想把結果的日期給弄成橫排。所以就這樣弄了。
select t.DXID AS 姓名,
sum(decode(t.CJSJ,'2019-05-01',RCYL,null))怪事,
sum(decode(t.CJSJ,'2019-05-02',RCYL,null))數字,
sum(decode(t.CJSJ,'2019-05-03',RCYL,null))為啥
from JCCDJNHRB t group by DXID order by DXID desc
再加一句
SELECT a.dxid,
sum(decode(a.CJSJ,'2019-05-01',RCYL,null))怪事,
sum(decode(a.CJSJ,'2019-05-02',RCYL,null))數字,
sum(decode(a.CJSJ,'2019-05-03',RCYL,null))為啥
from JCCDJNHRB a, dbaa061 b, DBBA021 c
where cjsj <= to_date('2019-05-03', 'yyyy-mm-dd ')
and cjsj >= to_date('2019-05-01', 'yyyy-mm-dd ')
and a.DWDM = '011101'
and a.dwdm = b.dwdm
and a.dxid = c.dxid
group by a.dxid order by a.dxid asc
