在下面的屏幕快照中,我的输出以这种方式可见,但是如果他们使用许多代码,我确实需要在一行中输出。
我目前有这样的输出:
originalID datein Dateout CameID code code2 code3

但是我需要将其分组,例如,如果一个originalID具有许多代码,则应将其分组为包含OriginalID,date in,dateout,cameID,code,code2,code3的一行
我需要输出看起来像这样:
originalID datein Dateout CameID code code2 code3

答案 0 :(得分:0)
我认为您只需要汇总:
select originalId, datein, dateout, camelid, min(code), min(code2), min(code3)
from t
group by originalId, datein, dateout, camelid
