Guy Rouillier,
thank you.
I have emails in CHARACTER(60) type columns in database, total 3000 emails.
I need to check email addresses for most frequent typos before send.
I have only plpgsql language installed, no perl.
From this thread I got the regular expression
/^[^@]*@(?:[^@]*\.)?[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)$/How
Ican use this in where clause ? I havent never used regular expressionsin Postgres.How to exclude top-level domain
namesfrom this regex ?Andrus.
