Provided that WorkPhone is blank, the query above make sense to me.
The output would be "2323223,,323232232,test@test.com". But if the
double comma wasn't there, how would you know which number that is
missing?

If WorkPhone is NULL, the entire expression will be NULL. In this
case you must use coalesce(WorkPhone, '') and similar for the other
columns.
