SELECT * means "every column". FROM orders names the table. Together they ask the database for everything it has. Go on:
That's it. You asked, the database answered: five rows, every column. The same sentence works on a table of five rows or five billion.
Now break it on purpose. Change orders to order and run again. Read the error, then fix it. Errors are just the database telling you what it could not find, and getting comfortable with them early is half the battle.
You now know the sentence every data question starts with: SELECT something, FROM a table. It is also the name of this site. The next course teaches you to sharpen that sentence until it answers real business questions.
What did SELECT * FROM orders give you?
Where to go deeper
This was a taste. The real first lessons live in SQL Fundamentals, the free course built for exactly this: one small idea at a time, starting with SELECT and FROM done properly, then filtering rows, sorting, and more. One more short lesson here first: where all of this takes your career.
