mysql

问题 I've recently upgraded my local machine OS from Ubuntu 18.04 to 20.04, I'm running my MySQL-server on CentOS (AWS). Post upgrade whenever I'm trying to connect to MySQL server it is throwing SSL connection error. $ mysql -u yamcha -h database.yourproject.com -p --port 3309 ERROR 2026 (HY000): SSL connection error: error:1425F102:SSL routines:ssl_choose_client_version:unsupported protocol But if I pass --ssl-mode=disabled option along with it, I'm able to connect remotely. $ mysql -u yamcha -h

问题 I've recently changed my project to use SQLAlchemy and my project runs fine, it used an external MySQL server. Now I'm trying to work with a different MySQL server with SSL CA, and it doesn't connect. (It did connect using MySQL Workbench, so the certificate should be fine) I'm using the following code: ssl_args = {'ssl': {'ca': ca_path}} engine = create_engine("mysql+pymysql://<user>:<pass>@<addr>/<schema>", connect_args=ssl_args) and I get the following error: Can't connect to MySQL server

问题 I can access all of my databases with HeidiSQL, but if I go to the mysql.exe window and use show databases; only 2 of them show up out of 11. These are all databases on 127.0.0.1. Any ideas on why? 回答1: You're logging into HeidiSQL as root , so it's showing you all databases, but you're logging into mysql.exe as the current Windows user (since that's the default), so it's only showing you the databases that that user can see. If you run mysql.exe with --user=root --password=... , it will show

问题 I'm using InnoDb schema on mysql 5.5 . mysql 5.5 guide states: InnoDB uses the in-memory auto-increment counter as long as the server runs. When the server is stopped and restarted, InnoDB reinitializes the counter for each table for the first INSERT to the table, as described earlier. This is a big problem for me. I'm using envers to keep entities audits. I get as many errors as many "last rows" I delete. Suppose I'm starting insert data into an empty table. Suppose to insert 10 rows. Then

问题 In the below code two tkinter entry is created entry1 and entry2 respectively for username and password. What I am looking for is storing the value entered in the tkinter entry to the database table admin_details. But nothing is passed. Also I have no idea in using the condition i.e. " retrieve the values inserted in the tkinter entry and store the data inside the table after the button Login is pressed." Code is something like below: import MySQLdb as mdb from Tkinter import * from

问题 For calculating numbers of downline in binary tree, I am trying the following script by making 2 databases for registration and members downline structure. It works actually. But the members structure database grow very fast. Caused n level in binary tree will generate n records for single user registration. I am just wondering if user register at level 1000 then it will create 1000 record in single user registration. Any other solution for this system? The full long script is : CREATE TABLE
