Selecting rows using the ENUM field in MySQL

MySQLMySQLi Database

Let us first create a table −

mysql> create table DemoTable
   -> (
   -> EmployeeStatus ENUM('FULLTIME','Intern') default NULL
   -> );
Query OK, 0 rows affected (0.66 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable values('FULLTIME');
Query OK, 1 row affected (0.19 sec)
mysql> insert into DemoTable values('Intern');
Query OK, 1 row affected (0.10 sec)
mysql> insert into DemoTable values('Intern');
Query OK, 1 row affected (0.10 sec)
mysql> insert into DemoTable values();
Query OK, 1 row affected (0.12 sec)

Display all records from the table using select statement −

mysql> select * from DemoTable;

This will produce the following output −

+----------------+
| EmployeeStatus |
+----------------+
| FULLTIME       |
| Intern         |
| Intern         |
| NULL           |
+----------------+
4 rows in set (0.00 sec)

Here is the query to select rows using the ENUM field in MySQL −

mysql> select * from DemoTable
   -> where EmployeeStatus is null or EmployeeStatus <> 'Intern';

This will produce the following output−

+----------------+
| EmployeeStatus |
+----------------+
| FULLTIME       |
| NULL           |
+----------------+
2 rows in set (0.00 sec)
