i just need the second question

1) Write a PL/SQL block that extracts and displays the area code, exchange, and line number from a customer's phone number. Use the skeleton code provided. DECLARE curr_phone VARCHAR2(30) := *(514) 744-7500"; area_code VARCHAR2( 3); gets assigned 514' below exchange -- gets assigned 744' below Tine_num -- gets assigned 7500' below phone_num gets assigned '5147447500 BEGIN area_code :- SUBSTR(curr_phone, ...); exchange :- line_num phone_num --print the phone_num, which has only digits END: Using the given name and salary, complete the PL/SQL, block that calculates a raise using the following formula: If the salary is less than $20k then the raise is $900. If the salary is between $20k and $sok, inclusive, then the raise is 3%. If the salary is above $sok then the raise is 2.75%. On one line of output, give the employee's name, original salary, amount of the raise (in dollars), and the new salary. 2) DECLARE first_name VARCHAR2(30) :- 'Alice' last_name VARCHAR2(30) :-Jones' salary NUMBER(9.2) := 40000; raise new_salary BEGIN dbms_output.put_line(RPAD(first_name, 31) || RPAD.... 31) 11 TO_CHARC ... '59.999,999.99') 11 ...); END
