    I need the following:

    1. we have to create a funcion in which if in the table IPALLILOS the salary of an employee is less than 500 add 200 more.

    2. Increase by 50 bonus for employees who have salary <= 1400 but the last year brought profit> = 1000 (using functions)

    3. Bonus reduction at 150 for employees who the last 4 years brought profit of less than 3000 per year (using functions)

    4. During data entry on the list on the table APODOSI_ETOS for each employee make sure to refresh the table paragwgikothta_ipallilou automatically using trigger (trigger based).

    thanks in advance for the help.

    Sounds like homework. How far have you got and where are you stuck?
