问题 I checked different post like: Is there a way to use 'pool_reset_connection' from mysql-connector-python with MariaDB 10.4.7? But I can't solve my isue, I have a program write in python 2.7; now I'm moving everything to python 3 but I got problems with mysql.connector. In this moment I'm using python 3.8.2 and mysql-connector-python==8.0.19 but I try with different version of python 3, but I was getting always the same error on mysql.connector when I try to close the connection.

问题 I'm attempting to connect to my MariaDB database using Connector/J from here, but this fails to work and MariaDB logs ` "[Warning] Aborted connection 12 to db: 'enwikt_parsed' user: 'javawiki' host: 'localhost' (Got an error reading communication packets)". ` It occurs to me that I just assumed Connector/J from MySQL would just work with MariaDB, but now I'm not so sure. I know MariaDB has their own Java API/Connector, but I'm using someone else's code to parse wiktionary, and therefore can't

问题 I am connecting to mysql database via mysql connector and running a simple query to pull a list of IDs. I need to loop over that list and pass them into some other code. For some reason I am getting a list of tuples. Is this expected behavior? If not, what am I doing wrong? Here is the snippet of my code: import mysql.connector conn = mysql.connector.connect(host='127.0.0.1', database='t', user='r', password='pwd') cursor = conn.cursor() query = ( "select id from T where updated < '%s'" %

问题 I am connecting to a mysql server using the following DSN: jdbc:mysql://localhost/my_database?useUnicode=true&characterEncoding=utf-8&serverTimezone=UTC . The problem I'm getting is that the java.sql.Date instance is getting timezone converted to UTC from my local timezone. My application treats dates as timezone agnostic and this is causing a few problems. For instance, I'm in IST (UTC+05:30), when I set some date field to say '2020-01-22' in code, it gets sent to the server as '2020-01-21'.

问题 I'm using mysql-connector-java-5.1.6-bin with jdk 6 currently but I'm moving my project to jdk 8 do I need to download different version of this jar file? 回答1: If you want use JDK 8, you need the latest version of mysql connector, Connector/J 8.0 From the What's New in Connector/J 8.0? page: It is a MySQL driver for the Java 8 platform. For Java 7 or earlier, use Connector/J 5.1 instead. 回答2: You don't require Connector/J 8.0 to run on JRE 8. Connector/J 5.1 works too but 5.1 is getting much

问题 I installed XDevAPI for connecting mysql and nodejs. but it throw error like "The server gone away" because i am using 3306 port. how to solve this. 回答1: Port 3306 defaults to the classic MySQL Wire Protocol. The MySQL X DevAPI Connector for Node.js only supports the X Protocol, which is implemented by the X Plugin (by default on port 33060). You can change this by updating the mysqlx_port server variable or using the --mysqlx-port= option when starting the server. If you want to use the X

问题 In short, what are the steps that one needs to take in order to modify the source of the connector and install it in Windows? I have the MySQL Connector/.NET Version 6.1.2 installed on my machine, but I'm getting an exception for every DateTime with a value of '0000-00-00'. This exception breaks my application.
