Finding Order Lines with only top model and no child items

Question

Hi All,
Can you please help me in finding out the Order lines which are having only top model and no child item and the lines total is zero. I framed a query for this but it takes too long time to retrieve such lines. the query is:
select top_line_id, header_id,flow_status_code ,line_type_id
from (select count(*) lines, top_model_line_id top_line_id, header_id,flow_status_code ,line_type_id
from oe_order_lines_all
where flow_status_code in ('BOOKED','ENTERED')
and line_type_id IN (<line_type_id>))
group by top_model_line_id,header_id,flow_status_code,line_type_id)
where oe_totals_grp.get_order_total (header_id,top_line_id,'ALL')<=0
and lines <=1
order by line_type_id desc;
Can you please help me in this case?
Thanks

Hi,
You can try including the condition top_model_line_id is not null. I think that would make the query faster because it would allow the use of an index. The query would look like:
select top_line_id, header_id,flow_status_code ,line_type_id
from (select count(*) lines, top_model_line_id top_line_id, header_id,flow_status_code ,line_type_id
from oe_order_lines_all
where flow_status_code in ('BOOKED','ENTERED')
and top_model_line_id is not null
and line_type_id IN (<line_type_id>)
group by top_model_line_id,header_id,flow_status_code,line_type_id)
where oe_totals_grp.get_order_total (header_id,top_line_id,'ALL')<=0
and lines <=1
order by line_type_id desc;Hope it helps.
Regards.
