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,

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',
