/*********************************************************<br /> * 作 用：数据分页(完整SQL分页存储过程（支持多表联接）)<br /> * 作 者：齐李平<br /> * 创建日期：2009-03-23<br /> * 使用说明：<br /> 1、单表调用方法：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<br /> * 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<br /> *********************************************************/<br /> alter PROCEDURE
