Retrieve Data From Two Tables

Use of cursor (Explicit) in SQL 


Declare
Cursor emp_cur is
Select emp.ename,dept.dname,dept.deptno
From emp,dept
Where emp.deptno = dept.deptno;
Begin
For emp_rec in emp_cur loop
If emp_rec.deptno = 30 then
Dbms_output.put_line('Employee'||'  '||emp_rec.ename||'  '||'work in the'||'  '||emp_rec.dname||'  '||'Department');
End if;
End loop;
End;

So find these Result:

Employee  ALLEN  work in the  SALES  Department
Employee  WARD  work in the  SALES  Department
Employee  MARTIN  work in the  SALES  Department
Employee  BLAKE  work in the  SALES  Department
Employee  TURNER  work in the  SALES  Department
Employee  JAMES  work in the  SALES  Department
