Mysql SQL中的外键引用不起作用

我试图创造一组球员和球队。每个队员都属于一个队。我在teams表中将“team”属性引用为“teamID”。但我不断得到错误：请检查父表团队的表播放器上的外键约束

CREATE TABLE players (
  playerid    INTEGER PRIMARY KEY, 
  name  text,
  position text,
  skill text,
  team integer,
  FOREIGN KEY(team) REFERENCES teams(teamID)

);

CREATE TABLE teams (
  teamID     INTEGER primary key, 
  name   text unique, 
  city text,
  coach text
  /*captain text*/

);

INSERT INTO players VALUES (1, "Tom Chapin", "Quorter Back", "Advanced SKill", 1);
INSERT INTO players VALUES (2, "Harry Chapin", "LineBacker", "Begginer", 2);

/* Tom's songs */
INSERT INTO teams VALUES (1, "Chicago Bears", "Chicago", "Coach Jack");
INSERT INTO teams VALUES (2, "Detroit Bulls", "Detroit", "Coach Bob");
/* Harry's songs */
INSERT INTO teams VALUES (3, "NY Snakes", "New York", "Coach Phil");


SELECT * from players;
SELECT * FROM teams;

需要先存在引用表中的行，然后才能插入行

您正在尝试将行插入播放机。但这些都是参考团队

---

您需要先插入球队记录。

请在创建table player之前创建table team

CREATE TABLE teams (
  teamID     INTEGER primary key, 
  name   varchar(255) unique, 
  city text,
  coach text
)

CREATE TABLE players (
  playerid    INTEGER PRIMARY KEY, 
  name  varchar(255),
  position text,
  skill text,
  team integer,
  FOREIGN KEY(team) REFERENCES teams(teamID)

);


/* Tom's songs */
INSERT INTO teams VALUES (1, "Chicago Bears", "Chicago", "Coach Jack");
INSERT INTO teams VALUES (2, "Detroit Bulls", "Detroit", "Coach Bob");
/* Harry's songs */
INSERT INTO teams VALUES (3, "NY Snakes", "New York", "Coach Phil");

INSERT INTO players VALUES (1, "Tom Chapin", "Quorter Back", "Advanced SKill", 1);
INSERT INTO players VALUES (2, "Harry Chapin", "LineBacker", "Begginer", 2);

Mysql还是postgresql？
