I’ve been using MySQL 8 on Linux for a couple years but the Linux repository version didn’t install the new MySQL Shell. So, I discovered the new MySQL Shell when I installed MySQL 8 (8.0.21) on Windows to teach my student how to use it to learn SQL commands. I encourage you to read the full MySQL Shell document.

The following is a tutorial to provision a student user and studentdb database in MySQL. It uses the MySQL Shell (mysqlsh) and stages for uploads of comma-separated values files.

After installing MySQL on the Windows 10 OS, open the Window OS Command Line Interface (CLI) shell by entering the following in the search field at the bottom left:

cmd

It launches a CLI interface to the Windows OS. The cmd (command) utility opens the CLI in the following …

While preparing a set of student instructions to create a MySQL 8 (8.0.21) Windows 10 instance I found an error with LOAD command and the --secure-file_priv variable set in the my.ini file. After granting the global FILE permission to the previously provisioned student user:

GRANT FILE ON *.* TO 'student'@'localhost';

Any attempt to run the following command failed:

LOAD DATA INFILE 'C:\ProgramData\MySQL\MySQL Server 8.0\Uploads\avenger.csv'
INTO TABLE avenger
FIELDS TERMINATED BY ','
ENCLOSED BY '"'
ESCAPED BY '\\'
LINES TERMINATED BY '\r\n';

and, raise this error message:

ERROR: 1290: The MySQL server is running with the --secure-file-priv option so it cannot execute this statement

The following covers my exploration to try and fix this error without removing a designated directory for secure file uploads. While MySQL 5.7 …

We all like when error messages are descriptive and give a clear idea about what is happening; however, there are some cases when a few possible reasons lay behind one error message. “MySQL server has gone away” is one of them. Most of the cases when the error occurs are described in MySQL documentation, but it can get tricky. And here, I’d like to talk about “tricky”.

There are only a few major cases when this happens:

1. MySQL Thread Was Killed by an Administrator or a Utility Such as pt-kill

The manual intervention is likely to be intermittent and, as it is a one-time thing in certain situations (e.g., a bad long-running query), probably would be known to a DBA. Pt-kill might be less noticeable, as it is often left running as a workaround to prevent those bad long queries from taxing system resources. Checking the system …

If you are running MySQL on premise, it’s maybe the right time to think about migrating your lovely MySQL database somewhere where the MySQL Team prepared a comfortable place for it to stay running and safe.

This awesome place is MySQL Database Service in OCI. For more information about what MDS is and what it provides, please check this blog from my colleague Airton Lastori.

One important word that should come to your mind when we talk about MDS is SECURITY !

Therefore, MDS endpoint can only be a private IP in OCI. This means you won’t be able to expose your MySQL …

A blog series about ProxySQL and Galera…

This post is the first of a series of blogposts on how to easily use ProxySQL to scale-out your application’s database workload on a Galera cluster. This series will explore the main concepts in configuring ProxySQL for Galera across three articles as follows:

– A first introductory post describing the minimal configuration needed for ProxySQL to monitor and manage a Galera Cluster.
– A second post describing how to setup a read/write split configuration for our Galera Cluster, using ProxySQL query rules.
– A third and final post with examples on specific cluster configuration options and more detailed explanations on why and how ProxySQL changes the nodes states based on configuration changes and monitored variables. Requirements

To illustrate how to configure ProxySQL for a Galera Cluster we will use a sample Galera Cluster …

The MySQL UNIQUE constraint is often used in a column definition in which we need each value for that column to be distinct from the others. Perhaps it is an email column for an on-line registration form and we want to ensure that users cannot register twice for an account using the same email. Whatever the case may be, UNIQUE is there to help us ensure this type of data integrity or business requirement. What if the target table already exists and you determine you need to add a UNIQUE constraint to an existing column? In this post, I will cover 2 ways you can implement a UNIQUE constraint on existing columns using the phpMyAdmin web interface…

In this post I describe the various steps that allowed me to reach 3.6 million queries per second on a single VM instance using MySQL 8.0 with the help of Dynimize.

It's not every day that you get to break a record. So when I discovered that you can now rent by the hour massive instances within Google Compute Cloud that support 224 virtual cores based on AMD EPYC 2 Rome processors, I had to jump at the opportunity to see what kind low hanging fruit might be out there. Low and behold I found it! Oracle's performance record for MySQL on a single server stands at 2.1M QPS without using Unix sockets, and 2.25M QPS with Unix sockets. Seeing that they published this 3 years ago on Broadwell based …
