Postgres:整数超出范围 [英] Postgres: integer out of range

问题描述

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

我尝试将 match_id 和 team_id 转换为 bigint.也在网上看我看到人们有这个问题，串行达到整数的上限.似乎并非如此:

I've tried casting the match_id and team_id to bigint. Also looking online I see that people have this issue with the serial hitting the upper limit of integers. This doesn't seem to be the case:

SELECT nextval('dota_match_team_id_seq')
returns 31

推荐答案

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

Consider altering your table to use a bigger integer (see here for details: http://www.postgresql.org/docs/9.1/static/datatype-numeric.html).

我认为问题在于，您的 match_id 和 team_id 属于 integer 类型，而您尝试插入值 2281450916，但整数的最大值为 2147483647

I think the problem is, that your match_id and team_id are of type integer and you try to insert the value 2281450916, but integer's maximum is 2147483647
