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

联合主键的：

CREATE PROC P_public_ViewPage

/**//*

no_mIss 通用分页存储过程 2007.3.1 QQ:34813284

适用于联合主键/单主键/存在能确定唯一行列/存在能确定唯一行的多列 (用英文,隔开)

调用：

第一页查询时返回总记录和总页数及第一页记录：

EXECUTE P_public_ViewPage_per 'TableName','col1,col2,col3,col4','pk1,pk2,pk3',

'col5>0 and col7<9','pk1 asc,pk2 asc,pk3 asc',0,10,1,

@TotalCount OUTPUT,@TotalPageCount OUTPUT

其它页调用，比如第89页(假设第一页查询时返回总记录为2000000)：

EXECUTE P_public_ViewPage_per 'TableName','col1,col2,col3,col4','pk1,pk2,pk3',
