Thread: problem with view in 7.3
Hi , I am Hristo Neshev From Bulgaria
In Version 7.2 this statement works :
create view v_impr_check
(

ead_date,
e_no,
e_date,

waste_qty,
rest_qty,
original_used_qty
)
AS
select distinct md_custom_number,
md_custom_date,
md_number ,
md_date ,
sni_sid ,
sni_number ,
snig_ord_number_in,
cdt_part_number,
cdt_description,
snig_quantity,
(select sum(impo_quantity) from impr_out where impo_store_note_in = snig_store_note_in and impo_ord_number_in = snig_ord_number_in),
(select sum(impow_quantity) from impr_out_waste where impow_store_note_in= sni_sid and impow_ord_number_in = snig_ord_number_in),
(select sum(iwnog_quantity) from impr_waste_note_out_goods where iwnog_store_note_in = sni_sid and iwnog_ord_number_in = snig_ord_number_in and iwnog_impr_note_out not in (select impow_iwnog_impr_note_out from impr_out_waste where impow_iwnog_impr_note_out is not null) ),
snig_used_quantity
from
store_note_in join md_header on md_sni_sid = sni_sid
join store_note_in_goods join commodity on (snig_commodity = cdt_sid)
on sni_sid = snig_store_note_in
Where
sni_type_doc = 303;

In 7.3 when i am trying to recreate the view I received the folowing error :
find_expr_references_walker: bogus varno 8
The problem is in subselect statements
