select m.*, c.NAME as CORP_NAME
from MAIL_LOG as m, CORP as c
where m.SEND_DATE >= '$term_from' and m.SEND_DATE <= '$term_end' ";
与
Select DISTINCT `TO_NAME_F_KANA` from MAIL_LOG group by m.SEND_DATE;
我希望从TO_NAME_F_KANA
作为参考的第一个查询中获取唯一值。

以下查询应该可以解决问题
Select DISTINCT t.`TO_NAME_F_KANA` from
(
select m.*, c.NAME as CORP_NAME
from MAIL_LOG as m, CORP as c
where
m.SEND_DATE >= '$term_from'
and
m.SEND_DATE <= '$term_end'
) t
group by t.SEND_DATE;
