Importing text files or compressed files in QlikView using a batch file - batch-file

Question

I have multiple text files in a folder. I need those files to be imported into QlikView on a daily basis. Is there any way to import those files using batch/command file?
Moreover, can I import compressed files into QlikView?

Answer 1

I am not sure how your load script is set up, but if you wish to refresh your QlikView document, and you don't have QlikView Server, then you can use a batch file as follows:
"<Path To QlikView>\QV.exe" /r "ReportToReload.qvw"
The /r command parameter tells QlikView to open the document, reload it and then save and close the document. However, you must make sure that the QlikView User Preference option "Keep Progress Open after Reload" is not enabled, otherwise the progress dialogue will wait for you to close it after the document has been reloaded.
You can then schedule this batch file to run via Windows' Task Scheduler, or your favourite scheduling tool.
QlikView cannot import compressed files (e.g. Zip/RAR etc.), so you would need to extract these first using a batch script.

Answer 2

You can loop over your directory structure and read the existing files in your load script.
LET vCustCount = NoOfRows('Kunde');
TRACE Anzahl Kunden: $(vCustCount);
FOR i=1 TO $(vCustCount)
LET vNameKunde = FieldValue('name_kunde',$(i));
FOR each vFile in filelist ('$(vNameKunde)/umsatz.qvd')
TRACE $(vFile) hat eine umsatz.qvd;
LOAD ....
FROM [$(vFile)] (qvd);
NEXT vFile
NEXT
In this case I load pre-calculated qvd files but you could do the same with txt, csv ...
And as i_saw_drones mentioned QlikView cannot import compressed files. If you need to read compressed files you can batch operate them with a unzip tool.
You should have a look at
21.1 Loading Data from Files
in the Reference Manual.

Following script checks whether qvd exists or not. If, yes then it update it otherwise create a new qvd
IF NOT isNull(qvdCreateTime('G:\TestQvd\Data.qvd')) THEN
data2:
load * from G:\TestQvd\Data.qvd(qvd);
FOR each vFille in filelist ('G:\Test\*')
LOAD * FROM
[$(vFille)]
(txt, codepage is 1252, explicit labels, delimiter is spaces, msq);
NEXT vFille
ELSE
FOR each vFille in filelist ('G:\Test\*')
data2:
LOAD * FROM
[$(vFille)]
(txt, codepage is 1252, explicit labels, delimiter is spaces, msq);
NEXT vFille
ENDIF
STORE data2 into G:\TestQvd\Data.qvd;
exit Script;
