Thanks for the tip. I'm still facing an issue where I think I have the right syntax
and I'm receiving an ODBC failure. Do you have any suggestions on how to go about
understanding why the failure and hence how to correct it?

Keep in mind EXISTS/NOT EXISTS are for SQL (Parent) Heavy queries
Otherwise you should use IN/NOT IN
