> In current implementation, appendDBName will return null if more than one tables share the table name. The caller is not aware of this, and will put null values into project/cube instance, this will cause runtime errors.

>             return result;
>         if (count > 1) {
>             errorMsgs.add("There are more than 1 table named with '" + table + "' in different database; The program couldn't determine, randomly pick '" + result + "'");
