Steve,
thank you again.
I applied Michael hint about dollar quoting to this and tried
create temp table customer ( email char(60));
insert into customer values( '[EMAIL PROTECTED]');
SELECT email FROM customer WHERE email !~*
$$
[EMAIL PROTECTED]@(?:[EMAIL
PROTECTED])?[a-z0-9_-]+\.(?:a[defgilmnoqrstuwz]|b[abdefghijmnorstvwyz]|c[acdfghiklmnoruvxyz]|d[ejkmoz]|e[ceghrst]|f[ijkmorx]|g[abdefhilmnpqrstuwy]|h[kmnrtu]|i[delnoqrst]|j[mop]|k[eghimnprwyz]|l[abcikrstuvy]|m[acdghklmnopqrstuvwxyz]|n[acefgilopruz]|om|p[aefghklmnrtwy]|qa|r[eouw]|s[abcdeghijklmnortvyz]|t[cdfghjkmnoprtvwz]|u[agkmsyz]|v[aceginu]|w[fs]|y[etu]|z[amw]|edu|com|net|org|gov|mil|info|biz|coop|museum|aero|name|pro|mobi|arpa)$

but this classifies e-mail address [EMAIL PROTECTED] as invalid (select
returns it). The same result are without dollar quoting, using your original
select.
