title: sql INSERT INTO with same ID Number
body: <p>I'd like to make a sql table something like this.</p>
  
  <p>Patient Num | Trial Number | Trial Date</p>
  
  <pre><code> 1      |      1       | 12/19/2014
   1      |      2       | 12/20/2014
   2      |      1       | 12/19/2014
   3      |      1       | 12/19/2014
  </code></pre>
  
  <p>I can do this with different patient numbers, but I can't do with same patient number. So I'd like to make this table with the same Patient Number but different trial numbers. My code is</p>
  
  <pre><code>cmd.CommandText = "INSERT INTO PatientTestInfo(PatientNum, TrialNum, TrialDate)" &amp; _
              "VALUES(" &amp; PtNum_TextBox.Text &amp; ",'" &amp; TrialNum_TextBox.Text &amp; "','" &amp; TrialDate_PK.Value &amp; "')"
          cmd.ExecuteNonQuery()
  </code></pre>
  
  <p>Any ideas?</p>
