Обсуждение: Enum in PostgreSQL - How to

Hello!

Could somebody tell me how i would simulate an ENUM columntype (as in
MySQL). For example:

accountType ENUM('default', 'custom') default='default'

How can i do this in PostgreSQL ?

Thanks a lot in advance for your time and effort.

Best regards,
Jürgen

I tried to answer you on IRC, but you disappeared too quickly.

I looked on google, and found this:

Please CC all posts to the mailing list.

Explaining what "doesn't work" helps, but I think I see the problem.
The example shown in the URL provided is incomplete.  But looking up
that CHECK option will show the correct syntax.  Please see
http://www.postgresql.org/docs/view.php?version=7.3&idoc=0&file=sql-
createtable.html and look in the Examples section:

 name   VARCHAR(40) NOT NULL CHECK (name <> '')

You need a variable time, in your case, I suggest TEXT.

accountType varchar(10) CHECK (accountType='default' or
accountType='custom) DEFAULT 'default'
