  <p>3 3 456987321 </p>
  
  <p>4 3 465987321 </p>
  
  <p>5 3 321651213 </p>
  
  <p>If i pass the input as 'emp01', i need to get all the information from parent and child tables </p>
  
  <p>Parent table ID and Child emp_id forms the foreign key relationships</p>
  
  <p>How can this be achieved? </p>
