多列的SQL DISTINCT查询 [英] SQL DISTINCT query on Multiple Columns

问题描述

我有一个这样的表:

Artist   Image   Title

Smith    2       Country
Smith    5       Town
Doyle    21      Cat
Lawlor   24      Ball
Jones    8       Cheese
Jones    12      Bread
Jones    15      Butter

我想设置一个DISTINCT查询以一次返回Artist，这与返回哪条记录无关.这就是我要寻找的:

And I want to set up a DISTINCT Query to return the Artist once - doesn't matter which of the records are returned. This is what I'm looking for:

Artist   Image   Title
Smith    2       Country
Doyle    21      Cat
Lawlor   24      Ball
Jones    8       Cheese

我在MS Access数据库上使用ASP.

I am using ASP on a MS Access database.

非常感谢您的帮助.

推荐答案

访问权限具有FIRST和LAST聚合，其中r

Access has FIRSTand LAST aggregates which return the first or last record as it was entered in chronological order

SELECT Artist, FIRST(Image) AS Image, FIRST(Title) AS Title
FROM table
GROUP BY Artist
