選擇獨一無二的這種數據

Question

任何人都可以幫助我嗎？我想選擇與此數據明顯：

Code  Name Description Date 
17-0001 A  01-AOE  02/01/2017 
17-0001 A  02-AOE  02/02/2017 
17-0001 B  01-AOE  02/01/2017 
17-0001 B  02-AOE  02/03/2017 
etc ... 

我要選擇不同的結果將是這樣的：

Code  Name Date 
17-0001 A  02/01/2017 ---> Only The First Date And Not Show The Fld Desc 
17-0001 B  02/01/2017 
etc ... 

感謝對誰的回答我的問題。

Answer 1

如果我理解正確的，你的日期列

select code, name, min(date) 
from t 
group by code, name; 

Answer 2

入住這需要一個group by和min。

select code, name, min(date) as date 
from tablename 
group by code, name;
