Daily extraction

mahitham — Wed, 25 Nov 2020 16:16:04 GMT

Hi Experts,

Can any one please help me to extract date wise qvds and to store qvd with QLIK_DD/MM/YYYY Format.

I have prepared sample excel file for explaining the requirement.

My date field is like DDMMYY Format in database.

The attached excel file contains three dates but in the real environment one qvd contains last 6 months data from this qvd need to extract one qvd for one date and need to store the qvd with date extension.

Please help me to do with for loop. Please find the attached excel file.

expected output:

1. QLIK_09/04/2018.qvd

2. QLIK_10/04/2018.qvd

Thanks in advance

first you need to get the min and max value of the dates. for example by sorting it and then use peek to get the first(0) and last(-1) value. then do a for min to max

within that for loop resident where date = the for counter. and store into qvd with the counter ar the end of the name.

Hi,

Sadly the format you want for the date is not supported when saving qvd so maybe you can think of a different output like 09_04_2018 and your system date is a bit tricky but i managed to do it.

Don't forget to put your own paths!

Regards,

Andrew

Hi Andrei,

Could you please share the script or qliksense qvf file.

I don't have Qlikview license.

Thanks in advance.

ok.

let vPath='.\loop\';

Temp1:

Load *,

MakeDate(Year,Month,Day) as DateNew;

LOAD Date,

'20'&right (Date,2) as Year,

if(len(Date)<6,mid( Date,2,2 ),mid( Date,3,2 )) as Month,

if(len(Date)<6,left(Date,1),left(Date,2)) as Day

FROM

[.\QLIK.xlsx]

(ooxml, embedded labels, table is [Daily extraction]);

Extractions:

LOAD Distinct Date , DateNew

Resident Temp1;

Drop table Temp1;

let vNoOfRows= NoOfRows('Extractions');

for i=0 to $(vNoOfRows)-1

let vDBDate=peek('Date',i,'Extractions');

let vNewDate=text(peek('DateNew',i,'Extractions'));

Temp2:

NoConcatenate

LOAD Client,

FROM

[.\loop\QLIK.xlsx]

(ooxml, embedded labels, table is [Daily extraction])

where Date=$(vDBDate);

let vQVD= vPath & 'QLIK_'& vDBDate;

STORE Temp2 into [$(vQVD).qvd] (qvd);

drop Table Temp2;

next i;

drop table Temp1;
