不要忘了你曾经会写sql的

UPDATE

update gps_percent_201605_copy s set 
newtran=(select DISTINCT v.tran_new from vehicle v where v.vincode=s.vin and left(v.areacode,2)=left(s.accesscode,2)  and v.color=s.color  LIMIT 0,1 ), 
enter=(select DISTINCT v.enterid from vehicle v where v.vincode=s.vin and left(v.areacode,2)=left(s.accesscode,2)  and v.color=s.color  LIMIT 0,1 ) 
where newtran is null

聚合函数+GROUP BY

select b.cname areacode,a.tran,a.dateday,SUM(a.p90) p90,SUM(a.pall) pall,SUM(a.p90)/SUM(a.pall) lv from

area b where a.areacode=b.city GROUP BY areacode,tran ORDER BY lv DESC

按字段去重，利用伪列ROWID
