一种方法是使用
distinct：
SELECt distinct "formulation_batch".* FROM "formulation_batch" INNER JOIN "formulation_batch_component" ON "formulation_batch"."id" = "formulation_batch_component"."formulationBatch_id" WHERe "formulation_batch"."project_id" = 1 AND (("formulation_batch_component"."component_id" = 2 OR "formulation_batch_component"."component_id" = 1 ))
