What is an INNER JOIN?

< 1 min read

An INNER JOIN returns only the records that have matching values in both tables.
It excludes rows where the join condition does not match.
This is useful when only valid, related data is needed.
In my project, we used INNER JOIN between orders and customers.
Only orders with a valid customer record were extracted.
This helped maintain data accuracy in reports.
INNER JOIN is the most commonly used join in analytics queries.
