Hi,
I am using sample flow like this.
MQInput ---> ComputeNode-->MQOuptput
I am using the Destination list for sending the message to the multiple Queues.
My concern is if i want to add a new queue name every time i have to change the code.....is it possible to include the other queue name , without modifying the ESQL code ? like using the UDP params. |

Without testing
IF udp_attr1 IS NOT NULL THEN
SET OutputLocalEnvironment.Destination.MQ.DestinationData[i++].queueName= udp_attr1;
END IF;
IF udp_attr2 IS NOT NULL THEN
SET OutputLocalEnvironment.Destination.MQ.DestinationData[i++].queueName= udp_attr2;
END IF;
IF udp_attr3 IS NOT NULL THEN
SET OutputLocalEnvironment.Destination.MQ.DestinationData[i++].queueName= udp_attr3;
END IF;
IF …
Where :
udp_attrX = udp parameters.

one lil dirty logic is ..
have one UDP for destination list
separate all the destinations by some delimiter say ;
build env tree
and create destination list

as i mentioned earlier..
separate all the destinations by some delimiter say ; or ,
accept this in eSQL and extract each destination from the UDP
create destination list from the extracted destinations
