Hello All,
I've have a question for you, basically i have to reproduce the same query SQL in QlikSense:
Select
s.shipment_id,
s.request_id,
su.serial_id,
( select max(ru1.request_unit_id)
from request_unit ru1
where ru1.serial_id = su.serial_id
and ru1.created_dttm < su.created_dttm ) last_repaired_unit
from shipment s
, shipment_unit su
where 1 = 1
and s.shipment_id = su.shipment_id
and su.serial_id ='14277PP20385546'
and s.shipment_id='1505885'
result:
shipment_id request_id serial_id last_repaired_unit
1505885 167026 14277PP20385546 2103472
To be clear i have 2 table:
SHIPMENT_UNIT:
shipment_id
serial_id
REQUEST_UNIT
serial_id
request_unit_id
In this method i will have for one serial number more than one request_unit_id and i need only the max value of this filed.
Is possible to do that? thank You Massimiliano
