database - Taking and filtering MYSQL results on another params table -


enter image description here

please me query. want projects_ids, contain params , values of params. when use 1 criteria (not three, image) - works , gaing results!

when use all, think cpu trying record when 3 criterion passed. need projects_ids contains criterion.

my solution @ time self-join. each param create "join" table on "projects_id", , add more statements new tables.

10 params = 10 joins.
