[GENERAL] Recurring bookings

[Kevin Waterson]

So far this is what I have.. (see below).
How can I have recurring bookings for a call?
Eg: if the call_frequency is weekly, how can I see a list of dates which
this account will be called upon?

Kind regards
Kevin


CREATE TABLE call_frequency (
        id SERIAL PRIMARY KEY NOT NULL,
        name varchar(25) NOT NULL,
        description VARCHAR(200) NOT NULL
);
COMMENT ON TABLE call_frequency IS 'How often a call is scheduled';
INSERT INTO call_frequency( name, description ) VALUES ('Once Only',
'Single non-recurring call' );
INSERT INTO call_frequency( name, description ) VALUES ('Hourly', 'Every
hour' );
INSERT INTO call_frequency( name, description ) VALUES ('Daily', 'Every
day' );
INSERT INTO call_frequency( name, description ) VALUES ('Weekly', 'Every
week' );
INSERT INTO call_frequency( name, description ) VALUES ('Bi-Weekly', 'Every
second week' );
INSERT INTO call_frequency( name, description ) VALUES ('Monthly', 'Every
Month' );
INSERT INTO call_frequency( name, description ) VALUES ('Yearly', 'Every
Year' );


CREATE TABLE callcard (
        id SERIAL PRIMARY KEY NOT NULL,
        account_id INT NOT NULL REFERENCES accounts(id),
        user_id INT NOT NULL REFERENCES users(id),
        call_type_id INT NOT NULL REFERENCES call_types(id),
        call_frequency_id INT NOT NULL REFERENCES call_frequency(id),
        duration TSRANGE NOT NULL
