Subject: overwrite column data select - Postgres 9.2
I've got a table with email column:
email CHARACTER VARYING(50) DEFAULT ''::CHARACTER VARYING NOT NULL,
An off-topic question.
Does your application explicitly restrict the length of email addresses
to 50 characters? Are you able to dictate an email address maximum
length of 50 characters? Or do you actually expect your application to
be able accept any valid email address from users?
The reason I ask is -- the maximum length of a valid email address is
actually 256 characters (or 254, according comments in the PHP function
is_valid_email_address(...) that I found on the Internet at
http://code.iamcal.com/ and use myself).
In my own PG DDL, I define email addresses like:
contact_email_addr varchar(256) NOT NULL,
Disclosure: I'm a PG newbie (and a relative SQL newbie, too), and not
familiar with the DEFAULT ":: notation in your DDL.

There are 30k rows and the email column is not null... there is data
in
there.
But for testing purpose I need to overwrite the email. So the customer
won't get an email from me while testing code.
The email could be replaced by: test.UID@xxxxxxxxxxx
How can I do that?
Thanks!
Patrick
