1、创建存储过程,语句如下:

    @Where VARCHAR(2000),        --查询条件 不含'where'字符,如id>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

2、SQL Server 中调用测试代码

--执行存储过程
declare @TotalCount int,
        @TotalPageCount int
exec P_viewPage 'T_Module','*','ModuleID','','',1,0,10,1,@TotalCount output,@TotalPageCount output
Select @TotalCount,@TotalPageCount;

asp.net 代码实现:
