4. Conditional update. For example, the following update conditions are available:For employees with a salary of more than 5000, the salary is reduced by 10%.Employees with salaries between 2000 and 4600 increase by 15%You can easily choose to execute two update statements, as shown below: -- Condition 1Update personnelSet salary = salary * 0.9Where salary >=5000;-- Condition 2Update personnelSet salary = salary * 1.15Where salary> = 2000 and salary However, it is not as simple as you think.
