Do you want to display an image on a report in APEX ?
Is the image stored as a BLOB data type in your schema or the blob is returned by some functions?
If so, then displaying the BLOB is not a simple or straight forward task.
Actually it is a simple and straight forward task, as long as you know "the trick" you need to create/defined in your APEX report.
The following steps outlines what (more...)
This blog post will bring you through the steps of how to get Oracle R Enterprise (ORE) to work with APEX.
The reason for this blog posts is that since ORE 1.4+ the security model has changed for how you access and run in-database user defined R scripts using the ORE SQL API functions.
I have a series of blog posts going out on using Oracle Text, Oracle R Enterprise and Oracle Data Mining. (more...)
It has been a busy 12 month. In addition to the day jobs, I've also been busy writing. (More news on this in a couple of weeks!)
Today is a major milestone as my second book is officially released and available in print and ebook formats.
The tile of the book is 'Real Word SQL and PL/SQL: Advice from the Experts'. Check it out on Amazon.
Now that sounds like a very fancy title, (more...)
This is the third blog post of a series on using Oracle Text, Oracle R Enterprise and Oracle Data Mining. Check out the first and second blog posts of the series, as the data used in this blog post was extracted, processed and stored in a databases table.
This blog post is divided into 3 parts. The first part will build on what was covered in in the previous blog post and will expand (more...)

In this blog post I will show you how you use Oracle R Enterprise and the embedded R execution features of ORE to use the text from the (more...)
Over the past few weeks or months (maybe even years) I've had several conversations with various people about why Data Science (or whatever you want to call it) projects fail or never really get started.
Before we go any further perhaps we need to define what 'fail' means in these conversations. Typically fail means that the project doesn't deliver what was hoped for, it got bogged down is some technical or political issues, it did (more...)
When working with SQL or PL/SQL we all know there are some words we cannot use in our code or to label various parts of it. These languages have a number of reserved words that form the language.
Somethings it can be a challenge to know what is or isn't a reserved word. Yes we can check the Oracle documentation for the SQL reserved words
