList",2000),new SqlParameter("@PrimaryKey",100),new SqlParameter("@Where",new SqlParameter("@Order",1000),new SqlParameter("@SortType",SqlDbType.Int),new SqlParameter("@RecorderCount",new SqlParameter("@PageSize",new SqlParameter("@PageIndex",new SqlParameter("@TotalCount",new SqlParameter("@TotalPageCount",SqlDbType.Int)};
