Question

我已经使用MySql Workbench生成了一个sql脚本。

当我尝试创建我的数据库时，我有“错误1215 1215 - 无法添加外键约束”。

问题似乎与我在上一个创建表中的最后一个外键有关：

CONSTRAINT `fk_tb_animation_option_col_debut`
FOREIGN KEY (`DT_ANO_DEBUT`)
REFERENCES `brest2016`.`tb_animation_option` (`DT_ANO_DEBUT`)
ON DELETE NO ACTION
ON UPDATE NO ACTION)

这是我的整个剧本：

必须为外键中指定的列编制索引。

CREATE TABLE IF NOT EXISTS `brest2016`.`tb_animation_option` (
  `D_AN_CODE` INT(3) NOT NULL,
  `D_OP_CODE` INT(3) NOT NULL,
  `DT_ANO_DEBUT` DATETIME NOT NULL,
  `DT_ANO_FIN` DATETIME NOT NULL,
  `D_ANO_PLACES_MAX` INT(3) NOT NULL,
  `D_ANO_DUREE` INT(3) NOT NULL,
  PRIMARY KEY (`D_AN_CODE`, `D_OP_CODE`, `DT_ANO_DEBUT`),
  INDEX `fk_tb_option_idx` (`D_OP_CODE` ASC),
  INDEX `dt_ano_debut_idx` (`T_ANO_DEBUT`), -- Add this line
  CONSTRAINT `fk_tb_animation_col_code`
    FOREIGN KEY (`D_AN_CODE`)
    REFERENCES `brest2016`.`tb_animation` (`D_AN_CODE`)
    ON DELETE NO ACTION
    ON UPDATE NO ACTION,
  CONSTRAINT `fk_tb_option_col_code`
    FOREIGN KEY (`D_OP_CODE`)
    REFERENCES `brest2016`.`tb_option` (`D_OP_CODE`)
