导读:sqlserver 存储过程分页代码并说明了用vc#调用上面的存储过程

<div class="codetitle"><a style="CURSOR: pointer" data="62853" class="copybut" id="copybut62853" onclick="doCopy('code62853')"> 代码如下:<div class="codebody" id="code62853">
declare @TotalCount int
declare @TotalPageCount int
exec P_viewPage_A 'type1','','id','','id asc',1,4,3,@TotalCount output,@TotalPageCount output select from type1
Create PROC P_viewPage_A

nzperfect [no_mIss] 高效通用分页存储过程(双向检索) 2007.5.7 QQ:34813284
敬告:适用于单一主键或存在唯一值列的表或视图
ps:Sql语句为8000字节,调用时请注意传入参数及sql总长度不要超过指定范围
/
@TableName VARCHAR(200),--表名
@FieldList VARCHAR(2000),--显示列名,如果是全部字段则为
@PrimaryKey VARCHAR(100),--单一主键或唯一值键
@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
@TotalPageCount INT OUTPUT --返回总页数
