🚀 *Gen AI Engineer (Production Focused)* The INNER JOIN keyword selects records that have matching values in both tables.
SELECT column_name(s)
FROM table1
INNER JOIN table2
ON table1.column_name = table2.column_name;
The INNER JOIN keyword selects all rows from both tables as long as there is a match between the columns. If there are records in the "Orders" table that do not have matches in "Customers", these orders will not be shown!
CREATE TABLE customers(
