Learn SQL in this FREE 12-part boot camp. It will help you get started with Oracle Database and SQL. The course is a series of videos to teach you database concepts, interactive SQL tutorials, and quizzes to reinforce the ideas. Complete the course to get your free certificate.
Columns and Data Types
When defining columns in a table, you need to choose a data type for them. This class you about the common SQL data types and their uses.
Select and Where
Learn how to use a select statement to get you rows from your database. And filter these data using a where clause.
Select, Joins and Group By Review
A chance to recap and catch up on modules 5-7 covering the basics of SQL queries: select, joins and group by.

2. Databases for Developers: Next Level
A FREE 10-part tutorial to help you improve your Oracle SQL skills.
This course continues where Databases for Developers: Foundations left off, taking you further on your SQL journey.
The class consists of a series of videos introducing concepts, interactive coding sections, and quizzes to test your understanding.
The first module is now open. Join us for SQL-awesomeness! 🙂
Order By and Top-N
To guarantee your results are sorted in a particular way, you must use an order by clause. This module shows you how this works. It goes on to explain how to filter results to show the first N rows of a sorted data set.
Analytic Functions
Aggregate functions summarize data, so you get one row per group. But sometimes you need to see the individual rows in the group alongside the totals. To do this you need analytic functions. But that’s not all. Analytic functions enable you to define sliding windows over your rows. So you can compute running totals with ease. This module gives an overview of how to do this.

3. CRUD operations using cx_Oracle and Python for Certification Online Course
Connections and Cursors
In this module, you will learn how to create a connection to Oracle Database. We will also explore some basic functionality of the cursor object in cx_Oracle.
Retrieve Rows (SELECT) with cx_Oracle
It’s important to know how to get data into Oracle Database from your Python programs. But just as critical is getting data back out with SELECT statements. We show you the way with a video and blog post. Then you can get to verify your new-found knowledge with a handful of quizzes.
Update Rows with cx_Oracle
You may work with some tables that are “insert-only” – that is, data is inserted and never changed. But for most tables, you will need to insert rows and then change the values of columns in those rows. For that, you need the UPDATE statement and a driver to execute that statement for you. cx_Oracle to the rescue! So pop some popcorn and watch Blaine’s video. Then catch up on the details in his blog post and prove to the world you’re an expert by answering our quizzes.

4. Analytic SQL for Developers for Certification Online Course
A FREE 6 module boot camp to help you become an expert with Oracle Analytic SQL functions. The course is organized around a series of videos that teach you the concepts and syntax behind analytic functions. Following each video, take a set of quizzes to reinforce what you’ve learned. Got questions? Log them on the AskTOM site with the tag #AnalyticClass in the subject, and Connor McDonald of the answer team will help you out. You can also ask questions about specific quizzes here at the Dev Gym, once you’ve submitted your answers.
Predicates and Partitioning for Certification Online Course
Using analytic functions as a predicate (eg, “Show me the top 5 highest salary earners”) requires care to ensure the results are logically consistent. The Partitioning clause in Analytics (not to be confused with table partitioning) is the means via which analytic expressions can be applied to logical groupings of data within a result set.
Problem Solving with Analytics
Now that the syntax components and function usage have been covered, we move on to applying those skills to solving specific problems using analytic functions.

5. Get Started with PL/SQL Table Functions for Certification Online Course
Table functions are functions that act like tables in a SELECT statement: you can query columns and rows from the array returned by the function! Table functions are a great way to programmatically construct data sets and also play a key role in data warehouses that need to perform multiple transformations of data within a single SQL statement. This class starts with table function fundamentals, then explores streaming table functions, and finishes up with a look at pipelined table functions.

Returning Multiple Columns from a Table Function for Certification Online Course
Suppose you want your table function to return multiple columns, just like most relational tables. Then what do you do? Well, you create an object type, an array of those object types, and construct data as needed to populate that array. Sound complicated? Not really! Watch our video, read a blog post, then finish up with quizzes to drive the points home.
