Can we insert records in a MySQL table without auto_increment values?
Yes, we can insert without the auto_increment since it gets inserted on its own. Let us first create a table −
mysql> create table DemoTable1479 -> ( -> EmployeeId int NOT NULL AUTO_INCREMENT PRIMARY KEY, -> EmployeeSalary int -> ); Query OK, 0 rows affected (0.86 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable1479(EmployeeSalary) values(6800); Query OK, 1 row affected (0.10 sec) mysql> insert into DemoTable1479(EmployeeSalary) values(5600); Query OK, 1 row affected (0.11 sec) mysql> insert into DemoTable1479(EmployeeSalary) values(5700); Query OK, 1 row affected (0.16 sec) mysql> insert into DemoTable1479(EmployeeSalary) values(6900); Query OK, 1 row affected (0.14 sec) mysql> insert into DemoTable1479(EmployeeSalary) values(15000); Query OK, 1 row affected (0.11 sec)
Display all records from the table using select statement −
mysql> select * from DemoTable1479;
This will produce the following output −
+------------+----------------+ | EmployeeId | EmployeeSalary | +------------+----------------+ | 1 | 6800 | | 2 | 5600 | | 3 | 5700 | | 4 | 6900 | | 5 | 15000 | +------------+----------------+ 5 rows in set (0.00 sec)
