如何组合这两个查询

SELECT
    ART_ARTICLE_NR,
    SUP_BRAND,
    DES_TEXTS.TEX_TEXT AS ART_COMPLETE_DES_TEXT,
    DES_TEXTS2.TEX_TEXT AS ART_STATUS_TEXT
FROM ARTICLES
    INNER JOIN DESIGNATIONS ON DESIGNATIONS.DES_ID = ART_COMPLETE_DES_ID
    INNER JOIN DES_TEXTS ON DES_TEXTS.TEX_ID = DESIGNATIONS.DES_TEX_ID
    INNER JOIN SUPPLIERS ON SUP_ID = ART_SUP_ID
    INNER JOIN ART_COUNTRY_SPECIFICS ON ACS_ART_ID = ART_ID
    INNER JOIN DESIGNATIONS 
        AS DESIGNATIONS2 ON DESIGNATIONS2.DES_ID = ACS_KV_STATUS_DES_ID
    INNER JOIN DES_TEXTS
        AS DES_TEXTS2 ON DES_TEXTS2.TEX_ID = DESIGNATIONS2.DES_TEX_ID
WHERE
    ART_ID IN ( 
                52277
        ) AND
    DESIGNATIONS.DES_LNG_ID = 19 AND
    DESIGNATIONS2.DES_LNG_ID = 19;

我想这可能行得通。请注意，这是未测试的（尤其是您忽略了向我们提供表的布局），我不得不猜测

你不能在你的表示层中组合它们吗？我想大多数人更喜欢用小写字母和较短的相关名称来阅读。我认为这些查询可以合并，但我懒得删除它们。您使用的是什么RDBMS？对于PHP，我假设是mySQL，但我希望不是（因为CTE在这里很有用…）。尽管如此，您可能希望视图包装

指定

和

Des_文本

。
