Recent improvements to MySQL Database Service: Support for version 8.0.28, MySQL version selection, MySQL simplified state management after maintenance events, and MySQL Database Service Data Masking and De-Identification Functions.

If you plan to deploy a Drupal site to OCI using MySQL Database Service, there is a very easy way to perform that deployment: using OCI’s Resource Manager ! As you know, security is something very important for Oracle in OCI, therefor, exposing the database on the Internet is not allowed. Even if you are […]

Incremental backups of MySQL, specifically for the InnoDB engine, are taken by copying modified pages from the previous backup.

The brute force method takes backups by scanning every page in tablespace file in the server data directory is an expensive operation. The time required for incremental backups increases as the data-dir size increases.

To solve this problem, Percona Server for MySQL introduced a  “Changed Page Tracking” feature in 5.6 that enables Percona XtraBackup (PXB) to copy only the modified pages required for incremental backups. See the Percona XtraBackup Documentation for more information. …

As many know, I’ve adopted Learning SQL by Alan Beaulieu as a core reference for my database class. Chapter 7 in the book focuses on data generation, manipulation, and conversion.

The last exercise question in my check of whether they read the chapter and played with some of the discussed functions is:

1. Use one or more temporal function to write a query that convert the ’29-FEB-2024′ string value into a default MySQL date format. The result should display:

   +--------------------+
   | mysql_default_date |
   +--------------------+
   | 2024-02-29         |
   +--------------------+
   1 row in set, 1 warning (0.00 sec)
   

If you’re not familiar with the behavior of MySQL functions, this could look like a difficult problem to solve. If you’re risk inclined you would probably try the STR_TO_DATE function but if you’re not risk inclined the description of the %m specifier might suggest you …

Sometimes you hear from some new developers that MySQL only makes case insensitive string comparisons. One of my students showed me their test case that they felt proved it:

SELECT STRCMP('a','A') WHERE 'a' = 'A';

Naturally, it returns 0, which means:

• The values compared by the STRCMP() function makes a case insensitive comparison, and
• The WHERE clause also compares strings case insensitively.

As a teacher, you’re gratified that the student took the time to build their own use cases. However, in this case I had to explain that while he was right about the STRCMP() function and the case insensitive comparison the student used in the WHERE clause was a choice, it wasn’t the only option. The student was wrong to conclude that MySQL couldn’t make case sensitive string comparisons.

I modified his sample by adding the required BINARY keyword for a case sensitive comparison in …

In this post, I describe you how to deploy WordPress on OCI using MySQL Database Service. I wrote some Terraform recipes that you can find on my GitHub repository: oci-wordpress-mds. I will show how easy it’s to deploy directly from OCI’s dashboard using Resource Manager’s stack. I will also share the recent additions. The first think […]
