PostgreSQL – Email Regex

· Tech

If you need a simple email address validation for PostgreSQL, here’s a straightforward solution.

CREATE TABLE users
(
    -- ...
    email    VARCHAR(255)    NOT NULL UNIQUE CHECK (email ~* '^\S+@\S+\.\S+$'),
    -- ...
);

You can verify this by running the following SQL query:

SELECT '[email protected]' ~* '^\S+@\S+\.\S+$' AS is_valid;
