Hello,
I'm having this table filled with data:
\d pref_users;
Table "public.pref_users"
Column | Type | Modifiers
------------+-----------------------------+---------------
id | character varying(32) | not null
first_name | character varying(32) |
last_name | character varying(32) |
female | boolean |
avatar | character varying(128) |
city | character varying(32) |
lat | real |
lng | real |
last_login | timestamp without time zone | default now()
last_ip | inet |
medals | smallint |
Indexes:
"pref_users_pkey" PRIMARY KEY, btree (id)
Check constraints:
"pref_users_lat_check" CHECK ((-90)::double precision <= lat AND
lat <= 90::double precision)
"pref_users_lng_check" CHECK ((-90)::double precision <= lng AND
lng <= 90::double precision)
"pref_users_medals_check" CHECK (medals > 0)
Referenced by:
TABLE "pref_luck" CONSTRAINT "pref_luck_id_fkey" FOREIGN KEY (id)
REFERENCES pref_users(id)
TABLE "pref_misere" CONSTRAINT "pref_misere_id_fkey" FOREIGN KEY
(id) REFERENCES pref_users(id)
TABLE "pref_money" CONSTRAINT "pref_money_id_fkey" FOREIGN KEY
(id) REFERENCES pref_users(id)
TABLE "pref_pass" CONSTRAINT "pref_pass_id_fkey" FOREIGN KEY (id)
REFERENCES pref_users(id)
TABLE "pref_rate" CONSTRAINT "pref_rate_obj_fkey" FOREIGN KEY
(obj) REFERENCES pref_users(id)
TABLE "pref_rate" CONSTRAINT "pref_rate_subj_fkey" FOREIGN KEY
(subj) REFERENCES pref_users(id)
And then I realized that I actually want
medals smallint default 0 check (medals >= 0)
So I've dropped the old constraint with
alter table pref_users drop constraint "pref_users_medals_check";
but how can I add the new contraint please? I'm trying:
alter table pref_users add constraint pref_users_medals_check (medals >= 0);
ERROR: syntax error at or near "("
LINE 1: ...pref_users add constraint pref_users_medals_check (medals >=...
^
and many combinations of quotes and "check" inbetween,
but can't find the correct syntax
Regards
Alex
