OpenLampTech issue #53 – Substack Repost

Now that OpenLampTech is one year old, I have a point to prove. That I can consistently provide the MySQL, PHP, and LAMP stack communities with a valuable newsletter publication. Challenge accepted. This week’s issue is full of great content so give it a read!

AlmaLinux MySQL Workbench

AlmaLinux doesn’t natively support MySQL Workbench but these notes will help you install it. The great news is that MySQL Workbench works perfectly once you’ve installed all the dependent libraries. It’ll look like the following:

Disclaimer of sorts:

AlmaLinux is an open-source, community-driven project that intends to fill the gap left by the demise of the CentOS stable release. AlmaLinux is a 1:1 binary compatible fork of RHEL® 9 and it is built by the AlmaLinux OS Foundation as a standalone, completely free OS. The AlmaLinux OS Foundation will support future RHEL® releases by updating AlmaLinux. Ongoing development efforts are governed by the members of the community.

You can download MySQL Workbench from the following website:

https://dev.mysql.com/downloads/workbench

When you open this page, select the Red Hat Enterprise Linux 9 / Oracle Linux 9 (x86, 64-bit), RPM Package from the dropdown …

AlmaLinux MySQL+Perl

A quick primer on Perl programs connecting to the MySQL database. It’s another set of coding examples for the AlmaLinux instance that I’m building for students. This one demonstrates basic Perl programs, connecting to MySQL, returning data sets by reference and position, dynamic queries, and input parameters to dynamic queries.

  1. Naturally, a hello.pl is a great place to start:
    #!/usr/bin/perl
    
    # Hello World program.
    print "Hello World!\n";
    

    After setting the permissions to -rwxr-xr-x. with this command:

    chmod 755 hello.pl
    

    You call it like this from the Command-Line Interface (CLI):

    ./hello.pl
    

    It prints:

    Hello World!
    
  2. Next, a connect.pl program lets us test the Perl::DBI connection to the MySQL database.
    #!/usr/bin/perl
    
    # Import libraries.
    use strict;
    use warnings;
    use v5.10;     # for …

The OpenLampTech Developer Newsletter is One Year Old

The OpenLampTech developer newsletter is one year old! I honestly don’t know where the past year went. Obviously, I had my nose buried in some fantastic content since OpenLampTech publishes mostly curated newsletters.

I tell you though, don’t think it isn’t a challenge adding your own thoughts and commentary to someone else’s great content because it definitely is.

I plan to continue publishing curated content in OpenLampTech but, also cover tech reporting and news-related topics that are within the MySQL, PHP, and LAMP stack ecosystems.

There seems to always be plenty to talk about in these areas so a shortage of topics won’t be the issue (I don’t think).

While MySQL has supported UNION and UNION ALL commands, there were no INTERSECT or EXCEPT commands in the language. This often involved work-around queries. However, MySQL now does support the INTERCEPT and EXCEPT set operators.

For the example queries, I am using 2 simple tables with arbitrary data.
