Answer 1

SQL 1005与外键问题有关。因此，请检查“RINK”，“OPPONENT”和“division / team”表是否存在指定的主键。

我认为对于Opponent表，你必须指定opponent_id作为外键来代替opponent_name。

请检查

CREATE TABLE IF NOT EXISTS `czhen_hockey_db`.`hockey_db` (
      `id` INT NOT NULL,
      `Date` VARCHAR(45) NOT NULL,

      `division/team_id` INT NOT NULL,
      `opponent_id` INT NOT NULL,
      INDEX `fk_hockey_db_rink_idx` (`rink_id` ASC),
      INDEX `fk_hockey_db_division/team1_idx` (`division/team_id` ASC),
