title: SQL-Oracle Error "date format picture ends before converting entire input string"
body: <p>I insert some value to sql Oracle.</p>
  
  <p>My query in procedure is: </p>
  
  <pre><code>INSERT INTO CHAT_CUSTOMER(customerId, customerName, status, lastLogin, isAdmin)
  VALUES (v_customerId, v_customerName, v_status, to_date(v_lastLogin, 'dd/MON/yyyy hh24:mi:ss'), v_isAdmin);
  </code></pre>
  
  <p>And I run my procedure:</p>
  
  <pre><code>V_CUSTOMERID := '111';
  V_CUSTOMERNAME := 'AAA';
  V_STATUS := 'Busy';
  V_LASTLOGIN := '08/AUG/2015 21:02:44';
  V_ISADMIN := '1';
  </code></pre>
  
  <p>Then I receive error:</p>
  
  <pre><code>ORA-01830: date format picture ends before converting entire input string
  ORA-06512: at line 11
  </code></pre>
  
  <p>I have searched some topics relating to this, but those didn't solve my problem. I add "to_date" but it still doesn't work.</p>
  
  <p>Is there anything wrong here? Please explain for me and help me to solve it.</p>
