syntax error in PROC SQL

Hi everybody.

Where is the syntax error?

PROC SQL;

SELECT p.*,c.unicost,s.quantity

FROM product,cost,sales

WHERE product.item = cost.item AND product.item = sales.item;

QUIT;

Best regards, Cons.

You use alias in your select clause (p/c/s) but don't assign any aliases to your tables.

PS it's usually more efficient to specify join type and use ON rather than WHERE.

@Reeza, I agree with your diagnostic of OP's syntax error.

However, a simple WHERE clause is just as efficient as the ON clause of an INNER JOIN. One is simply translated into the other, when possible. I do prefer the JOIN syntax because it is more explicit, but it isn't more efficient.
