title: Invalid character string format for type DECIMAL
body: <p>My code was working fine until i closed and ran it again. Now I am getting the exception "Invalid character string format for type DECIMAL.
          at org.apache.derby.client.am.Statement.completeExecute(Unknown Source)"
  at this line of my code:</p>
  
  <pre><code>String sql = "insert into app.customerinfo values (?,?,?,?)";
  PreparedStatement prepSt = conn.prepareStatement(sql);
      /*i am filling in the place holders in prepSt here in this form:
            prepSt.setInt(1, objCust.getCustID()); */
  
               int result = prepSt.executeUpdate();
  </code></pre>
  
  <p>(At the prepSt.executeUpdate line)
  I am new to java, can anyone help me out why I might be getting this exception?</p>
