Hi All,
I'm working on a Intranet database with a few tables to allow all
the workers from the company to access it.
However, I'm facing a problem with a QUERY. I've did try to use
JOIN but I'm not able to get the results I need...
I have 3 tables (concerning this problem):
Table 'Quotes'
I would like to do a SELECT that would return all the fields in the
'Quotes' table plus the client info and plus the product info but
only if available. If product info is not available I would like to
get a result having all 'Quotes' info and 'Clients' info.
My query is:
SELECT * FROM
From Davor:
Try this:
SELECT * FROM `Quotes` LEFT OUTER JOIN `Products`
ON (`Products`.`QuoteID`=`Quotes`.`QuoteID`)
LEFT OUTER JOIN `Clientes` ON
(`Clientes`.`ClientID`=`Quotes`.`ClientID`)
WHERE `Quotes`.`QuoteID`=6936
