Shouldn't affect performance, but another way to write this which you
may find more readable is to list your join conditions with the joins
rather

Hey All,
I have a query I'm trying to speed up, and I was hoping someone could
help me. I have a three tables a and b hold data, and c just references
between a and b:
create table a (
a_id int,
x int
);
create table b (
b_id int,
x int
);
create table c (
a_id int,
b_id int

OK, that works great, but I was told that I should avoid sub-selects when
possible for performance reasons. Also, I used so much mental energy trying
to find a solution that would do either task using a join that I would be
very curious if anyone had a solution.

Hi all.
I have a table with members and a table with payments. Each payment is
related to a member by memberID and each payment has (among other things) a
year paid.
I can create a join to find a list of members who have paid for a given year

For the SQL gurus, a query where I'm not getting

There are two tables:
