Getting error while Executing Package

Question

Table Structure:

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


        

Answer 1

The package needs a specification (i.e. a separate interface definition) as the error message says. You would have to add something like before the definition of the package body (i.e. its implementation):

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