FirstSortedValue()

[Volker]

I have two Tables:

Table 1 (Tax):

ID
DateFrom
Percent

Table 2 (Invoice):

InvNr
InvDate
Amount
TaxID

The Problem I have is, that I need the Percent from Table 1 where table1.ID=table2.TaxID and the last Date where table1.DateFrom<=table2.InvDate

In SQL I would describe it as:

select
table1.Percent
from table1, table2
where table1.ID=table2.TaxID and table1.DateFrom<=table2.InvDate
order by table1.DateFrom desc Limit 1

but I have no idea how to say it in QlikView.

You can use IntervalMatch() function. More info here.

Example:

IntervalTable:

LOAD Key, ValidFrom, Team from IntervalTable.xls;

NullAsValue FirstDate,LastDate;

 

Key:

LOAD

Key,

ValidFrom as FirstDate,

date(if(Key=previous(Key),

previous(ValidFrom) - 1)) as LastDate,

Team

RESIDENT IntervalTable order by Key, ValidFrom desc;

 

drop table IntervalTable;

 

Transact:

LOAD Key, Name, Date, Sales from Transact.xls;

 

INNER JOIN intervalmatch (Date,Key) LOAD FirstDate, LastDate, Key RESIDENT Key;
