Save results of formulas in Qlik

[pascaldijkshoor]

Hello,

I am working with a dataset that overwrites data. This means everyday when I reload the data, i get different results and I can't see the results of the day before anymore. So the results of my formula's only show the current situation. Is it possible to save these results, so i can create a timeline of results.

For example, I have a formula that calculates the occupancy. Is it possible to create a formula that saves the occupancy daily, so i get a timeline with the occupancy per day?

Hi Pascal,

You can store these information in file.

You can create a file in load script, read it, append a new line and store the new file.

May be you can save the data into QVD's on daily basis:

ABC:

LOAD *;

SQL

Select * from ABC where Date = 'DD/MM/YYYY';

LET vDay = Date(Today(),'DD/MM/YYYY'');

STORE ABC into D:\$(vDay).qvd;

********************* After storing data into QVDs, call them into application using below script ********************

for each vFile in FileList('.\Data\*.qvd')

     let vFileName = mid(vFile, index(vFile, '\', -1) + 1, 99);

     QvdFields:

     LOAD

          1                      as FieldCount,

          '$(vFileName)'         as [File Name],

          FieldName              as [Field Name],

          BitOffset              as [Bit Offset],

          BitWidth               as [Bit Width],

          Bias                   as [Bias],

          NoOfSymbols            as [No Of Symbols],

          [NumberFormat/Type]    as Type,

          [NumberFormat/nDec]    as Dec,

          [NumberFormat/UseThou] as UseThou

     FROM [$(vFile)] (XmlSimple, Table is [QvdTableHeader/Fields/QvdFieldHeader]);

next

if you also want to add in some header information, such as number of rows, you can add another statement within the loop to pull in those values:

     QvdTableHeader:

     LOAD

          1                      as QVDCount,

          '$(vFileName)'         as [File Name],

          QvBuildNo              as [QV Build No],

          CreatorDoc             as [QVD Creator],

          CreateUtcTime          as [Time Created],

          SourceFileSize         as [Source File Size],

          TableName              as [Table Name],

          RecordByteSize         as [Record Byte Size],

          NoOfRecords            as [Number Of Records]

     FROM [$(vFile)] (XmlSimple, Table is [QvdTableHeader]);
