Read an entry from a queue

The MQRead() function reads a message from the queue but does not remove it.

After reading the message, the queue has not been changed: 
BEGIN WORK;

EXECUTE FUNCTION MQRead('IDS.DEFAULT.SERVICE', 'IDS.DEFAULT.POLICY');

(expression) hello queue

1 row(s) retrieved.

COMMIT WORK;
The following example reads a message from the queue and inserts it into a database table: 
INSERT into msgtable values (MQRead('IDS.DEFAULT.SERVICE', 'IDS.DEFAULT.POLICY'));

1 row(s) inserted.

SELECT * from msgtable;

msg hello queue

1 row(s) retrieved.

COMMIT WORK;
