----------------------------------

             Summary: Allow 'expressions' instead of 'constant literal' for 
EXECUTE
                 Key: HIVE-24002
                 URL: https://issues.apache.org/jira/browse/HIVE-24002
             Project: Hive
          Issue Type: Sub-task
          Components: Query Planning
            Reporter: Vineet Garg
            Assignee: Vineet Garg


Currently EXECUTE statement grammar allows constant literal only. This prevents 
negative literals or constant expressions like {{1+2}}. Changing it to 
{{expression}} type will allow broader type of literals. Note that this will 
require additional error checking after parsing to only allow "acceptable" 
literals.
