Postgres:整数超出范围

Question

我正在运行以下查询:

WITH match_team_vals(match_id, team_id, is_radiant) AS (
VALUES 
(2281450916, 2783913, true),
(2281450916, 2538753, false)
)

INSERT INTO dota_match_team(match_id, team_id, is_radiant)
SELECT match_id, team_id, is_radiant
FROM match_team_vals
RETURNING id AS lineup_id

在这张桌子上:

CREATE TABLE dota_match_team
(
  id serial NOT NULL,
  match_id integer NOT NULL,
  team_id integer,
  is_radiant boolean NOT NULL,
  CONSTRAINT dota_match_teams_pkey PRIMARY KEY (id)
)

我得到的错误信息是

ERROR: integer out of range
SQL state: 22003

我已经尝试将match_id和team_id强制转换为bigint.同时在线查看我看到人们在串口达到整数上限时遇到了这个问题.似乎并非如此:

SELECT nextval('dota_match_team_id_seq')
returns 31

考虑更改表以使用更大的整数(有关详细信息,请参阅此处:http://www.postgresql.org/docs/9.1/static/datatype-numeric.html).

我认为问题是,你的match_id和team_id有型的integer,你尝试插入值2281450916,但整数的最大值2147483647
