Sql 查询问题，赢得'；不接受条件

我有这个问题。 我使用以下查询：

"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  "

我的问题是我没有得到条件的部分

和formas.sektori_pergjegjes='A'

没有被执行。也许是我放错地方了，或者别的什么，但我不能让它工作

请看看这个。

谢谢

将和条件放在何处，看看它是否解决

"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' "

尝试：

条件

和formas.sektori_pergjegjes='A'

仅对联接结果执行，因为它是联接条件的一部分。如果希望所有数据都符合筛选条件，则需要将其移动到where子句中

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'

你能提供更多的信息吗？喜欢添加具有期望结果的样本数据吗？

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'
