How can I get all products from customers1 and customers2 include their customer names?

customer1 table
cid name1
1   john
2   joe

customer2 table
cid name2
p1  sandy
p2  linda

product table
pid cid pname
1   1   phone
2   2   pencil
3   p1  pen
4   p2  paper

Result should be like this

pid  cid  pname  name1 name2
1    1    phone  john  NULL
2    2    pencil joe   NULL
3    p1   pen    NULL  sandy
4    p2   paper  NULL  linda

SELECT p.pid, p.cid, p.pname, c1.name1, c2.name2
FROM product p
LEFT JOIN customer1 c1 ON p.cid = c1.cid
LEFT JOIN customer2 c2 ON p.cid = c2.cid

SELECT pid, cid, pname, name1, name2 
FROM customer1 c1, product p 
WHERE p.cid=c1.cid 
UNION SELECT pid, cid, pname, name1, name2 
FROM customer2 c2, product p 
WHERE p.cid=c2.cid;

  • name2 is an unknown column in the first half of that union (and name1 in the second half) – Rowland Shaw Sep 12 '09 at 20:20
  • There's no name2 column in either CUSTOMER table - you need to rearrange the customer name columns, swapping for null to match the desired output. Once that's done, you do provide an alternative to the LEFT JOINs most of us came up with. – OMG Ponies Sep 12 '09 at 20:20
  • @rexem there is in the customer2 table – Rowland Shaw Sep 12 '09 at 20:21

SELECT `product`.*, `customer1`.`name1`, `customer2`.`name2`
FROM `product`
LEFT JOIN `customer1` ON `product`.`cid` = `customer1`.`cid`
LEFT JOIN `customer2` ON `product`.`cid` = `customer2`.`cid`
