Question

I have this SQL table :

name  | id_photo
================
word1 | 38    
word2 | 38
word7 | 39
word1 | 31
word2 | 31

And I would like to research all the id_photo such as name = word1 AND name = word2
for example is this case I would like to have as a return 38,31

Can somebody suggest a solution?

Answer 1

SELECT ID_PHOTO
FROM tableNAME
WHERE name IN ('word1','word2')
GROUP BY ID_PHOTO
HAVING COUNT(*) = 2

if unique key was not specified on name for each id_photo, use distinct inside COUNT

SELECT ID_PHOTO
FROM tableNAME
WHERE name IN ('word1','word2')
GROUP BY ID_PHOTO
HAVING COUNT(DISTINCT name) = 2
