我有一个Oracle查询来计算以下百分比：
select to_char(ltrim(round((1 - n / c) * 100) || '%')) as total
from (select count(*) c
from wa_sew_tbl_emp_info
where status = 'Attend'
and shift = case
when to_char(sysdate, 'HH24:MI') >= '07:00'
and to_char(sysdate, 'HH24:MI') <= '19:29' then
'Morning'
when to_char(sysdate, 'HH24:MI') >= '19:30'
and to_char(sysdate, 'HH24:MI') <= '23:59' then
'Night'
when to_char(sysdate, 'HH24:MI') >= '00:00'
and to_char(sysdate, 'HH24:MI') <= '06:59' then
'Night'
end)
,(select count(*) n
from (select s.badgeid_fk
from wa_sew_tbl_emp_info s
,wa_ga_tbl_employees e
where s.badgeid_fk = e.badgeid
and s.status = 'Attend'
and s.shift = case
when to_char(sysdate, 'HH24:MI') >= '07:00'
and to_char(sysdate, 'HH24:MI') <= '19:29' then
'Morning'
when to_char(sysdate, 'HH24:MI') >= '19:30'
and to_char(sysdate, 'HH24:MI') <= '23:59' then
'Night'
when to_char(sysdate, 'HH24:MI') >= '00:00'
and to_char(sysdate, 'HH24:MI') <= '06:59' then
'Night'
end
and s.badgeid_fk not in
(select empid

end
,'YYYY-MM-DD HH24:MI')
and to_date(case
when to_char(sysdate, 'HH24:MI') >= '07:00'
and to_char(sysdate, 'HH24:MI') <= '19:29' then
to_char(sysdate, 'YYYY-MM-DD') || ' 19:29'
when to_char(sysdate, 'HH24:MI') >= '19:30'
and to_char(sysdate, 'HH24:MI') <= '23:59' then
to_char(sysdate, 'YYYY-MM-DD') || ' 23:59'
when to_char(sysdate, 'HH24:MI') >= '00:00'
and to_char(sysdate, 'HH24:MI') <= '06:59' then
to_char(sysdate, 'YYYY-MM-DD') || ' 06:59'
end
,'YYYY-MM-DD HH24:MI'))))
该查询功能是获得百分比。
如上所示，您可以根据今天的日期和时间范围自动设置日期。
日期时间范围查询：
＆＃39; 07：00＆＃39; - ＆＃39; 19：29＆＃39; OK
＆＃39; 19：30＆＃39; - ＆＃39; 23：59＆＃39;行
现在当我们准时：00.00 - 06.59，我想要查询基于：
＆＃39; 19：30＆＃39; - ＆＃39; 23：59＆＃39;和昨天的日期和
＆＃39; 00：00＆＃39; - ＆＃39; 06：59＆＃39;今天约会。
您可以参考此fiddle
答案 0 :(得分：1)
基于系统日期/时间编写代码的问题是，一旦设置它就会变得多余。我不认为你的sqlfiddle非常有用，因为它返回0％。
另外，你要问的是什么并不清楚。您是否可以使用以下内容来清楚地表达您对下表中显示的每个“s.ysdate”值的期望。请注意，列y，y2，x1，x2是从查询中提取的。
