activity_ref.ref_no = activity_plan.ref_no ) AS test_audited
FROM 
activity_plan
inner join user on activity_plan.sales_officer=user.username
INNER JOIN activity_liquid ON activity_plan.aplan_no = activity_liquid.aplan_no
where activity_plan.date between '$date1' and '$date2' and user.branch='no' and     
user.position='Consultant' and activity_plan.validate_1st_status!='pending'  order by     
activity_plan.sales_officer asc,activity_plan.aplan_no asc
