Rainer Döbele created EMPIREDB-145:
--------------------------------------

             Summary: Allow create of DBQuery from DBCommandExpr
                 Key: EMPIREDB-145
                 URL: https://issues.apache.org/jira/browse/EMPIREDB-145
             Project: Empire-DB
          Issue Type: Improvement
          Components: Core
            Reporter: Rainer Döbele
            Assignee: Rainer Döbele


Currently creating a DBQuery object (used for subqueries) requires a DBCommand source object.
However UNIONS and INSTERSECT statements are of type DBCommandExpr - a superclass of DBCommand.
Extend DBQuery to allow DBCommandExpr  as well
