Slides and Workbooks From Oracle OpenWorld & CodeOne


First of all, thanks to everyone who attended my sessions at the recent Oracle OpenWorld and Code One in San Francisco. It was a great privilege to be allowed to make a number of presentations.

All of the workbooks and scripts from the hands-on labs (HOL) and the slides from the talks have been made available at OpenWorld’s and Code One’s session catalogues. You can download the files by using the OpenWorld catalog searching for my name or the session number (see below). Click on the download icon for each of the presentations you are interested in.

Quickly Load JSON Data into The MySQL Document Store with util.importJson

With new MySQL Shell 8.0.13 comes a new way to quickly load JSON data sets very quickly.  In a past blog and in several talks I have shown how to use the shell with the Python mode to pull in the data.  But now there is a much faster way to load JSON

Load JSON Quickly Start a copy of the new shell with mysqlsh. Connect to your favorite server \c dave@localhost and then create a new schema session.createSchema('bulk'). Then point you session to the schema just created with \use bulk.  Version 8.0.13 has a new utility function named importJson that does the work.  The first argument is the path to the data set (here the MongoDB restaurant collection) and the second allows you to designate the schema and collection where you wish to have the data stored.  In this example the data set was in the downloads directory of my laptop and I wanted to put it in the newly created 'bulk' schema …

MySQL Books - 2018 has been a very good year

Someone once told me you can tell how healthy a software project is by the number of new books each year.  For the past few years the MySQL community has been blessed with one or two books each year. Part of that was the major shift with MySQL 8 changes but part of it was that the vast majority of the changes were fairly minor and did not need detailed explanations. But this year we have been blessed with four new books.  Four very good books on new facets of MySQL.

Introducing the MySQL 8 Document Store is the latest book from Dr. Charles Bell on MySQL.  If you have read any other of Dr. Chuck's book you know they are well written with lots of examples.  This is more than a simple introduction with many intermediate and advanced concepts covered in detail.

JSON Paths and the MySQL JSON Functions

I wrote MySQL and JSON: A Practical Programming Guide to help developers find their way around the MySQL JSON data type and the supporting functions. The MySQL Documentation on the subject is very good but I had to puzzle through the examples to see how things worked.  I might be a bit 'thick' but good examples always make things easier.  Others seem to have similar difficulties.

MySQL and JSON a Practical Programming Guide should be on your desk as a handy reference to MySQL's JSON data type.

 There was a recent post on …

MySQL at Oracle Open World and Oracle Code One Oct 22-25 2018 !

This year again, the MySQL Team is eager to participate in the Oracle Open World conference. This is a great opportunity for our engineers and the entire MySQL Team to highlight what we’ve done, and also what we are working on.

30 mins with MySQL JSON functions

JSON (JavaScript Object Notation) is a popular way for moving data between various systems, including databases. Starting with 5.7 MySQL implemented a native JSON data type and a set of JSON functions that allows you to perform operations on JSON values.

De-Normalization of Your Database with JSON

One of the humbling things about working at Oracle with the various MySQL personnel is that you are often blown away by something one of them says or does.  And that is on a regular basis.  In this case it is Dr. Charles Bell who gave a great series of presentations last June at the Southeast Linuxfest.
In particular he presented in a full formed state some ideas that had been rattling around in my  skull (but no way near as coherent) on how to take advantage of the MySQL JSON data type.  Below are his points from his slide deck.  I was reviewing my notes from his presentation when I realized that this information really needs to be more widely disseminated.   And I would like your feedback on these ideas?
1.. We can use a JSON field to eliminate one of the issues of traditional database solutions: many-to-many-joins

  • This allows more freedom to store unstructured data (data with pieces …
