Dynamic split field into columns in script

Hi there,

I am looking for help on the following issue.

I have a table with many columns which contain multiple-value comma-separated values. The number of comma separated values varies.

  • Fields are as follows
    Project ID
    Project Name
    Project Resources (contain multiple entries)
    Countries covered (contain multiple entries)

I've searched and found entries on subfields, cross table and peek etc, but as I am a newbie, cannot seem to make this work for my data.

Please assist. The sample table is below.

My initial thought is to do the below (but I have no idea how to do this in Qlikview!)

1) Split 'Project Resources' and 'Countries covered' into columns (challenge - variable number of entries - in the full data you can have up to 50 countries covered).

2) Some sort of cross-table, creating a row for each column (challenge - several columns with multiple comma separated values. Might create 'untrue' relationships between the individual values once split).

3) My solution for 2 above is to use the 'Project Resources' and 'Countries covered' as variables.

So, for the below list, for record PPM01 I would expect

   

Project IDProject NameVariableValue
PPM01Project 1Project ResourceTimothy
PPM01Project 1Project ResourceJerry
PPM01Project 1Project ResourceJames
PPM01Project 1Countries coveredThailand
PPM01Project 1Countries coveredMauritania
PPM01Project 1Countries coveredIran
PPM01Project 1Countries coveredCroatia

And finally, I need Project Resource, Countries covered and Project Name to be separate list boxes/ selections on the sheet.

I hope I can find help on here, much anticipating your responses!

Hi,

Try this code:

FACTS:

LOAD [Project ID]        AS [FACT Project ID],

     [Project Name]      AS [FACT Project Name],

     [Project Resources] AS [FACT Project Resources],

     [Countries covered] AS [FACT Countries covered]

FROM .\FACTS.xlsx (ooxml, embedded labels, table is FACTS);

PROJECTS:

LOAD DISTINCT [FACT Project ID]   AS [Project ID],

              [FACT Project Name] AS [Project Name]

RESIDENT      FACTS;

RESOURCES:

LOAD DISTINCT [FACT Project ID]                       AS [Project ID],

              SubField([FACT Project Resources], ',') AS Resource

RESIDENT FACTS;

COUNTRIES:

LOAD DISTINCT [FACT Project ID]                       AS [Project ID],

              SubField([FACT Countries covered], ',') AS Country

RESIDENT FACTS;

This is the result:

27-01-2017 15-45-42.png

And this is the model:

27-01-2017 15-46-50.png

I attach the QVW and excel files of the sample. I hope it serves to you...

Regards,

H

I think subfield() would be the best choice to create separate dimension-tables with something like this:

IDtoCountry:

load [Project ID], subfield(Country, ',') as Country from Source;

Without the third parameter within subfield() in a load it will run like a loop and create for each item a record and also duplicate each other field-values in those records. Without any measure-field within your source-table you could do the subfield() there but I believe a split into several associated tables will be more suitable.

Hi,

Try code like this

LOAD [Project ID],

     [Project Name],

     SubField([Project Resources], ',') as ProjectResources,

     SubField([Countries covered], ',') as CountriesCovered    

FROM

(Your path to the data)

While IterNo() < substringcount([Project Resources] , ',') + 1 Or IterNo() < Substringcount([Countries covered], ',') + 1;

Regards,

Andrey

Something like this perhaps.

load

[Project ID],

[Project Name],

'Project Resources' as Variable,

SubField([Project Resources], ',') as Value

(YourTable)

;


concatenate


load

[Project ID],

[Project Name],

'Countries Covered' as Variable,

SubField([Countries Covered], ',') as Value

(YourTable)

;

Very useful - thanks!

for my task there more situable form of your script

FACTS:

LOAD [Project ID]        AS [FACT Project ID],

    [Project Name]      AS [FACT Project Name],

    [Project Resources] AS [FACT Project Resources],

    [Countries covered] AS [FACT Countries covered]

FROM .\FACTS.xlsx (ooxml, embedded labels, table is FACTS);

PROJECTS:

LOAD DISTINCT [FACT Project ID] , // AS [Project ID],

              [FACT Project Name] AS [Project Name]

RESIDENT      FACTS;

RESOURCES:

LOAD DISTINCT [FACT Project ID]  ,  //                  AS [Project ID],

              SubField([FACT Project Resources], ',') AS Resource

RESIDENT FACTS;

COUNTRIES:

LOAD DISTINCT [FACT Project ID]   ,   //                AS [Project ID],

              SubField([FACT Countries covered], ',') AS Country

RESIDENT FACTS;
