SQL连接列是另一个的子集

Question

假设有以下表格：

Table A
[Description]
Some Apples are Green
Many Bananas are Yellow
Carrots are Orange

Table B
[Color]
Apples
Bananas
Carrots

我想inner join这些表B.[Color]是A.[Description]

的子集

结果将是

[Description]            [Color]
Some Apples are Green    Green
Many Bananas are Yellow  Yellow
Carrots are Orange       Orange

Answer 1

Demo Here

这不涉及类似条件

select dataa,b.colorname from #temp t
cross apply
(select  replace(t.dataa,colorname,'') as rplc,colorname
from #colors)b
where dataa<>rplc

Answer 2

虽然TheGameiswar的解决方案非常酷且效率更高 ....这是针对一小部分数据的另一种更简单的解决方案。

select * from
#A
inner join  #B
on [description] like '%'+color+'%'

Answer 3

我会选择最简单的解决方案，除非性能可能是个问题：

tsc

注意我认为描述以颜色结束。如果情况并非总是如此，则需要在最后添加另一个％。
