我想申請在essper此查詢外連接: select a.partA, b.partB, b.count from call.win:time_batch(_WINDOW_) as a
left outer join (select count(*) count, partA from
call.win:time_batch(_WINDOW_) group by partA) b on a.pa
EPL是這樣不起作用: select cast(a.ReportTime,date,dateformat:'yyyy-MM-dd') as ReportTime, a.Source, aa.RequestNum, a.ServerTotal, a.ServerSucc, b.Total, b.Succ, NULL as DataChange_LastTime, c.Response from In
我想知道爲什麼日期格式在一些字段之間是不同的。我的原則聲明如下: @Name("measurement_occupation")
context ParkingSpotOccupation
insert into CreateMeasurement
select
e.source as source,
"ParkingSpotOccupation" as type,
