I recently published a blog post about a portfolio project I am developing using the LAMP stack, Bootstrap 4, jQuery, and the MVC (Model-View-Controller) design pattern in core PHP. In this post, I will introduce an additional feature I integrated into the existing project.

Digital Owl’s Prose End of Year blog post compilation
Like always, I do an end-of-year round-up here on my blog. This year is no different in that aspect, although it has been one crazy year otherwise. With the holidays upon us, I look forward to much-needed time off work, spending time with my family, and catching up on some fantasy novel reading. With that said, here are this year’s top-5 most viewed blog posts from Digital Owls’ Prose. Ironically, for the second year running, none of them were actually written this year! Got to love that evergreen content right!?! Enjoy!
[Keep reading for more SQL database and PHP/Python-centric content >>>]MySQL Window Function Compilation
If you use SQL on a regular basis, then you are well aware that Window Functions are powerful. They allow us to simplify queries that would otherwise be quite the mess. We can provide meaningful insight across rows of data without collapsing the results into a single value. I have written numerous blog posts on Window Functions, many here recently. I decided to make this blog post a compilation of all the Window Function posts I have written, providing a one-stop source for any readers interested in learning more about Window Functions…

Many times, we do not want duplicate rows or values in our SQL tables. On the other hand, in some situations, it does not matter if there are duplicates present. For whatever reason, suppose duplicates have found their way into one of your tables. How can you find them quickly and easily? The ROW_NUMBER() Window function is a fantastic tool to use.

MySQL Shell Python mode for multiple ALTER TABLE statements – easily
There may come a time you need to rename one or more columns in an existing MySQL table for a variety of reasons. Using ALTER TABLE, to rename a column is an easy enough command. But, suppose there are multiple tables in the same database/schema that have the same-named column and all of those columns need to be renamed. That could be a lot of ALTER TABLE statements to type out. Save your energy and time, avoiding all of those ALTER TABLE commands all-together. If you are lucky enough to be working with a MySQL version > 8.0 then the Shell is your salvation. With just a few lines of Python code in \py mode, all of your trouble(s) and headache(s) are no more…
