restart autonumber qlik sense

joeybird — Mon, 14 Nov 2016 15:19:28 GMT

each CustomerID has number of OrderID

This order id can look like this x11533322

I wish to autonumber these, but restart the autonumber per customer

I have tried to use in the load

AutoNumber( CustomerID & '|' & OrderID ) as ID

AutoNumber( OrderID ) as ID

I wish for the output to show as

CustomerID - ID

A 1

A 2

A 3

A 4

B 1

B 2

B 3

Please help

Hi Joanna,

maybe

Autonumber(RowNo(),CustomerID) as ID

Regards,

Antonio

Or even this:

AutoNumber(RecNo(), CustomerID) as ID

While I have heard that AutoNumber is sometime slow for huge databases, so you can also use Peek/Previous

If(CustomerID = Previous(CustomerID), RangeSum(Peek('ID'), 1), 1) as ID

But make sure to order your data if it is not already ordered by CustomerID

Hi,

I have similar issue but I need to autonumber on multiple columns, but the autonumber gives same output number if the value exists in other column.

In below, if you see for value "200" the autonumber is 3 and it is assigned wherever I have 200 across the columns. Let me know if I can use any other function or how I can reset the autonumber counter back to 1.

ID a1 a1_Autonum n1 ni_autonum

1 100 1 200 3

2 200 3 150 9

base:

load * Inline [

id, a1, n1, r1

1,100, 200, 300

2,200, 150, 240

3,250, 101, 750

4,600, 150, 225

5,1000, 845, 990

6,101, 1234, 8954

7,200, 345, 675

8,600, 750, 101

9,550, 350, 605

10,500, 185, 230

];

let c = NoOfRows('base');

test1:

load *,AutoNumber(a1) as a1rnk, $(c) as cnt

resident base

order by a1;

test:

load *,'' as samplecolumn resident test1;

drop table test1;

test2:

load AutoNumber(n1) as n1rnk, id, 'test2' as test2

resident base

order by n1;

left join (test)

load n1rnk, id resident test2;

drop table test2;

drop table base;

exit script;
