Hello
As an individual who is new to the field of data science, I am keen to gain insights into the fundamental SQL commands that data scientists should possess knowledge of. I would appreciate your guidance on this matter.

Please understand that, due to the nature of your question, I believe this post is the first of one-two spam punch.

If you are not a spammer or a bot, then don't rely on a single source. Do a search for "SQL Commands for data scientists" and start reading the articles that appear. 😉 The following search links will get you started.

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.

MY SQL command for a data scientist would be to stay away from querying my SQL server and use the models the organization spent cumulative millions on developing.
