Answer 1

尝试使用：

INSERT INTO table1 (column1,column2,column3,...)
VALUES (value1,value2,value3,...);

Answer 2

这些是字段类型：

CREATE TABLE Course
(
CourseID int,
Description varchar(20) NOT NULL,
StartDate DATE NOT NULL,
EndDate DATE NOT NULL,
CONSTRAINT [PK_CourseID] PRIMARY KEY (CourseID)
);  

CREATE TABLE Grade
(
GradeID integer(10) NOT NULL,
CourseID integer(10) NOT NULL,
StudentID integer(10) NOT NULL,
Grade varchar (10) NULL,
CONSTRAINT [PK_GradeID] PRIMARY KEY (GradeID),
CONSTRAINT [FK_CourseID] FOREIGN KEY (CourseID) REFERENCES Course(CourseID),
CONSTRAINT [FK_StudentID] FOREIGN KEY (StudentID) REFERENCES Student(StudentID)
);

CREATE TABLE Student
(
StudentID integer(10) NOT NULL,
FirstName varchar(45) NOT NULL,
LastName varchar(45) NOT NULL,
RegistrationDate varchar (45) NOT NULL,
GraduationDate DATE NULL,
CONSTRAINT [PK_StudentlID] PRIMARY KEY (StudentID)
);

Answer 3

字符串或二进制数据将被截断您收到此消息的原因应该是您尝试向某些字段插入一些值，而这些字段尚未分配足够的大小来保存该值。你能发送你得到的确切错误信息吗？

我试图自己做。但是我得到的错误是你从插入查询到Grade表外键失败，它引用了Student表，因为你试图插入不存在于你学生表中的Student_ID

Answer 4

我没有在插入课程语句时遇到任何错误。 INSERT INTO Grade语句出错了。这是因为Student表中没有可用于StudentID 012,013等的参考。而你正试图在等级表中添加它们。

mysql语句不会插入
