Examine the following command to create the table EMPLOYEES_TEMP and the PL/SQL block.

CREATE TABLE employees_temp (empid NUMBER(6) NOT NULL,

deptid NUMBER(6) CONSTRAINT c_emp_deptid CHECK (deptid BETWEEN 100 AND 200),

salary Number(8),

deptname VARCHAR2(30) DEFAULT #39;Sales#39;)


SUBTYPE v_emprec_subtype IS employees_temp%ROWTYPE; v_emprec v_emprec_subtype;


v_emprec.empid := NULL; v_emprec.salary := 10000.002; v_emprec.deptid := 50;

Which statements are true about the above PL/SQL block? (Choose two.)

  1. V_EMPREC.DEPTNAME would display a null value because the default value is not inherited.

  2. Assigning null to V_EMPREC.EMPID would generate an error because the null constraint is inherited.

  3. Assigning the value 1000.002 to V_EMPREC.SALARY would generate an error because of the decimal.

  4. Assigning the value 50 to V_EMPREC.DEPTID would work because the check constraint is not inherited.
