Question

essentially I want to left join 3 tables I have joined 2 tables below

SELECT  * 
FROM    Shop_id i
        LEFT JOIN Shopper s 
           ON i.shopper_id = s.uid
WHERE   i.shopper_comp > 0 AND 
        i.editor_comp = 0
ORDER BY i.sid

I have already successfully joined Shop_id i and Shopper s I want to add Clients c to the mix I thought-

SELECT  * 
FROM    Shop_id i
        LEFT JOIN Shopper s, Clients c 
           ON i.shopper_id = s.uid AND i.cid = c.CID
WHERE   i.shopper_comp > 0 AND 
        i.editor_comp = 0
ORDER BY i.sid

I was wrong – Help please

Answer 1

you need to explicitly specify the keyword LEFT JOIN for the table clients.

SELECT * 
FROM   Shop_id i
       LEFT JOIN Shopper s
          ON i.shopper_id = s.uid 
       LEFT JOIN Clients c 
          ON i.cid = c.CID
WHERE  i.shopper_comp > 0 AND 
       i.editor_comp = 0
ORDER BY i.sid
