Find Substring, and link to another field

Tue, 26 May 2015 17:54:52 GMT

Hello,

I'm sorry if this is confusing, but it's a bit difficult to phrase. I am looking to search within a field, and if a match is found, return another field from the substring. Below are a fewexamples. The values I'm searching in are not standardized, meaning not the same format with underscores or something similar.

DataSet:

Territory	Coast???
Sales_NorthEast_123	from MatchTable
Manager_xyz_West_012	from MatchTable
Manager_Growth_Northeast_123	from MatchTable

MatchTable:

if Territory contains...	then Coast is...
Northeast	Atlantic
West	Pacific

Final Dataset (Coast is the field I'm looking for)

Territory	Coast
Sales_NorthEast_123	Atlantic
Manager_xyz_West_012	Pacific
Manager_Growth_Northeast_123	Atlantic

Does this make sense? Thanks for any help!

EDIT - I should have mentioned that there are many records to match from, and I don't want to hardcode the cross-ref as this dashboard will be used for many years and would like it to be able to handle new organizations.

Thanks for your feedback thus far. Much appreciated.

Try this:

Mapping:

Mapping

LOAD Upper([if Territory contains...]) as [if Territory contains...],

[then Coast is...] as [then Coast is...]

FROM

[https://community.qlik.com/thread/165611]

(html, codepage is 1252, embedded labels, table is @2);

Table:

LOAD Territory,

ApplyMap('Mapping', Upper(SubField(Territory, '_', -2))) as Coast

FROM

[https://community.qlik.com/thread/165611]

(html, codepage is 1252, embedded labels, table is @1);

Hello, If your Match table is too small and table is static, you can use Wildmatch in IF cond like below.

IF(WildMatch(Territory,'*northeast* , '*west*'), Pick( WildMatch(Territory,'*northeast* , '*west*') ,'Atlantic','Pacific') , 'NA' )

If your Match table is too much the values are changing with short period, then do the cross join & search against each values like below:

DataSet:

LOAD distinct

Territory

From Dataset;

Join

Load

Match_Territory,

Coast

From MatchTable;

Final:

LOAD

Territory ,

Coast

Resident DataSet

Where Substringcount( Upper(Territory) , Upper(Match_Territory))

;

Maybe like this:

MatchTable:

LOAD * INLINE [

F1,F2

Northeast, Atlantic

West, Pacific

];

Map1:

MAPPING LOAD F1, '<'&F2&'>' as F2 Resident MatchTable;

Map2:

Mapping LOAD Upper(F1) as F1, '<'&F2&'>' as F2 Resident MatchTable;

DataSet:

LOAD Territory,

Textbetween(MapSubString('Map1',Territory),'<','>') as Result,

Textbetween(MapSubString('Map2',UPPER(Territory)),'<','>') as ResultCaseInsensitive

INLINE [

Territory

Sales_NorthEast_123

Manager_xyz_West_012

Manager_Growth_Northeast_123

];

Showing a case sensitive or insensitve match. You can replace '<' and '>' with any characters that are not part of your territory text values.

I had almost exactly the same, apart from the case insensitive bit ... So not sure if this will still help, but my example attached

That's beautiful! Need to read up a bit on the MapSubString, but it works like a charm.

Thank you.
