Hello all,

I have a database:

The database is called "example".
There are two tables called "ticketlines" and "receipts".
In "ticketlines" there are three fields "ticket", "product" and "units".
In "receipts" there are two fields "id" and "datenew".
"ticket" and "id" are the same. They are related.


I need to extract this:
The amount of "units" of "product" sold in the last 24 hours.

So far, my query is this:

SELECT product, units, ticket, id, datenew
FROM example.ticketlines, example.receipts
WHERE timediff(now(), datenew) < '24:00:00';

Which is a terrible failure and returns 1000 rows of data from a database that only has 43 rows.

Help a simpleton out, please!
