title: How to insert multiple rows for a single primary key?
body: <p>I have a table named 'Patient_detail'. There are 4 columns in this table. They are:</p>
  
  <ol>
  <li><code>patient_id</code> primary key(not null)</li>
  <li><code>visit_serial_ID</code> primary key(not null)</li>
  <li><code>examination</code></li>
  <li><code>plan</code></li>
  </ol>
  
  <p>Now, how can I insert multiple records in 'examination' and 'plan' column against the   single primary key 'patient_id' and 'visit_serial_ID' of the table 'Patient_detail'?</p>
  
  <p>The datatypes of the fields are as follows:</p>
  
  <ul>
  <li><code>patient_id</code>: number(11)</li>
  <li><code>visit_serial_ID</code>: number(5)</li>
  <li><code>examination</code>: varchar2(50)</li>
  <li><code>plan</code>: varchar2(50)</li>
  </ul>
