Question

“考试”表格中出现错误，因为日期变量日期 - 我几乎在所有地方（使用谷歌）搜索了答案。

Drop table if exists exams;
CREATE TABLE administration2.exams (
date DATE,
censor VARCHAR(45) ,
idstudents VARCHAR(11),
idcourses VARCHAR(11),
grade INT (11),
PRIMARY KEY (date,censor));

insert into exams(date, censor, idstudents, idcourses, grade)
('2013-11-06', 'Ole Pedersen','201210066', 'dDB', 7),

这是问题（'2013-11-06'） - 它说：

`syntax_error，UNEXPECTED TEXT_STRING，期待SELECT_SYM。

我该如何解决这个问题？

Answer 1

您错过了values声明：

insert into exams(date, censor, idstudents, idcourses, grade)
    values ('2013-11-06', 'Ole Pedersen','201210066', 'dDB', 7);

如果删除括号，也可以使用select执行此操作：

insert into exams(date, censor, idstudents, idcourses, grade)
    select '2013-11-06', 'Ole Pedersen','201210066', 'dDB', 7;

Answer 2

简单和小

insert into exams
    select '2013-11-06', 'Ole Pedersen','201210066', 'dDB', 7 from exams

OR

insert into exams
    values ('2013-11-06', 'Ole Pedersen','201210066', 'dDB', 7);

date日期变量
