Extracting a String from a Larger String

[Anonymous]

Ok, I worked on this quite a bit today using the various examples I found in the forums but I still can't get the result I need.

I need to extract the name of the last OU value before 'OU=Enterprise' is encountered. The number of OUs in the string can vary so trying to find the logic to deal with that is killing me.

In the example above, I need my chart dimension to give me 'Food', 'Food' and 'Deskless Workers'.

A quick and not-so-dirty solution:

AD:
LOAD * INLINE [
ActiveDirectoryString
'CN=Alpine\,Patricia,OU=Users,OU=123,OU=Cladwell,OU=Food,OU=Enterprise,DC=na,DC=simplot,DC=com'
'CN=Anderson\,Beverly G,OU=Plant Users,OU=Cladwell,OU=Food,OU=Enterprise,DC=na,DC=simplot,DC=com'
'CN=Anderson\,Misti,OU=A-H,OU=Deskless Workers,OU=Enterprise,DC=na,DC=simplot,DC=com'
];
ADNew:
LOAD if(x1='OU=Enterprise', replace(previous(x1), 'OU=', '')) as Dimension;
LOAD subfield(ActiveDirectoryString, ',') as x1
RESIDENT AD;
DROP Table AD;

I am sure there are many other fancier ways to do the same.

Hope this helps.

You can either put this on Dimension expression or load script. Will only work if the last instance of OU=<Value> is beside OU=Enterprise. I hope this helps.

TextBetween(<Your String Column>, ',OU=', ',OU=Enterprise',substringcount(<Your String Column>,',OU=')-1)

Thanks pinongs, that was perfect. As with everything in QlikView, the solution was far easier than I thought it would be.
