Postgres Query Parent base on association child












0















The Scenario




  1. Client has zero or many assessments

  2. Assessment has zero or many assessment_domains

  3. Assessment has 12 assessment_domains

  4. assessment_domain has field score(integer) value (1 to 4)



SELECT "clients".* FROM "clients" INNER JOIN "assessments" ON "assessments"."client_id" = "clients"."id" INNER JOIN "assessment_domains" ON "assessment_domains"."assessment_id" = "assessments"."id" WHERE "assessment_domains"."score" = 2;




So I expect to have only clients who have all assessment_domains.score = 2. Something was wrong with my query?
