[jira] [Created] (EMPIREDB-253) Add UNION ALL support to DBCommand

Ivan Nemeth created EMPIREDB-253:
------------------------------------

             Summary: Add UNION ALL support to DBCommand
                 Key: EMPIREDB-253
                 URL: https://issues.apache.org/jira/browse/EMPIREDB-253
             Project: Empire-DB
          Issue Type: Improvement
          Components: Core
            Reporter: Ivan Nemeth
            Priority: Minor


Currently only UNION is implemented, UNION ALL can be implemented with the same pattern.

public DBCommandExpr unionAll(DBCommandExpr other)
    {   // give driver a chance to subclass DBCombinedCmd
    	DBDatabaseDriver driver = getDatabase().getDriver();
    	return driver.createCombinedCommand(this, "UNION ALL", other);
    }
