My coding style is to explicity define inner/left joins. That said, I've increasingly run into code like this which is effectively an inner join:
Proc SQL;
Create table abc as
select *
from
table1 A,
table2 B
where
a.key = b.key and a.id = b.id;
quit;
I recently ran into this:
Proc SQL;
Create table abc as
select *
from
table1 A,
table2 B
where
a.key = b.key (+) and a.id = b.id;
quit;
Can someone tell me what the (+) is doing?
"Can someone tell me what the (+) is doing?"
That's Oracle syntax for implicit left or right joins.
"Can someone tell me what the (+) is doing?"
That's Oracle syntax for implicit left or right joins.
