マイクエリ

SELECT jobs.id as jobID, 
     -- c.name AS Customer,jobs.job_no, 
      invoices.invoice_due_date, 
      jobs.id, 
       ((invoice_items.amount * invoice_items.quantity * invoice_items.exchange_rate)) as Ammount 
FROM invoices 
INNER JOIN `invoice_items` ON invoices.id = invoice_items.invoice_id 
INNER JOIN `jobs`    ON jobs.id = invoices.job_id 


-- INNER JOIN `company` as c ON c.company_id = jobs.company_id -- jobs and company. 


WHERE invoices.type = 'sales' 

-- new conditions 
    AND MONTH(jobs.created_at) = '3' 
    AND YEAR(jobs.created_at) = '2017' 
    AND jobs.status > 0 
    AND jobs.complete_job > 0 
    AND jobs.completed_at IS NOT NULL 

    AND invoice_items.deleted_at IS NULL 
GROUP BY jobs.job_no 
ORDER BY invoices.invoice_due_date DESC
