I'm having trouble with my SQL JOIN statements. Can you help me debug them?
Of course! What specific issue are you encountering with your JOIN statements?
I keep getting an empty result set when I use INNER JOIN. What could be wrong?
An empty result set usually means that there are no matching records in the tables you're joining. Can you share your SQL query?
Sure, here it is: SELECT * FROM orders INNER JOIN customers ON orders.customer_id = customers.id
.
Thanks! Check if there are any records in both orders
and customers
tables that match the customer_id
. If one of them is empty or has no matching IDs, you'll get an empty result.
