Guru99: PL/SQL 101 Completely Free!

Hey all!
Just passing by today to share something I found really inetresting, and the best: it’s all free!
Do you know Guru99?

It’s a preety nice repository with lots of free tutorials and guides for PLSQL, SQL and several other languages, plus some other IT-related knowledge, like Big Data, PMP and etc.

It’s not rare to have people asking me “How to Start learning SQL” or saying “All material (including grepora :D) is too much specific, we don’t have good general documentation”.
Even Oracle having a pretty nice documentation on the products and features, general concepts are usually forgotten. Aaaaand, now I have something to link on those cases! 😀

Having a look on Guru99, First I found this guide PL/SQL First Program: Hello World, including detailed steps on:
– How to access SQL* Plus
– Connecting to Database
– How to write a simple program using PL/SQL
– Declaring and usage of variables in program
– Commenting Codes

Then found an entire category PL/SQL Tutorials. Talking to Alex (Editor), seems over 120 hours were spent on it. And they were well spent, the material is really very easy to read and understand. Chapters on this Course are:
1. Introduction to PL/SQL
2. Blocks in PL/SQL
3. PL SQL First Program: Hello World
