* 作 用：数据分页(完整SQL分页存储过程（支持多表联接）)
* 作 者：齐李平
* 创建日期：2009-03-23
* 使用说明：
1、单表调用方法：EXEC proc_DataPagination @tblName = 'ipa',@fldName = '*',@pageSize =50,@page = 6789,@fldSort = '',@Sort = 1,@strCondition = '',@ID = 'id',@Dist = 0,@pageCount = null,@Counts = NULL
2、多表调用方法：EXEC proc_DataPagination @tblName = 'Info LEFT JOIN InfoType it ON it.typeid=Info.tid',@fldName = 'info.*,it.tname',@pageSize =50,@page = 1806,@fldSort = '',@Sort = 0,@strCondition = '',@ID = 'id',@Dist = 0, @pageCount = null,@Counts = NULL
* 多表联合查询使用需注意：1、多表中的主键字段不能为相同的名称。2、多表中不能允许具有相同名称的字段，如果存在相同名称的字段你可以使用AS重命名
