如何获得每个帐户的一个记录？

Question

我有一个查询：

select memo_account ,flags_3,SUFFIX,date 
    FROM MEMO 
    left join daily on daily.ACCOUNT= memo.memo_account 
    where flags_3 = 1 and suffix in (08,00) 
    and memo_number =3333 

其即时得到这两个表中的帐户。 我得到的结果在两个行后面的每个帐户基础是00或08.

我怎么会得到它，我可以得到的帐户只显示一次 和后缀取决于如果是00或08在一排？

例如：

memo_account | suffix_00 | suffix_08 |日期

Answer 1

select memo_account, 
     max(case when SUFFIX = '00' then '00' else null end) as suff00, 
     max(case when SUFFIX = '08' then '08' else null end) as suff08, 
     date 
    FROM MEMO 
    left join daily on daily.ACCOUNT= memo.memo_account 
    where flag_3 = 1 and suffix in (08,00) 
    and memo_number =3333 
group by memo_account, date 

你有个约会也，所以你会得到一些额外的行如果同一memo_account
