View Exhibit 1 and examine the structure of the employees table :
desc employees
Name Null Type
-------------------------------------------------
EMPLOYEE_ID NOT NULL NUMBER(6)
FIRST_NAME VARCHAR2(20)
LAST_NAME NOT NULL CHAR(25)
EMAIL NOT NULL VARCHAR2(25)
PHONE_NUMBER VARCHAR2(20)
HIRE_DATE NOT NULL DATE
JOB_ID NOT NULL VARCHAR2(10)
SALARY NUMBER(8,2)
COMMISSION_PCT NUMBER(2,2)
MANAGER_ID NUMBER(6)
DEPARTMENT_ID NUMBER(4)
View Exhibit 2 and examine the code:
CREATE OR REPLACE FUNCTION increase
(emp_num NUMBER) RETURN NUMBER
IS
inc_amt NUMBER;
sal NUMBER;
BEGIN
SELECT salary INTO sal FROM employees WHERE employee_id = emp_num;
inc_amt := sal*10;
RETURN inc_amt;
END increase;
/
CREATE OR REPLACE PROCEDURE calc_sal IS
emp_num NUMBER(7) := 120;
amt NUMBER :=0;
PROCEDURE raise_salary
(emp_id NUMBER)
IS
BEGIN
amt := increase(emp_num);
UPDATE employees SET salary = salary+amt WHERE employee_id=emp_id;
END raise_salary;
BEGIN
raise_salary(emp_num);
END calc_sal;
/
What is the outcome when the code is executed?
A.Both blocks compile and execute successfully when called.
B.Both blocks compile successfully but the CALC_SAL procedure gives an error on execution.
C.The CALC_SAL procedure gives an error on compilation because the amt variable should be declared in the RAISE_SALARY procedure.
D.The CALC_SAL procedure gives an error on compilation because the RAISE_SALARY procedure cannot call the stand-alone increase function.
I chose B because i compiled function and procedure and its compile sucssfully but I've tried to invoke(execute) procedure calc_sal and its give me error.
can you Explain to me what's the reason for this error and is my answer correct or false? because in dumps the answer was A
i invoke the procedure with this code :
begin
calc_sal;
end;
and the error i get :
Error report:
ORA-01438: value larger than specified precision allowed for this column
ORA-06512: at "HR.CALC_SAL", line 7
ORA-06512: at "HR.CALC_SAL", line 11
ORA-06512: at line 2
01438. 00000 - "value larger than specified precision allowed for this column"
*Cause: When inserting or updating records, a numeric value was entered
that exceeded the precision defined for the column.
*Action: Enter a value that complies with the numeric column's precision,
or use the MODIFY option with the ALTER TABLE command to expand
the precision.
and employee_id column there is 107 employee Their numbers from 100 to 206.

Answer 1

As Bob's comments state correctly, the code does work correctly, so the quiz answer A is defensible.
You're saying B because you get this error:
ORA-01438: value larger than specified precision allowed for this
column
This is a data problem. The function CALC_SAL() will succeed providing SAL + SAL*10 is <= 999999.99, the maximum value which will fit into a column defined as NUMBER(8,2). So either your table is not defined the way you think it is, or the employee's original salary ishigher then you think it is.
