Question

我希望两个将这两个查询合并为一个查询

SELECT p.NAMA_PT AS PT_PEMBERI
FROM perusahaan p
LEFT JOIN penerima_waralaba pw ON pw.ID_PERUSAHAAN = p.ID
LEFT JOIN outlet o ON o.ID_PENERIMA_WARALABA = pw.ID
LEFT JOIN nomor_logo nl ON nl.ID = o.NOMOR_LOGO_WARALABA
WHERE nl.NOMOR_LOGO = 'WI-0010205-610'

还有这个

SELECT pw.NAMA_PT AS PT_PENERIMA
FROM penerima_waralaba pw
LEFT JOIN outlet o ON o.ID_PENERIMA_WARALABA = pw.ID
LEFT JOIN nomor_logo nl ON nl.ID = o.NOMOR_LOGO_WARALABA
WHERE nl.NOMOR_LOGO = 'WI-0010205-610'

谢谢

Answer 1

您可以在语句中使用派生表。例如

从（选择...）中选择X，Y作为表1联接（选择...）作为表2等。

Answer 2

如果两个查询都可以，只需使用join，然后下面的方法就可以使用

select t1.PT_PEMBERI,t2.PT_PENERIMA from
(SELECT nl.ID, p.NAMA_PT AS PT_PEMBERI
    FROM perusahaan p
    LEFT JOIN penerima_waralaba pw ON pw.ID_PERUSAHAAN = p.ID
    LEFT JOIN outlet o ON o.ID_PENERIMA_WARALABA = pw.ID
    LEFT JOIN nomor_logo nl ON nl.ID = o.NOMOR_LOGO_WARALABA
    WHERE nl.NOMOR_LOGO = 'WI-0010205-610'
    )t1
  inner join
  (
    SELECT nl.ID,pw.NAMA_PT AS PT_PENERIMA
    FROM penerima_waralaba pw
    LEFT JOIN outlet o ON o.ID_PENERIMA_WARALABA = pw.ID
    LEFT JOIN nomor_logo nl ON nl.ID = o.NOMOR_LOGO_WARALABA
    WHERE nl.NOMOR_LOGO = 'WI-0010205-610
    )t2 on t1.ID=t2.ID
