SQL

In today’s video we give a quick demonstration of using Resource Manager to cancel a long running SQL statement.

This video is based on a series of articles from Oracle 8i to the present day. There is an example here.

• Resource Manager : Runaway Query Management

Although there are aspects of it throughout most of the Resource Manager articles on the website.

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.

In today’s video we’ll give a quick demonstration of Hybrid Partitioned Tables, introduced in Oracle Database 19c.

The video is based on this 19c article.

• Hybrid Partitioned Tables in Oracle Database 19c

The video only has a single example using external partitions pointing to CSV data. The article also includes and example using a Data Pump file.

Today’s video is a quick demonstration of deploying an Oracle Application Express (APEX) application using Liquibase.

The video is based on a new article of the same name, which covers the deployment of both APEX workspaces and APEX applications using Liquibase.

There are good reasons for NoSQL and semi-structured databases. And there are also many mistakes and myths. If people move from RDBMS to NoSQL because of wrong reasons, they will have a bad experience and this finally deserves NoSQL reputation. Those myths were settled by some database newbies who didn’t learn SQL and relational databases. And, rather than learning the basics of data modeling, and capabilities of SQL for data sets processing, they thought they had invented the next generation of persistence… when they actually came back to what was there before the invention of RDBMS: a hierarchical semi-structured data model. And now encountering the same problem that the relational database solved 40 years ago. This blog post is about one of those myths.

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.

• SQLcl : Automating Your SQL and PL/SQL Deployments using the SQLcl implementation of Liquibase

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.
