Using SQL variables with INNER JOINS - mysql

Question

Im trying to use a variable to count the number of rows i have for a specific id, if i use it without inner joins it works perfectly, otherwise no, here is the section without joins
select
cd.basis_point bpt,
cd.created,
#version:=#version+1 version
from tbl_class_det cd, (select #version:=1) v
where (cd.class_uuid='{$row['uuid']}')
and (cd.created>(
select
created
from tbl_class_det
where (class_uuid=cd.class_uuid)
order by created asc
limit 1
))
order by cd.created asc
the section with joins that gives an error:
select c.name,
fd.value bpt,
fd.created,
#version:=#version+1 version
from tbl_fee_det fd, (select #version:=1) v
INNER JOIN tbl_fee f ON f.uuid = fd.fee_uuid
INNER JOIN tbl_class c ON c.uuid = f.class_uuid
where (fd.created>(
select
created
from tbl_class_det
where (fee_uuid=f.uuid)
order by created asc
limit 1
))
order by fd.created asc;

You are using a combination of explicit and implicit joins. You should not mix the JOIN syntax with the comma syntax. If you need to you this then use a subquery similar to this:
select name,
value bpt,
created,
#version:=#version+1 version
from
(
select c.name,
fd.value,
fd.created,
f.uuid
FROM tbl_fee_det fd
INNER JOIN tbl_fee f
ON f.uuid = fd.fee_uuid
INNER JOIN tbl_class c
ON c.uuid = f.class_uuid
) f, (select #version:=1) v
where (created>(select created
from tbl_class_det
where (fee_uuid=f.uuid)
order by created asc
limit 1))
order by created asc;
