为此数据选择不同

Question

谁能帮助我吗？我想用这些数据选择不同的东西：

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 ...

我想选择不同的结果将是这样的：

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 ...

感谢＆＃39; s谁回答了我的问题。

Answer 1

如果我理解正确，您需要在日期列中group by和min

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

Answer 2

检查一下。

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