从MySQL / MariaDB中的多个连接中选择具有最低值的元素
如何选择分组依据和多个联接的某些数据集？我读过sub queries or left join approaches，但遗憾的是我无法将其与其他需求结合起来。我的问题是，我从其他客户端获得条目或条目没有2个表之间的完整关系。或左侧的右侧条目，但右侧的值不是最右侧的条目。甚至完全不同的数据，我无法理解为什么。
预期结果
例如，对于price_consumer和model_id以及client_id = 1000的每个模型（country_id = 1），我需要最便宜的（pricelist_id = 20）电机。最相关的数据在表cc_pricelist_elements中。此处col fk_table是相关的，因为只有行具有值 motors 才有意义。 cc_pricelist_elements中没有相应条目的模型不应该是结果的一部分。
同时，需要cc_models表中相应模型的名称。
结果集（在下面给出的数据中）看起来像：
cc_models.name | cc_pricelist_elements.price_consumer
---------------|-------------------------------------
Model 2016 | 150
当然，每个客户可能会有更多型号（n：1），每个型号可能有很多电机（
数据库结构和样本数据
编辑： sqlfiddle，简化了表格结构并减少了数据。
我在这里放了一些表，因为我不确定它们是否是查询所必需的，因为它们彼此部分相关。

方法
这是我到目前为止提出的（最好的方法），但结果远远不能满足需要。
SELECT
ccm.model_id, ccm.name, ccpe.price_consumer
FROM
cc_models ccm
INNER JOIN
cc_meta_lines_models cclm ON
cclm.model_id = ccm.model_id
INNER JOIN
cc_pricelist_elements ccpe ON
ccpe.client_id = 1000 AND
ccpe.fk_table = 'motors' AND
ccpe.country_id = 1 AND
ccpe.pricelist_id = 20
LEFT JOIN
cc_pricelist_elements ccpe2 ON
ccpe2.pricelist_element_id = ccpe.pricelist_element_id AND
ccpe.price_consumer < ccpe2.price_consumer
WHERE
ccm.client_id = 1000 AND
ccpe2.pricelist_element_id IS NULL
ORDER BY
ccm.name
