如何用日期列创建表？
要创建仅包含日期列的表，可以使用DATE类型。让我们首先创建一个表-
mysql> create table DemoTable ( StudentId int NOT NULL AUTO_INCREMENT PRIMARY KEY, StudentName varchar(20), StudentAdmissionDate DATE );
使用插入命令在表中插入记录-
mysql> insert into DemoTable(StudentName,StudentAdmissionDate) values('Chris',now());
mysql> insert into DemoTable(StudentName,StudentAdmissionDate) values('Robert',curdate());
mysql> insert into DemoTable(StudentName,StudentAdmissionDate) values('David','2019-05-21');使用select语句显示表中的所有记录-
mysql> select * from DemoTable;
这将产生以下输出-
+-----------+-------------+----------------------+ | StudentId | StudentName | StudentAdmissionDate | +-----------+-------------+----------------------+ | 1 | Chris | 2019-04-27 | | 2 | Robert | 2019-04-27 | | 3 | David | 2019-05-21 | +-----------+-------------+----------------------+ 3 rows in set (0.00 sec)
