Mysql multiple conditions on same column

Question

My table categories_article looks like this :

I want to return all articles which have categorie 1 and 11 and 13 and 22. I am trying to do it like this :

select * from categories_article where categorie in(1,11,13,22)

But the request return article 13, and in this example the article 13 doesn't have categorie 22.

Please somebody help me thank you.

Answer 1

You will want to use an EXISTS statement to make sure that each of those categories are found for the articles. There's bound to be a better way to do this, but here's a solution:

Select  *
From    categories_article  A
Where   Exists 
(
    Select  *
    From    categories_article  B
    Where   A.article = B.article
    And     B.categorie = 1
)
And     Exists 
(
    Select  *
    From    categories_article  B
    Where   A.article = B.article
    And     B.categorie = 11
)
And     Exists 
(
    Select  *
    From    categories_article  B
    Where   A.article = B.article
    And     B.categorie = 13
)
And     Exists 
(
    Select  *
    From    categories_article  B
    Where   A.article = B.article
    And     B.categorie = 22
)

Answer 2

You can do what you want with a group by and having clause:

select article
from categories_article
where categorie in (1, 11, 13, 22)
group by article
having count(*) = 4;

If you can have duplicates in the table, use count(distinct categorie) = 4 .
