Hi all,
I tried to run a siddhi query in a java application which works perfectly
in wso2CEP.
Query: (which works in wso2CEP) [1]
from a=obd_speed,b=obd_speedselect b.speed-a.speed as speedDifference,b.time
- a.time as timeInterval, b.time as timeStampinsert into
obd_accele_calculation;
Query in the java application ( Used the sample [2] )
String queryReference = siddhiManager.addQuery("from cseEventStream
a=cseEventStream , b=cseEventStream " +
"select b.price - a.price as priceDiff, symbol insert into
StockQuote ;");
Gives this error [3]
Siddhi version used is 1.0.1 .
Even failed with 2.1 and 2.2 (built from the source)
Is the query in a wrong format?
Any thoughts?
Thank you
