Messages received by a message flow compute node may have MQMD.expiry set to a specific expiration time by the sending application (or a previous compute node as GMTTIMESTAMP), or they may default to unlimited (-1) when received by the queue manager.

How can I check to see what the current expiry value is using esql? If I reference expiry as an Integer variable, I get a 'wrong type exception' when it is set to expire. If I use expiry like a non-integer data type, I get a similar error when expiry is set to -1, unlimited.

Is there a way to check the data type of expiry before assigning its value to a local variable?

Try this:
Code:
SET ExpInterval   = CASE
   WHEN CAST(InputRoot.MQMD.Expiry AS CHARACTER ) = '-1'  THEN -1
   ELSE CAST(((InputRoot.MQMD.Expiry - InputRoot.Properties.CreationTime) SECOND * 10) AS INTEGER)
   END;
