この質問があります。私が使用するこのクエリがあります：

"SELECT  formas.*,
        SMS_SERVISI.IDTICKET,
        SMS_SERVISI.MBYLLUR,
        SMS_SERVISI.time_added,
        servis_furnitor.id_servis,
        servis_furnitor.furnitori,
        servis_furnitor.kohezgjatja,
               referenca.id_referenca,
        referenca.shenime

FROM formas
LEFT JOIN servis_furnitor
        ON formas.furnitori = servis_furnitor.id_servis
LEFT JOIN SMS_SERVISI
        ON formas.ID = SMS_SERVISI.IDTICKET
        AND formas.sektori_pergjegjes ='A'
        LEFT JOIN referenca
        ON formas.ID = referenca.id_referenca  "

私の問題は、条件の一部がAND formas.sektori_pergjegjes ='A' 実行されないということです。置き忘れなどをしたのかもしれませんが、うまくいきません。

こちらをご覧ください。ありがとう

条件AND formas.sektori_pergjegjes ='A'は結合条件の一部であるため、結合結果に対してのみ実行されます。すべてのデータをフィルターに準拠させる場合は、データをwhere句に移動する必要があります。

SELECT  formas.*,
        SMS_SERVISI.IDTICKET,
        SMS_SERVISI.MBYLLUR,
        SMS_SERVISI.time_added,
        servis_furnitor.id_servis,
        servis_furnitor.furnitori,
        servis_furnitor.kohezgjatja,
        referenca.id_referenca,
        referenca.shenime    
FROM formas
LEFT JOIN servis_furnitor
        ON formas.furnitori = servis_furnitor.id_servis
LEFT JOIN SMS_SERVISI
        ON formas.ID = SMS_SERVISI.IDTICKET
LEFT JOIN referenca
        ON formas.ID = referenca.id_referenca
WHERE formas.sektori_pergjegjes ='A'

and条件をwhereとして配置し、それが解決するかどうかを確認します

"SELECT  formas.*,
        SMS_SERVISI.IDTICKET,
        SMS_SERVISI.MBYLLUR,
        SMS_SERVISI.time_added,
        servis_furnitor.id_servis,
        servis_furnitor.furnitori,
        servis_furnitor.kohezgjatja,
               referenca.id_referenca,
        referenca.shenime

FROM formas
LEFT JOIN servis_furnitor
        ON formas.furnitori = servis_furnitor.id_servis
LEFT JOIN SMS_SERVISI
        ON formas.ID = SMS_SERVISI.IDTICKET

        LEFT JOIN referenca
        ON formas.ID = referenca.id_referenca 
 WHERE formas.sektori_pergjegjes ='A' "

    ON formas.ID = SMS_SERVISI.IDTICKET
LEFT JOIN referenca
    ON formas.ID = referenca.id_referenca  
WHERE formas.sektori_pergjegjes ='A'"
