Answer 1

试试这个：

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正试图向某个字段插入一些值，但您没有为其分配足够的大小来保存该值。你能发送你收到的确切错误信息吗？

我尝试这样做 myself.But 我得到的错误是你插入查询到 Grade table 外键失败引用 Student table 因为你试图插入 Student_IDs 学生 table

Answer 4

我没有收到任何插入课程语句的错误。我收到 INSERT INTO Grade 语句的错误。这是因为 Student table 中没有可用的 StudentID 012,013 等参考。而您正在尝试将它们添加到 table 年级。

mysql 语句不会插入
