edit 2:

enter image description here

here sql query returning desired result using sub select:

select [users].memberid,   [users].firstname,   [users].lastname,   thislog.dateofchange,   statuslist1.title oldstatus,   statuslist2.title newstatus,   (select top 1 datediff(hour,lastlog.dateofchange,thislog.dateofchange)   [dbo].[statuslog] lastlog lastlog.dateofchange<thislog.dateofchange   order dateofchange desc ) hourssincelastchange   [dbo].[statuslog] thislog   inner join [users] on [users].iduser=thislog.iduser   inner join statuslist statuslist1 on statuslist1.idstatus=thislog.oldstatus   inner join statuslist statuslist2 on statuslist2.idstatus=thislog.newstatus   order dateofchange desc

hopefully got column , table names correct.
