  • Here are 5 Basic SELECT Statement Queries in SQL so you can begin pulling the information you need out of your database and tables!
    Query demos:
    1) Select ALL from a table: SELECT * FROM table
    2) Select certain columns from a table: SELECT column1, column2, column3 FROM table
    3) Select all the unique or distinct rows in a column from a table. Another way to think of it is "removing duplicates": SELECT DISTINCT column FROM table
    4) Change the displayed name of your columns by adding Aliases: SELECT column1 AS alias1, column2 AS alias 2 FROM table
    5) Add arithmetic in your SELECT statement by using mathematical expressions: SELECT quantity*price AS total_price FROM table

    I might not drop my class because of you. Thank you! You're an incredibly easy to understand teacher. I spent over an hour scouring RUclips before I found your channel. Kinda thrown in the deep end of database concepts class.

    So when you select as alias, is the alias stored indefinitely or does it only run for that query?
