title: How to execute callable statement without no output parameters using JdbcDaoSupport
body: <p>My code is this : </p>
  
  <pre><code>public void deleteOption(final int quoteId, final int optionId) {
          this.getJdbcTemplate().execute(new CallableStatementCreator() {
              @Override
              public CallableStatement createCallableStatement(Connection con) throws SQLException {
                  CallableStatement cs = (CallableStatement) con.prepareCall(
                          " BEGIN "+
                          "   NTNQUOTE.QUOTE_TAB.DELETE_QUOTE_OPTION(   ?,?  ); "+
                          " END;");
  
                  cs.setInt(1, quoteId);
                  cs.setInt(2, optionId);
                  return cs;
              }
          }, new CallableStatementCallback&lt;String&gt;() {
              @Override
              public String doInCallableStatement(CallableStatement cs) throws SQLException, DataAccessException {
                  cs.execute();
                  return "SUCCESS";
              }
          });
      }
  </code></pre>
  
  <p>Here there is no output by executing this callable statement but anyway i have to unnecessarily return a string or something,
  Is there any alternative way to do this</p>
