JSON

In today’s video we demonstrate the JSON data type, introduced in Oracle database 21c.

The video is based on this article.

• JSON Data Type in Oracle Database 21c

It assumes knowledge of existing JSON support in the Oracle database. If you are not familiar with the functionality Oracle have been including in the database since Oracle 12c, you might want to check out these.

What better way to start a new week than with a cheesy title to my blog post!

But there is method to my unstructured madness today as we talk about the TREAT function, available from 18C for JSON data. As many of us will already know it is possible to dive into JSON data and extract information from its components as if they were relational columns using the very cool dot notation

In order to do so, we need to be a little generous to the database by letting it know that the contents of a unstructured column such as a CLOB is truly correct JSON data.

I will start with a table with a simple CLOB which does indeed contain valid JSON but I have not let the database know about that fact:

Today’s video is a quick demonstration of using the APEX_DATA_PARSER package to convert simple CSV, JSON, XML and XLSX data into rows and columns.

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

• APEX_DATA_PARSER : Convert simple CSV, JSON, XML and XLSX data as rows and columns

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

In today’s video we’ll demonstrate how to include hyperlinks in JSON output delivered by Oracle REST Data Services (ORDS).

This is based on this article, which includes some more complete examples.

• Oracle REST Data Services (ORDS) : Including Hyperlinks in JSON Output

Good API design is not as simple as you might think, and making sure you pass back relevant information, like URLs for navigating through the services and maybe even service documentation links can make things a lot clearer.

In today’s video we look at the OAuth Implicit flow for Oracle REST Data Services.

This goes together with a previous video about first-party authentication here.

Both videos are based on parts of this article.

• Oracle REST Data Services (ORDS) : Authentication

There are loads of other ORDS articles here.

Today’s video is a run through the REST Enabled SQL functionality in Oracle REST Data Services (ORDS).

I wasn’t originally planning on doing this video yet, but the subject of REST Enabled SQL came up a couple of times in the last few days, so I thought I would alter my schedule.

This video is based on the following article, where you can find a lot more examples than are present in the video.

• Oracle REST Data Services (ORDS) : REST Enabled SQL

There is a lot more information about ORDS generally in these articles.
