I have a select statement that goes as follows:

SELECT * FROM product prod, prod_alias pa, category cat, company co
WHERE prod.catid = cat.catid
AND prod.coid = co.coid
AND prod.prodid = pa.prodid;

If possible, I want to change the statement so that I get output regardless of whether there's a match between prod.prodid and pa.prodid. IOW, if there's a match between prod.prodid and pa.prodid, I want the output from both the product table and the prod_alias table. if there's no match, I still want the output from product table. Can I do this in one select statement?

Thanks,

Don
