Ms access 从以逗号分隔的字符串显示值的表中选择值

这是我的第一篇帖子。。。 我正忙着在Access 2010中编写一个软件。我的SQL还不错，但我在这里有点困惑

我有一张布局如下的桌子

ID = AutoNumber, 
Category = Text, 
SubCategory = Text, 
Grades = Text.

以及以下数据

ID  Category    SubCategory   Grades
2   Behaviour   Good          RRR,RR,R,1,2,3,4,5,6,7,8,9,10,11,12
3   Behaviour   Not so Good   RRR,RR,R,1,2,3,4,5,6,7,8,9,10,11,12
4   Health      Doctor Note   RRR,RR,R,1,2,3,4,5,6,7,8,9,10,11,12
5   Social      Peer Pressure   
6   Academics   General Academic Knowledge      1,2,3
7   Academics   Additional Academic Knowledge   1,2,3
8   Gross Motor Skills  Kicks a ball that is moving towards him or her. 
9   Gross Motor Skills  Hops and jumps while in motion  R
10  Gross Motor Skills  Skips   RR
11  Gross Motor Skills  Gallops RR
12  Gross Motor Skills  Jumps forward 10 times  RR
13  Gross Motor Skills  Catches a small bounced ball    RR
14  Gross Motor Skills  Turns somersault    RR
15  Gross Motor Skills  Alternates feet walking up or down stairs   RR`

我正在尝试创建一个查询，其中我选择了eg

SELECT SubCategory from CATEGORY WHERE GRADES LIKE R

它应该会回来

Good
Not so Good
Doctors Note
Peer Pressure
Hops jumps and Skips

显然，如果我需要RRR或1、2或5级，它应该根据需要选择

请任何人帮忙。 谢谢

您可以通过操作员

这样做：

SELECT SubCategory 
FROM CATEGORY 
WHERE ',' + GRADES + ',' LIKE '*,R,*'

或者，如果希望查询的值
'R'
单独作为参数：

SELECT SubCategory 
FROM CATEGORY 
WHERE ',' + GRADES + ',' LIKE '*,' + 'R' + ',*'

我是如此接近。。。我使用了WHERE'，GRADES&'，LIKE'，R'，：）这不起作用。。。谢谢你……你错过了外卡。
