MySQL select statement missing some fields - mysql

Question

I have following statement that is used to select some fields from MySQL DB
select finance_budget_issue.budget_date, SUM(finance_budget_issue.amount) AS amount, finance_vote.office_id as vote_office_id, finance_office.office_head as head,
finance_office.office_name AS office_name,
finance_budget.ref_no, finance_budget_issue.view_status, tbl_signature.office_head as sign_office_head, tbl_signature.name AS name,
tbl_signature.post AS post, tbl_signature.sign_id
from finance_budget_issue
inner join finance_budget on finance_budget.budget_id=finance_budget_issue.budget_id
left join finance_vote on finance_budget_issue.vote_id=finance_vote.vote_id
left join finance_vote_description on finance_vote.description=finance_vote_description.vote_description_id
left join finance_office on finance_budget_issue.office=finance_office.office_id
left join tbl_signature on finance_office.office_id=tbl_signature.office_id
The statement is working fine, but didn't outs the following fields
tbl_signature.office_head as sign_office_head,
tbl_signature.name AS name,
tbl_signature.post AS post
What may be going wrong ? I think that I used incorrect Joins. Can anyone help ?
Tables as follows :

Answer 1

This is easier to read:
SELECT i.budget_date
, SUM(i.amount) amount
, v.office_id vote_office_id
, o.office_head head
, o.office_name
, b.ref_no
, i.view_status
, s.office_head sign_office_head
, s.name
, s.post
, s.sign_id
FROM finance_budget_issue i
JOIN finance_budget b
ON b.budget_id = i.budget_id
LEFT
JOIN finance_vote v
ON v.vote_id = i.vote_id
LEFT
JOIN finance_vote_description d
ON d.vote_description_id = v.description
LEFT
JOIN finance_office o
ON i.office = o.office_id
LEFT
JOIN tbl_signature s
ON s.office_id = o.office_id
You have an aggregate function (and non-aggregated columns) but no GROUP BY clause; that's not going to work. You have a LEFT JOINed table from which you select no columns; that's pointless.
