Very good for PL/SQL Developers and new APEX Developers. Thank you very much.

This pulled together so many bits and pieces of web knowledge gained randomly over the years. Thank you!

I've only had to use JavaScript occasionally, and usually copy/paste examples from the web, so it was quite helpful to see a side-by-side syntax comparison between PL/SQL and JavaScript. Now I know why some of my guesses on syntax did not work! Same thing with Developer Tools and the console; in terms of what / how you can invoke immediate commands. No longer will I usually panic when I type in certain commands in the console and see "undefined" -- sometimes that should be expected, such as when defining a variable.

Greetings. I realize this video is a bit old now, but the exercises referenced in the link later in the video do not seem to be available on github currently. Are they available anywhere else? Thanks, and thanks for making these videos.

Thanks, Shakeep for this valuable tutorial, I have a question here, at 27:40 you say "procedure never return a value". But we can use an OUT parameter to return a value from procedure. can you explain that please?

[@dinudinesh5297]

Yeah you are right! Procedure may or may not return a value.

[@MarkStewart1337]

@@dinudinesh5297 But actually, it is sending the value back via a parameter, not a single return value.. IE: a procedure invocation never returns a single value; it might send back one or more values via OUT parameters.
