Selecting from two tables and a where condition

Question

I have two tables:

Images:
id | name | width

Extra:
id | width | extra

How can I select all from images and for each row, select 'extra' from the extra table where images.width is <= extra.width?

Eg

Images:
id | name | width
1  | a.jpg| 100
2  | b.jpg| 200
3  | c.jpg| 5
Extra:
id | width | extra
1  | 100   | 'test'
2  | 200   | 'normal'
3  | 50    | 'better'

So:

• a.jpg would have an extra of 'test'.
• b.jpg would have an extra of 'normal'.
• c.jpg would have an extra of 'better.

Answer 1

Try this query

SELECT *
FROM Images JOIN Extra ON Images.width<=Extra.width
