How to trigger the error messages in ODBCMessages.xml and VerticaMessages.xml

On Linux, you can test with "isql" client in verbose mode:
$ isql -v vertica
SQL> select count(distinct x), listagg(y) from myTable;
[42703]ERROR 2624: Column "x" does not exist

Thanks for your reply.
Yes, I will get the same error, but this error template could not be found in ODBCMessages.xml or VerticaMessages.xml.
Instead, I can find one similar error in ODBCMessages.xml
<!-- Error thrown when a specified column name is invalid or not found. -->
<Error Key="InvalidColumnName" Params="1" NativeErrorCode="20021">Invalid column name: %1%</Error>

Could you please help to provide more information on how to make error messages in these two xml files take effort?
