Question

I have 2 tables I need to query with similar contents but differing field names.

I’m wanting to merge the following 2 queries into 1 so that I have 1 set of results.

The 2 queries are:

  SELECT 
    bookings.booking_name,
    bookings.booking_email,
    bookings.booking_mobile
  FROM 
    bookings   
  WHERE 
  ( bookings.booking_email LIKE "%' . $_POST['val'] . '%"
  OR 
    bookings.booking_name LIKE "%' . $_POST['val'] . '%"
  OR 
    bookings.booking_mobile LIKE "%' . $_POST['val'] . '%"
  )


SELECT 
    purchases.customer_name,
    purchases.customer_email,
    purchases.customer_phone
FROM 
 handbags
WHERE   
  ( purchases.customer_email LIKE "%' . $_POST['val'] . '%"
  OR 
    purchases.customer_name LIKE "%' . $_POST['val'] . '%"
  OR 
    purchases.customer_phone LIKE "%' . $_POST['val'] . '%"
  )

How is this sort of thing accomplished so that in my result customer_email and booking_email can be accessed simply by ’email’.

Answer 1

Combine the two queries with the UNION operator, and give the columns matching names.

(SELECT 
  bookings.booking_name AS name,
  bookings.booking_email AS email,
  bookings.booking_mobile AS phone
FROM 
  bookings   
WHERE 
( bookings.booking_email LIKE "%' . $_POST['val'] . '%"
  OR 
  bookings.booking_name LIKE "%' . $_POST['val'] . '%"
  OR 
  bookings.booking_mobile LIKE "%' . $_POST['val'] . '%"
))
UNION
(
SELECT 
  purchases.customer_name AS name,
  purchases.customer_email AS email,
  purchases.customer_phone AS phone
FROM 
 handbags
WHERE   
( purchases.customer_email LIKE "%' . $_POST['val'] . '%"
  OR 
  purchases.customer_name LIKE "%' . $_POST['val'] . '%"
  OR 
  purchases.customer_phone LIKE "%' . $_POST['val'] . '%"
));
