Question

帮助合并两个sql查询（TECDOC）。

显示名称和部件号;
显示技术参数的详细信息。

如何组合这两个查询？

我认为这可能有效。请注意，这是不测试（特别是因为你忽略了为我们提供表格的布局），而且我必须猜测articles是怎么回事与article_criteria相关联。

SELECT Articles.art_article_nr, Suppliers.sup_brand
       Article_Designations.text, Country_Specific_Designations.text,
       Article_Criteria_Designations.value,
       Article_Criteria_Designations.text
FROM Articles
JOIN (SELECT Designations.des_id, Des_Texts.tex_text as text
      FROM Designations
      JOIN Des_Texts
      ON Des_Texts.tex_id = Designations.des_tex_id
      AND Designations.des_lng_id = 19) as Article_Designations
ON Article_Designations.des_id = Articles.art_complete_des_id

JOIN Suppliers
ON Suppliers.sup_id = Articles.art_sup_id

JOIN Art_Country_Specific
ON Art_Country_Specific.acs_art_id = Articles.art_id
JOIN (SELECT Designations.des_id, Des_Texts.tex_text as text
      FROM Designations
      JOIN Des_Texts
      ON Des_Texts.tex_id = Designations.des_tex_id
      AND Designations.des_lng_id = 19) as Country_Specific_Designations
ON Country_Specific_Designations.des_id = Art_Country_Specific.acs_kv_status_des_id

LEFT JOIN (SELECT Article_Criteria.acr_art_id,
           COALESCE(Art_Cri_Designations.text, Article_Criteria.acr_value) as value,
           Criteria_Designations.text
           FROM Article_Criteria
           LEFT JOIN (SELECT Designations.des_id, Des_Texts.tex_text as text
                      FROM Designations
                      JOIN Des_Texts
                      ON Des_Texts.tex_id = Designations.des_tex_id
                      AND Designations.des_lng_id = 19) as Art_Cri_Designations
           ON Art_Cri_Designations.des_id = Article_Criteria.acr_kv_des_id
           LEFT JOIN (SELECT Criteria.cri_id, Des_Texts.tex_text as text
                      FROM Criteria
                      JOIN Designations
                      ON Designations.des_id = Criteria.cri_des_id
                      JOIN Des_Texts
                      ON Des_Texts.tex_id = Designations.des_tex_id
                      AND Designations.des_lng_id = 19) as Criteria_Designations
           ON Criteria_Designations.cri_id = Article_Criteria.acr_cri_id
           ) as Article_Criteria_Designations
ON Article_Criteria_Designations.acr_art_id = Articles.art_id

WHERE Articles.art_id IN (52277)

两个查询的联合
