Can you help me please

INSTRUCTION.

PL/SQL

For the exercise below, you must create the Employee/Department database (script provided BELOW ). You must also create a copy of the EMPLOYEES table. In order to create an exact copy of the EMPLOYEEES table, run the following SQL statement. Use your first and last initials in the new table name. For example, if your name is John Smith, then the new table name should be JS_EMPLOYEES. CREATE TABLE AA_employees (AA is my initials, you must use your initials instead of AA) AS SELECT * FROM EMPLOYEES; Create a PL/SQL block that updates the salary of every employee to a new value of 10000 in a chosen department. Include a user-defined exception handler that:

A) handles the condition where no rows are updated and display a custom message

B) will trap any other possible error condition and display the corresponding SQLCODE and SQLERRM.

Test your code three times for the department_ids: 20, 30, and 40
