Meet the SQL Workbench
The workbench is where you try SQL, read results, and fix mistakes.
Every interactive lesson has the same basic workbench: a SQL editor, a Run button, hints, a revealable solution, and a results or error panel.
Errors are part of the workflow. A useful SQL habit is to run a query, read the message, make one small fix, and run it again.
select column_one, column_two
from table_name
limit 5Schema · Garden ShopTable · products9 columns · 24 rows
One row per product, with price, cost, and inventory levels.
Run the starter query to see what happens, then fix it so it shows each product's product name and price for the first5 rows.
- Columns: product_name, price.
- Rows: 5 products.
- The query should run without an error.
