Hi There
I would like to create a field with random numbers within a table ranging from 1- 10
I know the Autonum funtion doesnt work like this, im using it to display what i require...
Load
Transactions:
[Sales Value],
[Sales Quantity],
[Agent Name],
Autonum(10) as [Client Code]
Regards,
rand returns numbers from 0 to 1 so left(rand()*10,1) gives you the result
use function rand() and multiply the result by 10:
load
...
rand()*10 as myRandom
resident
....
how would i limit it between 1 and 10 though?
rand returns numbers from 0 to 1 so left(rand()*10,1) gives you the result
RAND()*9+1 as NUM2
Transactions:
LOAD
[Sales Value],
[Sales Quantity],
[Agent Name],
Ceil(rand()*11) as [Client Code]
FROM yoursource;
For a better probability distribution (normal distribution) I recommend using:
=ceil(norminv(rand(), mean, stdev))
In your example e.g.
=ceil(norminv(rand(),5,3))
Thank you this is great
Hi,
Which version of QlikView did you test the code on, that you marked as correct?
I only get 0 to 9.
Possibly a bug?
thanks
regards
Marco
According to the QV Reference Manual v11 rand() returns a random number between 0 and 1, very possibly excluding 0 and 1.
