Set AUTO_INCREMENT in a table while creating it in MySQL?
Let us first create a table. We have used AUTO_INCREMENT while creating the table to set auto increment for StudentId −
mysql> create table DemoTable
-> (
-> StudentId int NOT NULL AUTO_INCREMENT,
-> StudentFirstName varchar(100),
-> StudentLastName varchar(100),
-> StudentAge int,
-> StudentCountryName varchar(100),
-> PRIMARY KEY(StudentId)
-> )AUTO_INCREMENT=30;
Query OK, 0 rows affected (0.69 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable(StudentFirstName,StudentLastName,StudentAge,StudentCountryName) values('John','Smith',21,'US');
Query OK, 1 row affected (0.17 sec)
mysql> insert into DemoTable(StudentFirstName,StudentLastName,StudentAge,StudentCountryName) values('Chris','Brown',20,'AUS');
Query OK, 1 row affected (0.19 sec)Display all records from the table using select statement −
mysql> select *from DemoTable;
Output
+-----------+------------------+-----------------+------------+--------------------+
| StudentId | StudentFirstName | StudentLastName | StudentAge | StudentCountryName |
+-----------+------------------+-----------------+------------+--------------------+
| 30 | John | Smith | 21 | US |
| 31 | Chris | Brown | 20 | AUS |
+-----------+------------------+-----------------+------------+--------------------+
