是否可以在同一时间查询具有更多耦合值的表？

Question

查询方面有月 - 年夫妇值。但是表格分列了年份和月份。如果只有一个月 - 年对（例如7-2013）没问题，

SELECT pik.pk_yil AS pkYil, 
       pik.pk_ay As pkAy, 
       krm.kurum_adi AS krmAdi, 
       ilc.ilac_adi AS ilcAdi, 
       pik.ilac_parti_no AS ilcPN, 
       pik.ilac_skt AS ilcSKT
FROM piyasa_kontrol pik
     LEFT JOIN kurum_adlari krm ON pik.pk_il=krm.id 
     LEFT JOIN ilaclar ilc ON pik.ilac_id=ilc.id 
WHERE pk_il=
    (
      SELECT evrak_gonderen 
      FROM evraklar 
      WHERE id=124 OR gelen_evrak_etakip=124
    )
    AND pik.pk_yil = 2012 
    AND pk_ay = 6

如果有多对像“7-2013,8-2013,3-2011”，我该如何设置查询？月和年也已经结合查询逻辑。 语言是php，db是mysql。

您是否只是在寻找or？

WHERE pk_il = (SELECT evrak_gonderen 
               FROM evraklar 
               WHERE id=124 OR gelen_evrak_etakip=124
              ) AND
     ((pik.pk_yil=2012 AND pk_ay=6) OR
      (pik.pk_yil=2013 AND pk_ay=7) OR
      (pik.pk_yil=2013 AND pk_ay=8) OR
      (pik.pk_yil=2011 AND pk_ay=3)
     )
