Обсуждение: CONSTRAINT on ARRAY ELEMENTS
CREATE TABLE employ_presence
(
p_id character(6) not null,
p_month character(3) NOT NULL,
statuscode integer array[7],
CONSTRAINT unq_employ_presence UNIQUE (p_id, p_month),
CONSTRAINT chk_employ_month CHECK (p_month = ANY (ARRAY['Jan'::bpchar, 'Feb'::bpchar, 'Mar'::bpchar, 'Apr'::bpchar, 'May'::bpchar, 'Jun'::bpchar, 'Jul'::bpchar, 'Aug'::bpchar, 'Sep'::bpchar, 'Oct'::bpchar, 'Nov'::bpchar, 'Dec'::bpchar]))
);
How can add a CONSTRAINT on statuscode array elements to accept values between 0 to 5
0 = Employ present
1 = Employ Patient
2 = day off
3 = Regular vacation
4 = external job assignment
5 = external job assignment abroad
6 to 9 for future use
Thanks.
Hey Nikolaos,
I recommend you to create the table "status" and create
foreign key constraint in the table "employ_presence"
instead. This will do exactly what are you want.

You can try:
CHECK (statuscode <@ ARRAY[1,2,3,4,5])
