sqlserver 存储过程分页代码，
前端之家小编觉得挺不错的，现在分享给大家，也给大家做个参考。
<div class="codetitle"><a style="CURSOR: pointer" data="62853" class="copybut" id="copybut62853" onclick="doCopy('code62853')"> 代码如下:

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
