for loop with file exist function in qlik....

[qliklearnervir]

In our project we having 5 files with name like:

C:\HexaProject\SourceDocuments\Inputfiles\DirectBooking20170101

C:\HexaProject\SourceDocuments\Inputfiles\OnlineBooking20170101

C:\HexaProject\SourceDocuments\Inputfiles\CallBooking20170101

C:\HexaProject\SourceDocuments\Inputfiles\Reference20170101

C:\HexaProject\SourceDocuments\Inputfiles\Cancelled20170101

Every day we need to check these files exist or not …

If exist than we need to load these files as a concatenated solution in 1 table.

but we need to check the availability of all files if any one file is available than table will load .......

[Booking Final]:

Booking_wid,

Booking_Type,

Payment_Method

From “Path”….

Kindly suggest me the way to load these files while using For loop and we need to check each files presence also before doing concatenation……please suggest.

Easiest way:

LET vInputFileDate = Date(Floor(YearStart(Today())), 'YYYYMMDD');

LOAD *

FROM C:\HexaProject\SourceDocuments\Inputfiles\*$(vInputFileDate)

(options and delimiters here);

Note that 20170101 can also be the result of a variable as set above, and that will load whatever file in the folder meets the "*$(vInputFileDate)" criteria.

If you must check whether a single file exist and then load it, then something like this or this would do the job.

[#3]

something like this

for each file in filelist('C:\HexaProject\SourceDocuments\Inputfiles\*.*')

if filetime($(file))>0 then

load

*

from $(file)

;

end if

next
