mysql in函数拼接条件问题

Question

String[] orderIds = query.getOrderId().split(",");

    StringBuffer buffer = new StringBuffer();
    for (String orderId : orderIds) {
        buffer.append(orderId).append(",");
    }
    buffer.deleteCharAt(buffer.length() - 1);
    String sql = "select order_id,pay_status from order_info where order_id in ("+buffer.toString()+")";
    List<OrderInfoTo> list = jdbcService.queryEntityList(OrderInfoTo.class,sql);
    

抛出异常：
PreparedStatementCallback; bad SQL grammar [select order_id,pay_status from order_info where order_id in (170606100349,170606100376,170606100396)]; nested exception is com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Unknown column 'ys170606100349' in 'where clause'

这种方法一直在用，都没有抛过异常，突然今天我在另一个需求做的时候使用这种方法查询，突然抛异常了，怎么解决，原因是什么

Answer 1

Unknown column 'ys170606100349' in 'where clause' 他都说不识别的ys170606100349是不是ys这个的缘故
你打印sql看看能不能运行
