查詢用戶編號為1165的所有數據：

 select * from T_JianKangJC_JianCeSJ where JianCeCSID in (19,7,1,2,20,15) and YongHuID='1165' order by JianCeID desc

 

查詢用戶編號為1165且監測參數為（1,2，7，15,19,20）的最新數據：

 select * from T_JianKangJC_JianCeSJ a where exists(
 select * from (
 select JianCeCSID,max(JianCeSJ) as FTime from T_JianKangJC_JianCeSJ where YongHuID='1165' and JianCeCSID in (19,7,1,2,20,15) group by JianCeCSID ) x
 where x.JianCeCSID=a.JianCeCSID and a.JianCeSJ=x.FTime )
