在服务器

中执行SQL脚本

  

错误：错误1215：无法添加外键约束

SQL代码：

CREATE TABLE IF NOT EXISTS `CAREIS101`.`Lecture` (
    `idLecture` INT NOT NULL AUTO_INCREMENT COMMENT '',
    `Lecture_name` VARCHAR(45) NULL COMMENT '',
    `Time` TIME NULL COMMENT '',
    `Date` DATE NULL COMMENT '',
    `Subject` VARCHAR(45) NULL COMMENT '',
    `Block` VARCHAR(45) NULL COMMENT '',
    `Semester` VARCHAR(45) NULL COMMENT '',
    `Room` VARCHAR(45) NULL COMMENT '',
    `Program_idProgram` INT NOT NULL COMMENT '',
    `Program_Stud_Info_Stud_Num` INT NOT NULL COMMENT '',
    `Lecturer_idLecturer` INT NOT NULL COMMENT '',

    PRIMARY KEY (`idLecture`)  COMMENT '',

    INDEX `fk_Lecture_Program1_idx` (`Program_idProgram` ASC, `Program_Stud_Info_Stud_Num` ASC)  COMMENT '',
    INDEX `fk_Lecture_Lecturer1_idx` (`Lecturer_idLecturer` ASC)  COMMENT '',

    UNIQUE INDEX `Program_idProgram_UNIQUE` (`Program_idProgram` ASC)  COMMENT '',
    UNIQUE INDEX `Program_Stud_Info_Stud_Num_UNIQUE` (`Program_Stud_Info_Stud_Num` ASC)  COMMENT '',
    UNIQUE INDEX `Lecturer_idLecturer_UNIQUE` (`Lecturer_idLecturer` ASC)  COMMENT '',

    CONSTRAINT `fk_Lecture_Program1`
        FOREIGN KEY (`Program_idProgram` , `Program_Stud_Info_Stud_Num`)
        REFERENCES `CAREIS101`.`Program` (`idProgram` , `Stud_Info_Stud_Num`)
        ON DELETE NO ACTION
        ON UPDATE NO ACTION,
    CONSTRAINT `fk_Lecture_Lecturer1`
        FOREIGN KEY (`Lecturer_idLecturer`)
        REFERENCES `CAREIS101`.`Lecturer` (`idLecturer`)
        ON DELETE NO ACTION
        ON UPDATE NO ACTION)

    ENGINE = InnoDB

  

SQL脚本执行完成：语句：8成功，1失败

     

以最终形式获取视图定义。   没什么可取的
