Video : SQLCL and Liquibase : Deploying Oracle Application Express (APEX) Applications

In today’s video we’ll give a quick demonstration of deploying an APEX application using the SQLcl implementation of Liquibase.

I Know what you’re thinking. Didn’t I do this video two weeks ago? The answer is yes and no. This video is very similar to the Liquibase video I did two weeks ago, but that was using the Liquibase Pro client. This video uses the SQLcl implementation of Liquibase, and more specifically the runOracleScript tag to achieve the same thing.

The video is based on this article, which has an example of deploying an APEX workspace and an APEX application.

If you are new to Liquibase and SQLcl, you might find it easier to start with these.

The stars of today’s video are the offspring of Jeff Smith. I had been annoying Jeff on Twitter DMs while he was meant to be on holiday, so I agreed to pay him back by turning his children into international megastars. I take no responsibility for how they handle the fame! πŸ˜‰

If you want the copy/paste examples and the test files, you can get them from this article.

Yet another reason why you should always install APEX in your databases.

Video : Returning REF CURSORs from PL/SQL : Functions, Procedures and Implicit Statement Results

Today’s video is a demonstration of returning REF CURSORs from PL/SQL using functions, procedures and implicit statement results.

I was motivated to do this after a conversation with my boss. He’s from a .NET and SQL Server background, and was a bit miffed about not being able to use a SELECT to pass out variable values from a procedure, like you can in T-SQL. So I piped up and said you can using Implicit Statement Results and another myth was busted. I guess most PL/SQL developers don’t use this, and I don’t either, but you should know it exists so you can be a smart arse when situations like this come up. πŸ™‚

The video is based on these articles.

The star of today’s video is Bryn Llewellyn of PL/SQL fame, and more recently Yugabyte.

Video : SQLcl and Liquibase : Automating Your SQL and PL/SQL Deployments

In today‘s video we’ll give a quick demonstration of applying changes to the database using the Liquibase implementation in SQLcl.

The video is based on this article.

You might also find these useful. The secure external password store is a good way to make connections with SQLcl. If you support a variety of database engines, you may prefer to use the regular Liquibase client.

Video : Decoupling to Improve Performance

In today’s video we demonstrate how to cheat your way to looking like you’ve improved performance using decoupling.

This was based on the following article.

This came up in conversation a few days ago, so I thought it was worth resurrecting this demo. It doesn’t really matter what tech stack you use, the idea is still the same.
