SELECT with two AND條件

-2

我想在MySQL中使用SELECT語句，並且有兩個AND條件。這是我的表和插入，然後是選擇語句。我沒有從select語句中得到任何結果。SELECT with two AND條件

SELECT distinct post_id FROM indextable as i WHERE (i.key ='price' AND i.value BETWEEN 12 AND 1000) AND (i.key ='year' AND i.value=2012)

注意：當我只使用第一個條件或只使用第二個條件時，我得到一個結果。

我要執行這樣的查詢：

SELECT distinct post_id 
FROM indextable as i 
WHERE (i.key ='price' AND i.value BETWEEN 12 AND 1000) 
    AND (i.key ='year' AND i.value=2012) 
    AND (i.key ='body_condition' AND i.value=1) 
    AND (i.key ='mechanical_condition' AND i.value=6) 
    AND (i.key ='seller_type' AND i.value=11) 
    AND (i.key ='body_type' AND i.value=347) 
    AND (i.key ='doors' AND i.value=360) 
    AND (i.key ='no_of_cylinders' AND i.value=365) 
    AND (i.key ='color' AND i.value=707) 
    AND (i.key ='transmission_type' AND i.value=377) 
    AND (i.key ='horsepower' AND i.value=387) 
    AND (i.key ='warranty' AND i.value=725) 
    AND (i.key ='fuel_type' AND i.value=380)

按設計工作，不是嗎？沒有一次記錄符合兩個條件。您可能正在尋找'OR'而不是'AND'？ –

@ user1431393我如何說你需要改變......）和（...爲OR，所以它會是（....）或（....）或（...）或.. ... – jcho360

.... WHERE (i.key ='price' AND i.value BETWEEN 12 AND 1000) AND 
      (i.key ='year' AND i.value=2012)

意味着i.key的值必須是「價格」和「年」同一排。這是不可能的，因此沒有結果！

更改爲

.... WHERE (i.key ='price' AND i.value BETWEEN 12 AND 1000) OR 
      (i.key ='year' AND i.value=2012)

我想要所有的廣告都來自數據庫，價格在12到1000之間，年份是2012年...你建議我使用或者是insted和？很好的thnx對你來說 –

那是因爲你的病情它是錯的。

SELECT distinct post_id FROM indextable as i 
WHERE (i.key ='price' AND i.value BETWEEN 12 AND 1000) 
AND (i.key ='year' AND i.value=2012)

這是相同的使用

SELECT distinct post_id FROM indextable as i 
WHERE i.key ='price' AND i.value BETWEEN 12 AND 1000 
AND i.key ='year' AND i.value=2012

我想嘗試做的是

SELECT distinct post_id FROM indextable as i 
WHERE (i.key ='price' AND i.value BETWEEN 12 AND 1000) 
OR (i.key ='year' AND i.value=2012)

編輯：你的意思，你就沒有這個結果嗎？我複製你的表，並做了查詢，它的工作原理。

我沒有任何結果，當我使用這個陳述： –

@ user1431393更新了答案 – jcho360

我用「和」，以便我沒有任何結果，但是當我使用或者我喜歡你的結果時，我想或者proplem將被解決：）謝謝 –
