How to select all the records except a row with certain id from a MySQL table?

To avoid displaying a certain id from a table, you need to use the operator, which is the NOT EQUAL operator. Let us first create a table −

mysql> create table DemoTable7
(
   StudentId int NOT NULL AUTO_INCREMENT PRIMARY KEY,
   StudentName varchar(40)
);
Query OK, 0 rows affected (0.53 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable7(StudentName) values('Chris');
Query OK, 1 row affected (0.25 sec)
mysql> insert into DemoTable7(StudentName) values('Robert');
Query OK, 1 row affected (0.11 sec)
mysql> insert into DemoTable7(StudentName) values('Mike');
Query OK, 1 row affected (0.12 sec)
mysql> insert into DemoTable7(StudentName) values('Sam');
Query OK, 1 row affected (0.61 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable7;

This will produce the following output −

+-----------+-------------+
| StudentId | StudentName |
+-----------+-------------+
|         1 | Chris       |
|         2 | Robert      |
|         3 | Mike        |
|         4 | Sam         |
+-----------+-------------+
4 rows in set (0.00 sec)

Following is the query to select all the records except a certain ID using the NOT EQUAL operator −

mysql> select *from DemoTable7 where StudentId <> 2;

This will produce the following output −

+-----------+-------------+
| StudentId | StudentName |
+-----------+-------------+
|         1 | Chris       |
|         3 | Mike        |
|         4 | Sam         |
+-----------+-------------+
3 rows in set (0.06 sec)
