Insertion in a MySQL table with only a single column set as auto_increment?

Let us first create a table −

mysql> create table DemoTable    -> (    -> StudentId int NOT NULL AUTO_INCREMENT,    -> PRIMARY KEY(StudentId)    -> ); Query OK, 0 rows affected (0.60 sec)

Insert some records in the table using insert command. Here, we have inserted a value, but since it is AUTO_INCREMENT, therefore, the default value would be visible −

mysql> insert into DemoTable(StudentId) values(0); Query OK, 1 row affected (0.18 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable;

This will produce the following output. The default AUTO_INCREMENT value 1 as the first value is visible −

+-----------+ | StudentId | +-----------+ | 1 | +-----------+ 1 row in set (0.00 sec)
