我的 SQL 表达式运行良好,可以显示几个月的结果,今年可以。但一年后我知道它将包括今年的结果。如何仅显示当年的结果?
select case month(timestamp_iso(STATUSDATE))
when 1 then 'January'
when 2 then 'February'
when 3 then 'March'
when 4 then 'April'
when 5 then 'May'
when 6 then 'Jun'
when 7 then 'July'
when 8 then 'August'
when 9 then 'September'
when 10 then 'October'
when 11 then 'November'
when 12 then 'December'
end as Month,
count (case when service='ADSL' then 1 end) as ADSL,
count (*) as ALL
from INCIDENT
group by month(timestamp_iso(STATUSDATE))
谢谢
