RE: Returned row count doesn't match lines in output file

Thank you so much for responding.

Yes, one of the selected columns is null; when I only select one column tha=
t I know can't be a null, it returns all of them.  I changed it to the belo=
w and it worked just fine, thank you so much.

select u.user_id||'|'||coalesce(u.firstname,'')||'|'||coalesce(u.lastname,'=
')||'|'||coalesce(u.email,'')||'|'||coalesce(u.student_id,'')

Null values in one or more of the columns you're concatenating, perhaps?
Concatenating a null with something else yields null.  (See
coalesce() for one ad-hoc way to fix that.)
