Get all object_id's where term_taxonomy_id is IN(1,2) AND NO IN(3)

Hello,

how can i get all object_id’s from the wp_term_relationships where term_taxonomy_id is IN(1,2) AND NOT IN(3)

Means…

object_id	term_taxonomy_id	term_order
1		1			0
1		2			0
1		3			0
2		1			0
2		2			0
3		1			0
3		2			0
4		1			0
5		1			0
5		3			0

I need the get object_id 2 and 3

SELECT c1.object_id
FROM wp_term_relationships AS c1
INNER JOIN wp_term_relationships AS c2 ON c1.object_id = c2.object_id
WHERE c1.term_taxonomy_id = 1
AND c2.term_taxonomy_id = 2

Works, but i don’t know how to exclude term_taxonomy_id 3

Thanks!
