Update only the int in MySQL Field
Let us first create a table −
mysql> create table DemoTable702 (
StudentId int NOT NULL AUTO_INCREMENT PRIMARY KEY,
StudentName varchar(100),
StudentScore int
);
Query OK, 0 rows affected (0.56 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable702(StudentName,StudentScore) values('Chris',56);
Query OK, 1 row affected (0.19 sec)
mysql> insert into DemoTable702(StudentName,StudentScore) values('Robert',21);
Query OK, 1 row affected (0.21 sec)
mysql> insert into DemoTable702(StudentName,StudentScore) values('Mike',89);
Query OK, 1 row affected (0.17 sec)
mysql> insert into DemoTable702(StudentName,StudentScore) values('David',99);
Query OK, 1 row affected (0.20 sec)Display all records from the table using select statement −
mysql> select *from DemoTable702;
This will produce the following output -
+-----------+-------------+--------------+
| StudentId | StudentName | StudentScore |
+-----------+-------------+--------------+
| 1 | Chris | 56 |
| 2 | Robert | 21 |
| 3 | Mike | 89 |
| 4 | David | 99 |
+-----------+-------------+--------------+
4 rows in set (0.00 sec)
Here is the query to update int in MySQL −
mysql> update DemoTable702 set StudentScore=StudentScore+9 where StudentId=2;
Query OK, 1 row affected (0.09 sec)
Rows matched: 1 Changed: 1 Warnings: 0
Let us check table records once again −
mysql> select *from DemoTable702;
This will produce the following output -
+-----------+-------------+--------------+
| StudentId | StudentName | StudentScore |
+-----------+-------------+--------------+
| 1 | Chris | 56 |
| 2 | Robert | 30 |
| 3 | Mike | 89 |
| 4 | David | 99 |
+-----------+-------------+--------------+
4 rows in set (0.00 sec)
