With MySQL Cluster you can now from version 8.0.31 use transparent data encryption (TDE). Together with the encrypted backup feature it encrypts all data persisted on disk for tables that uses the Ndb storage engine in MySQL. This complements other already existing features that encrypts data at rest in MySQL.

TDE encryption uses XTS-AES and is transparent to applications accessing the data via MySQL or directly using the C++ NdbAPI. The same application can run unmodified whether …

With the latest MySQL release (8.0.31), MySQL adds support for the SQL standard INTERSECT and EXCEPT table operators.

Let’s have a look how to use them.

We will use the following table:

CREATE TABLE `new` (
  `id` int NOT NULL AUTO_INCREMENT,
  `name` varchar(20) DEFAULT NULL,
  `tacos` int DEFAULT NULL,
  `sushis` int DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB

For our team meeting, we will order tacos and sushi’s.

Each record represent the order of each team member:

select * from new;
+----+-------------+-------+--------+
| id | name        | tacos | sushis | …

I continue to dig up and share this simple approach for production data masking via SQL to create testing data sets. Time to codify it into a post.

Rather than generating a set of names and data from tools such as Mockaroo, it is more practical to use actual data for a variety of testing reasons.

The SQL below is a self-explanatory approach of removing Personal Identifiable Information (PII), but keeping data relevant. I use this approach for a number of reasons.

• We are using production data rather than synthetic data. Data volume, distribution, and additional column values are realistic. This is a subset of an example, but dates and locations are therefore realistic
• Indexes (and unique indexes) still work, and distribution across the index is adequate for searching. Technically the index …

tl;dr In retrospect, it was inevitable. Formal support for TypeScript applications has landed in Connector/Node.js. Type definitions for the entire public API are now available to ensure developers are able to leverage some goodies unlocked by traditional statically-typed languages such as autocompletion, integrated refactoring, visual type-related hints and compile-time errors. How to TypeScript? TypeScript is a […]

As of MySQL v8, we have Common Table Expressions (CTEs) or the WITH clause available. I recently learned how to use the WITH clause in an INSERT statement, similar to INSERT with SELECT. Like always, I enjoy sharing what I learn so let’s all learn together…

For the sake of simplicity (and my sanity) I’m using this arbitrary sample data:

SELECT *
FROM auto_test;

We can use the WITH clause to generate a …
