Sql语句：
select row_num,User_Name,User_Email,User_Phone,To_UserName,To_Context from(SELECT ROW_NUMBER() OVER ( ORDER BY To_Date desc)as row_num,User_Name,User_Email,User_Phone,To_UserName,To_Context from TChristmaxWish where Is_Del=0 )as newTable where row_num between @intStrIndex and @intEndIndex;
select count(id) from TChristmaxWish where Is_Del=0
