    using a full outer join in an Oracle cql query

    997545
      Hi everybody!
      I am currently using Oracle CEP and I want to use a Full out join in order to aggregate somme streams. Is there any way to do that? It seems that you can either use a right or a left join.
      Thanks a lot for your help!

          Hello,

          You can refer to the CQL guide: http://docs.oracle.com/cd/E23943_01/apirefs.1111/e12048/queries.htm#CIHEFDGI, where it also describe the inner/outer join.
          There is a sample provide call cql provided with the installation where you can test CQL using CEP Visualizer : reference can be found
          http://docs.oracle.com/cd/E23943_01/doc.1111/e14476/examples.htm#CIHIJHHJ

          An easy way to play around with CQL is to build a simple CEP flow : CSV adapter->channelIN->CQL processor->channelOUT-> Listener (define also the needed event type).
          Then use the CEP Visualizer to test or create (through wizzard) your CQL statement.
