Error phenomenon:
ERROR 1045 (28000): Access denied for user 'ODBC'@'localhost' (using password: NO)
ERROR 1045 (28000): Access denied for user 'ODBC'@'localhost' (using password: YES)
Under Windows, the solutions to the above two errors have been tested by me personally and are effective. I now share the solutions as follows:
1. Find the configuration file my.ini and open it. You can choose to open it with Notepad.
2. After opening, search for the mysqld keyword. After finding it, add skip-grant-tables under mysqld, save and exit. PS: If you are prompted not to save, you can cut the file to the desktop, save the changes, and then copy it to the mySQL directory.
3. Restart mySQL after saving.
4. Run cmd, enter mysql -u root -p to log in without a password. When password: appears, just press Enter to enter.
5. Enter the mysql database:
1).Switch database: mysql> use mysql;Database changed
2).Set a new password for the root user: mysql> update user set password=password("123456") where user="root";
3). Refresh the database: mysql> flush privileges;
4).Quit mysql: mysql> quitBye
PS: 123456 is the new password. Users can change it to their own password according to their needs.
6. After making the changes, modify the my.ini file again, delete the "skip-grant-tables" line we just added, save and exit, and then restart the mysql service.
The above is the entire content of this article. I hope it will be helpful to everyone in solving the MySQL ERROR 1045 (28000) error problem.

MySQL partitioning improves performance and simplifies maintenance. 1) Divide large tables into small pieces by specific criteria (such as date ranges), 2) physically divide data into independent files, 3) MySQL can focus on related partitions when querying, 4) Query optimizer can skip unrelated partitions, 5) Choosing the right partition strategy and maintaining it regularly is key.

How to grant and revoke permissions in MySQL? 1. Use the GRANT statement to grant permissions, such as GRANTALLPRIVILEGESONdatabase_name.TO'username'@'host'; 2. Use the REVOKE statement to revoke permissions, such as REVOKEALLPRIVILEGESONdatabase_name.FROM'username'@'host' to ensure timely communication of permission changes.

InnoDB is suitable for applications that require transaction support and high concurrency, while MyISAM is suitable for applications that require more reads and less writes. 1.InnoDB supports transaction and bank-level locks, suitable for e-commerce and banking systems. 2.MyISAM provides fast read and indexing, suitable for blogging and content management systems.

There are four main JOIN types in MySQL: INNERJOIN, LEFTJOIN, RIGHTJOIN and FULLOUTERJOIN. 1.INNERJOIN returns all rows in the two tables that meet the JOIN conditions. 2.LEFTJOIN returns all rows in the left table, even if there are no matching rows in the right table. 3. RIGHTJOIN is contrary to LEFTJOIN and returns all rows in the right table. 4.FULLOUTERJOIN returns all rows in the two tables that meet or do not meet JOIN conditions.

Common security vulnerabilities in MySQL include SQL injection, weak passwords, improper permission configuration, and unupdated software. 1. SQL injection can be prevented by using preprocessing statements. 2. Weak passwords can be avoided by forcibly using strong password strategies. 3. Improper permission configuration can be resolved through regular review and adjustment of user permissions. 4. Unupdated software can be patched by regularly checking and updating the MySQL version.

Identifying slow queries in MySQL can be achieved by enabling slow query logs and setting thresholds. 1. Enable slow query logs and set thresholds. 2. View and analyze slow query log files, and use tools such as mysqldumpslow or pt-query-digest for in-depth analysis. 3. Optimizing slow queries can be achieved through index optimization, query rewriting and avoiding the use of SELECT*.
