You have a PreparedStatement with at least one valueholder ?. When you execute it without having set the valueholder with a value using one of the PreparedStatement s setter methods, then you will get this exception. To solve this you obviously need to set the value with the desired value, e.g.

preparedStatement.setString(1, value);

Or if you don t need it at all, then just remove it from the SQL string or create another one for this specific purpose.

For more about PreparedStatements, consult the JDBC tutorial.
