Text Finder: Search a Messy Table
Build the search and filter layer that finds anything in a table full of inconsistent text, the query behind every search box.
What you'll be able to build
Build the search and filter layer that finds anything in a table full of inconsistent text, the query behind every search box. Along the way you pick up real, transferable SQL skills, not just this one project:
- LIKE and wildcard patterns (% and _)
- GLOB and case-sensitive matching
- CASE expressions to tag and bucket rows
- COALESCE and IS NULL for missing text
- combining filters with AND/OR/NOT
- ordering results by relevance proxies

How the lessons actually work
Every lesson has you predict what a piece of SQL code will output before you run it, then run it for real in your browser and fix what you got wrong. Each module ends in a challenge gate with hidden tests, so you can't advance until your code actually works. The course closes with a capstone that assembles everything into Text Finder, and a runnable proof page tied to your own code.
