MySQL Server 8.0.33 Update Overview! (MySQL for Beginners)
In this short sql tutorial we’ll walk you through one of the newest MySQL server updates – updates to MySQL server version 8.0.33. This mysql for beginners video will be useful for beginners as well as for advanced DBAs alike.
The biggest thing in this mysql upgrade is that mysql is deprecating collations and that mysql user-defined collations will be removed in a future release. If we have any occurrence of the COLLATE statement with a user-defined part of the sql query or if we try to set a mysql server, mysql database, or mysql connection collation, we will face a warning in the log.
In mysql server, user-defined collations will also be removed in a future release.
Let us know what you think about this new mysql server update in the comment section down below, and until next time.
