Create and Test a Zero-Copy Clone

Before making schema changes to the user_registrations table, Snowy Peak's data team wants an instant backup - one that costs nothing to create and shares underlying storage with the original until the two diverge. You'll create a zero-copy clone, confirm it matches the original, then verify that changes to the clone don't affect the source table.

Use the table's full path in your FROM clause. Get it from the left panel: Databases tab → expand your COURSE_… database → select the table → Copy name.
