How to modify data in a specific column in Oracle?

To update the data in a column of an Oracle database table, you can use the UPDATE statement. Here is an example:

Suppose there is a table called “employees” with columns “employee_id” and “salary”. Now we need to increase the salary by 10% for all employees in the “salary” column with values greater than 5000.

UPDATE employees
SET salary = salary * 1.1
WHERE salary > 5000;

By using the above UPDATE statement, the salary of all employees in the “employees” table with a salary greater than 5000 can be increased by 10%.

Please remember to backup your data before executing the UPDATE statement to prevent any unexpected situations.
