while executing below code it showing error

Question

This is my pl/sql program:

 declare
   m_no      emp.emp_no%rowtype;
   m_name    emp.emp_name%rowtype;
   m_address emp.address%rowtype;
   cursor raju is 
     SELECT emp_no,
            emp_name,
            address 
       from emp;
 begin
   open raju;
   loop
     fetch raju 
      into m_no,
           m_name,
           m_address;
     dbms_output.put_line(m_no ||''||m_name||''||m_address);
     EXIT WHEN raju%notfound;
   end loop;
   close raju;
 end;

while executing above code am getting error

but I didn't get where it showing and where it error occurring. Any one suggest me please.

Answer 1

Your variable declaration is wrong.

Since you are selecting and storing the columns separately, you should declare it using %TYPE attribute.

m_no      emp.emp_no%type;
m_name    emp.emp_name%type;
m_address emp.address%type

%ROWTYPE attribute is used if you are using single variable to store all columns.

m_emp emp%rowtype
