             Summary: Support table function calls without parentheses
                 Key: CALCITE-7935
                 URL: https://issues.apache.org/jira/browse/CALCITE-7935
             Project: Calcite
          Issue Type: Improvement

            Assignee: Kirill Tkalenko


Allow invoking parameterless table functions without parentheses after the 
function name:

 

{{SELECT * FROM TABLE(my_func)}}

 

Currently, Calcite requires {{{}TABLE(my_func()){}}}.

Oracle allows omitting parentheses when calling functions without arguments:
