两个sql server 2000的通用分页存储过程

第一个支持唯一主键，第二支持多主键，测试过，效率一般

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',
'col5>0 and col7<9','pk1 asc,pk2 asc,pk3 asc',2000000,10,89,
