Inner join is a SQL operation used to combine rows from two or more tables based on a related column between them. It's like the Tinder of the database world - only showing matches between tables that have a common interest (key).

How to use it in a sentence

• The new hire was tasked with writing a query to inner join the "customers" and "orders" tables to analyze purchasing behavior, but they spent so long trying to figure out the syntax that the company went bankrupt before they finished.
