How do I replace field content in PL/SQL?

In PL/SQL, you can use the UPDATE statement to replace the content of a field. Here is a simple example:

Suppose there is a table named “employees” that contains the following fields:

  1. worker identification number
  2. worker’s name
  3. wages

To replace the salary of a specific employee, you can use the following UPDATE statement:

UPDATE employees
SET salary = 5000
WHERE employee_id = 100;

The statement above updates the salary of the employee with the “employee_id” of 100 to 5000. You can modify the UPDATE statement according to your specific requirements to replace the content of different fields.
