自己收集比较强大的分页存储过程 推荐
(下面的代码原来我想用折叠的代码的,但是在google里面老是添加不了折叠的代码,所以就整屏的贴出来了,望大家不要见外。)
朋友的比较好的存储过程。优点是:性能非常的高,每次查询都是根据ID查询,每次都是对一半的数据进行分页。缺点是:当有多个排序条件时,分页数据显示会出现问题。(该问题在第二个网友的分页存储过程中有解决的方法)。

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
