Oracle按不同时间分组统计

select to_char(record_date,'yyyy'), sum(col_8) as total_money
from table_name
where group by to_char(record_date,'yyyy')

select to_char(record_date,'yyyy-mm'), sum(col_8) as total_money
from table_name
where group by to_char(record_date,'yyyy-mm')

select to_char(record_date,'yyyy-Q'), sum(col_8) as total_money
from table_name
where group by to_char(record_date,'yyyy-Q')

from table_name
where group by to_char(record_date,'yyyy-IW')

select to_char(record_date,'yyyy-mm-dd hh24'), sum(col_8) as total_money

SELECT trunc(sysdate) + (ROWNUM - 1) / 24/12 AS STAT_TIME

CONNECT BY ROWNUM <=(trunc(sysdate, 'MI') - (trunc(sysdate))) * 24 * 12

按5分钟统计，中间没数据的时间会缺少

create or replace function trunc_minute(v_date date) return date as
