Howdy, Tarlika.
If the data doesn't bring the AM/PM how are you supposed to distinguish
between,say, 10pm and 10am ? Does it always start at 10:30am? So 10am never
arises?
Best,
Oliveiros

I am importing data in CSV format. My technique is to COPY the data
into interim tables (starting with a "z") where I analyze them, clean
up inconsistencies; eventually I will populate the "proper" tables with
these data. (In the example below: COPY CSV into zevent, from there
populate event.)
The time field of the event data is givng me a headache: it's in 12h
format but without the AM/PM qualifier!
CREATE TABLE zevent
(
id integer,
previous integer,
"next" integer,
location_id integer NOT NULL,
datum date NOT NULL,
otime character varying(5) NOT NULL
)
CREATE TABLE event
(
id integer NOT NULL,
location_fk integer NOT NULL,
otime timestamp without time zone NOT NULL,
next_fk integer,
previous_fk integer,
CONSTRAINT event_pkey PRIMARY KEY (id),
CONSTRAINT next_event_fk FOREIGN KEY (next_fk)
REFERENCES event (id) MATCH SIMPLE
ON UPDATE NO ACTION ON DELETE NO ACTION,
CONSTRAINT previous_event_fk FOREIGN KEY (previous_fk)
REFERENCES event (id) MATCH SIMPLE
ON UPDATE NO ACTION ON DELETE NO ACTION
)
