尝试执行PreparedStatement时发生MySQLSyntaxErrorException [重复]

试试这个，这应该工作：

    try {        connection.setAutoCommit(true);        String sql = "insert into testtable values(?,?)";        PreparedStatement statement = connection.prepareStatement(sql);        statement.setInt(1, userId);        statement.setString(2, userName);        saveStatus  = statement.execute();    } catch (SQLException e) {        e.printStackTrace();    }    return saveStatus;}

PreparedStatement是预编译的语句。您不必在执行时提供sql字符串。
