Question

基本上，问题出在标题中，产生这种情况的确切顺序如下。出于某种原因，带有LIMIT 2的SELECT很好，但带有LIMIT 1的SELECT会产生多个警告并关闭连接。

警告文本在阅读之后，在我的情况下也没有任何意义 - 毕竟，我并没有尝试调用某些PHP函数，我正在进行简单的数据库调用。

感谢所有能帮助我做出正面或反面的人。

from twilio.rest import Client

account_sid = "~~~"
auth_token = "~~~"
client = Client(account_sid, auth_token)

call = client.messages.create(
    to="+821012341234",# korea phone number : 010-1234-1234
    from_="+18442414836", # United States phone number :(844) 241-4836
    body="    this is message text contents    "
)

| Warning | 1287 | 'COM_FIELD_LIST' is deprecated and will be removed in a future release. Please use SHOW COLUMNS FROM statement instead |

由于某种原因，它可以按预期工作：

SELECT `id` FROM `sthng` WHERE `blaid`=126435217;
+---------+
| id      |
+---------+
| 3204457 |
+---------+
1 row in set (0.00 sec)

由于某种原因，我仅在mysql控制台客户端上遇到此问题。这个问题最近弹出，我确实有5.7.23-log版本。应该打开一个错误报告。

一个简单的选择后，Mysql关闭30k COM_FIELD_LIST警告的连接
