First, I want to thank to everybody on such afast respond. Thank you.
Second,
what would be difference between concat_ws and the Randalll's solution
(bellow)?

Could you use something like this (untried):
SELECT
CONCAT(COALESCE(r.first_name, ''), ' ',
COALESCE(r.last_name, ''), '\n',
COALESCE(r.organization, ''), '\n',
COALESCE(r.title, ''), '\n',
COALESCE(a.address1, ''), '\n',
COALESCE(a.city, ''), ', ',
COALESCE(a.state, ''), ' ',
COALESCE(a.zip, ''), '\n',
COALESCE(r.email, ''))
FROM
registrants r,
addresses a
WHERE
r.reg_id=121

Subject: CONCAT doesn't work with NULL?
hi,
I have query
SELECT CONCAT(r.first_name, ' ', r.last_name, '\n', r.organization,
'\n', r.title, '\n', a.address1, '\n', a.city, ', ', a.state, ' ',
a.zip, '\n', r.email)
FROM registrants r, addresses a
WHERE r.reg_id=121
if any of columns has value (e.g. title) NULL, I'll get as result 0
records.
If query doesn't have concat() - it works fine.
Why is that?
