The right to be forgotten. It’s a concept that sounds great for people who are concerned about their personal information (PII) but it’s a complex issue for developers and data professionals.
I had a fairly puzzling issue today, which took a few minutes to figure out. Some time ago I created a “history” table. This was before temporal tables came out in SQL.
Databases are platforms that are designed to securely store and retrieve your data. Perhaps that’s why they’re called a data “base”? So if your data is in a base, you’d want to lay it out in some logic way.
Continuing the comparison between these two database giants, we dive into the substring function. If you’ve been working with databases for a while, I’m sure you’ve had to parse a string and while you’d think these are the same they work a little different and I think Oracle may surprise you a bit.
It’s been a while since I’ve done a SQL Saturday and I’m happy to be joining the folks in Orlando again this year. I spoke there a couple years ago and had a great time so I’m sure this will not disappoint.
If you happen to be headed to the Orlando, FL area in October, you’ll want to check out this totally FREE SQL Server training event. There are a lot of great speakers and plenty of awesome topics!

I hope to see you there!
It’s Wednesday and that means another SQL/Oracle post. Today we’ll be discussing NULL Values, which can sometimes be a real pain. Don’t worry though there’s a simple solution. Simply replace the NULL value with another.
Today’s topic is Pagination. Paging is a really important feature for web pages and applications. Without it you’d be passing large amounts of data to the application and expecting the application code to figure out which rows it needed to display.
In today’s continuation of the SQL / Oracle series, I thought it’d be nice to show how different the two are for retrieving the top number of rows.
Continuing my series on SQL Server and Oracle, I thought I’d highlight a function that has been in Oracle from some time and has only just recently appeared in SQL Server.
