我有問題，試圖重新以下查詢：無法重新創建SQL查詢與學說
select *
from acme_opties_relaties as r
inner join acme_options as o on o.id = r.id_a
inner join acme_option_subgroup as osg on osg.option_id = o.id
where osg.subgroup_id in (309, 303, 306, 300)
and o.id <> 47086
and r.soort = 2
and o.project_id = 140018
我所得到的是下面的查詢：
SELECT t0_.id_a AS id_a_17, t0_.id_b AS id_b_18,
t0_.soort AS soort_0, t1_.id AS id_1, t1_.external_id AS external_id_2, t1_.external_ref AS external_ref_3, t1_.`name`
AS name_4, t1_.name_sales AS name_sales_5, t1_.price AS price_6, t1_.warranty AS warranty_7, t1_.material AS material_8, t1_.no_option
AS no_option_9, t1_.print AS print_10, t1_.text_warranty AS text_warranty_11, t1_.text_technical AS text_technical_12, t1_.text_sales AS text_sales_13, t1_.`group`
AS group_14, t1_.created AS created_15, t1_.updated AS updated_16, t1_.project_id AS project_id_19
FROM acme_opties_relaties t0_
INNER JOIN acme_options t1_ ON
(t1_.id <> 47086 AND t0_.soort = 2 AND EXISTS
(SELECT 1 FROM acme_option_subgroup t2_ INNER JOIN acme_subgroep t3_ ON t2_.subgroup_id = t3_.id WHERE t2_.option_id = t1_.id AND t3_.id IN (309, 303, 306, 300))
AND t1_.project_id = 140018)
任何指針/方向，將不勝感激。

問題是關係和選項之間的連接不上r.option.id_a = option.id但在r.option.id_a <> X，它應該加入的ID和在哪裏適用<> X
