How to read an incoming message from a MQ as columns?
The message from MQ is predefined (when writing to a queue) into some columns (Ex: EmpID , Name , Address). When reading messages into the application a requirement arises to read the incoming message as the defined columns.
Is there any direct API support to do this? Or any smart way to handle this? |

You should write some split function, which will populate data into EmpId, Name, Address, etc. fields using the BUFFER returned by your MQGET call.

It depends on the programming language you are using.
If you are working with something like C or Cobol or most procedural languages, you will generally map a pre-defined structure on the buffer pointer received from MQGET.
If you are working with Java, you will call methods methods of the MQMessage to retrieve requested data types (readInt, readString...).
