Getting error while Executing Package

Question

Table Structure:

Name       Null Type         
---------- ---- ------------ 
DPT_NO          NUMBER       
SALARY          NUMBER(10)   
PERIOD          VARC         


        

Answer 1

You're missing the declaration of the package. The idea is to separate the declaration of the package ("the header", if you will), so other packages/procedures/functions can compile against it from the body (the implementation).

In your case, you'd need something like:

CREATE OR REPLACE package salary_sal AS
   PROCEDURE find_sal(c_dpt_no salary.dpt_no%TYPE);
END salary_sal;

Now, once the package is declared, you can create its body:

CREATE OR REPLACE package body salary_sal AS
   PROCEDURE find_sal(c_dpt_no salary.dpt_no%TYPE) IS
   c_sal salary.salary%TYPE;
   BEGIN
      SELECT salary INTO c_sal
      FROM salary
      WHERE c_dpt_no= 108;
      dbms_output.put_line('Salary: '|| c_sal);
   END find_sal;
END salary_sal;
