mysql - 2 つの AND 条件による SELECT

Question

SELECTMySQL で 2 つの条件を持つステートメントを使用したいと考えていますAND。これは私のテーブルと挿入で、その後に select ステートメントが続きます。select ステートメントから結果が得られません。

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: 最初の条件のみ、または 2 番目の条件のみを使用すると、結果が得られます。

次のようなクエリを実行したい：

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 )

それはあなたの状態が間違っているからです。

    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 )

それは使用するのと同じです

    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

あなたがやろうとしていることは

    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 )

編集：あなたがこの結果を持っていないということはどういう意味ですか？私はあなたのテーブルをコピーしてクエリを実行しました、そしてそれは動作します。

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

つまり、i.keyの値は同じ行の「price」と「year」である必要があります。それは不可能なので、結果はありません！

への変更

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