What it does
Every time you attempt to combine data from multiple tables in SQL, the results come back wrong: duplicate rows, missing data, or numbers that don't match expectations. The problem typically lies in the JOINs—and when the database has dozens of related tables, getting the query right becomes a puzzle. This prompt constructs SQL queries with multiple tables correctly, explaining each join and ensuring the results make sense. Use it when you need to cross-reference sales data with customers, orders with inventory, or any report involving more than two tables.
