Week 27 – Basic

It’s hard to keep up with new Snowflake features coming out left, right and center. Here’s one that’s created a lot of buzz in the community – EXCLUDE and RENAME. So simple, and yet so much time saved!

Start Up Code
create or replace table frosty_db.challenges.week27 
(
    icecream_id int,
    icecream_flavour varchar(15),
    icecream_manufacturer varchar(50),
    icecream_brand varchar(50),
    icecreambrandowner varchar(50),
    milktype varchar(15),
    region_of_origin varchar(50),
    recomendad_price number,
    wholesale_price number
);

insert into frosty_db.challenges.week27 values
    (1, 'strawberry', 'Jimmy Ice', 'Ice Co.', 'Food Brand Inc.', 'normal', 'Midwest', 7.99, 5),
    (2, 'vanilla', 'Kelly Cream Company', 'Ice Co.', 'Food Brand Inc.', 'dna-modified', 'Northeast', 3.99, 2.5),
    (3, 'chocolate', 'ChoccyCream', 'Ice Co.', 'Food Brand Inc.', 'normal', 'Midwest', 8.99, 5.5);

Take the start up code above, and write a SELECT * query that:

  1. Excludes milktype
  2. Renames icecreambrandowner to ice_cream_brand_owner

This one should only take 5 minutes!

  1. A short challenge indeed, but still a very useful one. Thanks for highlighting the new functionality, I’ve already used it several times to massively simplify scripts on larger column sets!
