How do I get a result across 2 tables

Question

I have 2 tables. One is called booking and another one is called room. The columns in booking are: RoomID, startdate, enddate, customerId. The columns in room is: RoomID, size.<

Answer 1

Use a basic INNER JOIN to achieve that.

SELECT b.*
FROM booking b INNER JOIN room r USING(RoomID)
WHERE @date_input BETWEEN startdate AND enddate AND size = @size_input;

Change @date_input and @size_input to your real input.

Answer 2

Try this code

SELECT booking.*
FROM booking   JOIN room  USING(RoomID)
WHERE column_name BETWEEN startdate AND enddate AND size = @size_input;
