DELETE from MySQL table WHERE column equals value AND column2 equals value2?

MySQLMySQLi Database

Let us first create a table −

mysql> create table DemoTable722 (
   StudentId int NOT NULL AUTO_INCREMENT PRIMARY KEY,
   StudentName varchar(100),
   StudentAge int
);
Query OK, 0 rows affected (1.84 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable722(StudentName,StudentAge) values('Chris Brown',23) ;
Query OK, 1 row affected (0.24 sec)
mysql> insert into DemoTable722(StudentName,StudentAge) values('John Smith',21);
Query OK, 1 row affected (0.18 sec)
mysql> insert into DemoTable722(StudentName,StudentAge) values('David Miller',22);
Query OK, 1 row affected (0.17 sec)
mysql> insert into DemoTable722(StudentName,StudentAge) values('Adam Smith',20);
Query OK, 1 row affected (0.24 sec)
mysql> insert into DemoTable722(StudentName,StudentAge) values('Carol Taylor',24);
Query OK, 1 row affected (0.39 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable722;

This will produce the following output -

+-----------+--------------+------------+
| StudentId | StudentName  | StudentAge |
+-----------+--------------+------------+
| 1         | Chris Brown  | 23         |
| 2         | John Smith   | 21         |
| 3         | David Miller | 22         |
| 4         | Adam Smith   | 20         |
| 5         | Carol Taylor | 24         |
+-----------+--------------+------------+
5 rows in set (0.00 sec)

Following is the query to delete from MySQL table WHERE column equals value AND column2 equals value2 −

mysql> delete from DemoTable722 where StudentId=3 and StudentName='David Miller';
Query OK, 1 row affected (0.21 sec)

Let us check table records once again −

mysql> select *from DemoTable722;

This will produce the following output -

+-----------+--------------+------------+
| StudentId | StudentName  | StudentAge |
+-----------+--------------+------------+
| 1         | Chris Brown  | 23         |
| 2         | John Smith   | 21         |
| 4         | Adam Smith   | 20         |
| 5         | Carol Taylor | 24         |
+-----------+--------------+------------+
4 rows in set (0.00 sec)
