Splitting a data column into 2 columns during import

Hi there!

I would like to ask how I can approach the following:

I have a dataset containing the following:

Product Information

ProductID | Price| Quantity | Expiry

A001        | $50   | 10          | Dec-19

A002        | $40   | 15          | Dec-19

A003        | $30   | 15          | Dec-18

B005        | $35   | 20          | Dec-18

B006        | $45   | 20          | Dec-19


Those productID starting with 'A' are old productIDs and 'B' are new productIDs.


I have another dataset that contains the information to link the old and new ProductIDs.


ProductID dataset

ProductIDold | ProductIDnew

A001             | B001

A002             | B002

A003             | B003


ProductIDs that cannot be found in the table will be taken as is.


When importing into Qliksense, I would like to seperate the new and the old productIDs to form the following table.

ProductIDold |ProductIDnew | Price| Quantity | Expiry

A001             | B001             | $50   | 10          | Dec-19

A002             | B002             | $40   | 15          | Dec-19

A003             | B003             | $30   | 15          | Dec-18

-                    | B005             | $35   | 20          | Dec-18

-                    | B006             | $45   | 20          | Dec-19


So to summarize what needs to be performed:

1) Seperate the ProductID column to ProductIDold and ProductIDnew columns when importing. The other 3 columns will be imported accordingly(Price,Quantity,Expiry).

2) Add the ProductIDnew if there is a ProductIDold using the ProductID dataset


I've tried the following for part 1) but didn't seem to work.

load

     if(wildmatch(productID,'A'),productID) as ProductIDold,

     if(wildmatch(productID,'B'),productID) as ProductIDnew,

     Price,

     Quantity,

     Expiry

  Thanks in advance!

Re: Splitting a data column into 2 columns during import

Hi,

Can you try using ApplyMap:

Product_Map:

Mapping LOAD * Inline

[

ProductIDold,ProductIDnew

A001,B001

A002,B002

A003,B003

]

;

Product_Information:

LOAD *,

if(WildMatch(ProductID,'A*'),ProductID) as ProductIDold,

ApplyMap('Product_Map',ProductID) as ProductIDnew

Inline[

ProductID,Price, Quantity,Expiry

A001,$50  ,10  ,Dec-19

A002,$40  ,15  ,Dec-19

A003,$30  ,15  ,Dec-18

B005,$35  ,20  ,Dec-18

B006,$45  ,20  ,Dec-19

]

;

DROP Field ProductID;

A001             | B001

A002             | B002

A003             | B003

] (delimiter is |);

load *,ApplyMap('map1',ProductID,ProductID) as ProductIDnew,PICK(WildMatch(ProductID,'A*'),ProductID) AS ProductIDold;

load * inline [

ProductID | Price| Quantity | Expiry

A001        | $50   | 10          | Dec-19

A002        | $40   | 15          | Dec-19

A003        | $30   | 15          | Dec-18

B005        | $35   | 20          | Dec-18
