This is one area that was not a surprise to me coming from Db2 to MySQL, as I’ve had to deal with people confused in the other direction for years. Essentially, MySQL allows a syntax for GROUP BY that Db2 and most RDBMSes do not allow.… Read the restContinue reading »
Working in technology, I’ve heard a number of things about ChatGPT from various news sources.
I was particularly interested hearing some teachers saying it was the end of being able to properly detect students cheating when writing papers. Then I heard a teacher talking about how this was the new ‘calculator’ that teachers need to learn how to leverage in their curriculums.… Read the restContinue reading »
Every RDBMS has areas where the differences from other RDBMSes are noticeable, and this is one of them between Db2 and MySQL. Most RDBMSes have quirks to the way SQL is written, and this is certainly true of Db2 where some things were there before the SQL-92 standard or other standards existed.… Read the restContinue reading »

CREATE TABLE or
CREATE INDEX statements, but how that data is generally structured on disk, both logically and physically.… Read the rest
I’m a couple of months into working with MySQL, and thought I’d share some resources and thoughts on what I’m learning and what is working. At least half of that time was dedicated to a very in-depth onboarding process that barely mentioned a database at all in about a month of content, so it’s closer to a month in.… Read the restContinue reading »
Many RDBMSes have similar structures and concepts. In this post, I’m going to compare and contrast IBM Db2’s concept of a clustered index and MySQL’s concept of a clustered index.
Index vs. Clustered Index
An index is generally a way of organizing data in a way that it will be quicker to access than scanning through all of a table.… Read the restContinue reading »

As part of my publicly shared data science journey, I’ve continued to read job postings, even while reasonably satisfied with my current job.… Read the restContinue reading »
