排序EAV數據庫

Question

我試圖放置一個EAV表，我無法讓它工作。 我得到的結果，但我無法得到它排序。

這是我的查詢：

SELECT 
    formFields.uid, 
    formFields.formId, 
    formFields.postId, 
    formFields.name, 
    formFields.value 
FROM formFields 
INNER JOIN formFields aux 
    ON (aux.name = "date") 
WHERE 
    formFields.formId = "1789" 
    AND formFields.deleted = 0 
    AND formFields.hidden = 0 
ORDER BY aux.value DESC 

這是表：

uid formId postId name value 
1 1789 1 title example title #1 
2 1789 1 date 1341091600 
3 1789 2 title example title #2 
4 1789 2 date 1341092300 
5 1789 3 title example title #3 
6 1789 3 date 1341081200 

這是我需要的結果：

uid formId postId name value 
3 1789 2 title example title #2 
4 1789 2 date 1341092300 
1 1789 1 title example title #1 
2 1789 1 date 1341091600 
5 1789 3 title example title #3 
6 1789 3 date 1341081200 

結果是由值排序在名稱欄中有日期
（值僅爲示例）

Answer 1

如果你想ORDER BY的date值，那麼你可以使用這樣的事情：

SELECT 
    formFields.uid, 
    formFields.formId, 
    formFields.postId, 
    formFields.name, 
    formFields.value 
    FROM formFields 
INNER JOIN formFields aux 
    ON (aux.name = "date") 
WHERE formFields.formId = "1789" 
    AND formFields.deleted = 0 
    AND formFields.hidden = 0 
ORDER BY case when formFields.name = 'date' then 0 else 1 end

SELECT  formFields.uid,  
     formFields.formId,  
     formFields.postId, 
     formFields.name, 
    formFields.value 
FROM formFields tx_gcgluteusfeed_formFields 
INNER JOIN formFields b 
     ON formFields.postId = b.postId 
INNER JOIN formFields c 
     ON (c.name = "date") 
WHERE ormFields.formId = "1789" 
     AND formFields.deleted = 0 
     AND formFields.hidden = 0 
ORDER BY 1 DESC
