Hi,
I have an app that parses a directory for files with a specific ending (xls in this instance) and matching a specific name.
- The issue is, in this one directory, those files (they are generated and saved there automatically) are saved with a timestamp,
so there are hundreds of files there.
- The files have a few different names
- FA_TAR or FA_TAS
- FA_TAR_FC or FA_TAS_FC
- FA_TAR_RW or FA_TAS_RW
=> There are six different filenames possible.
I have no problem with the latter four for they are unique of course.
<=> The first two, FA_TAR and FA_TAS, are problematic insofar as when I make a searchmask to fit those, I use the * (because of the timestamp) and so two of the other four also match that (when the filemask is >> FA_TAR*.xls <<, then FA_TAR_FC*.xls and FA_TAR_RW*.xls also match)
Currently I have a LOAD with a PRECEDING LOAD. It looks like this (the variables are all correct; p4 is the filename I look for and p5 is a specifier like >> (biff, no labels) <<)
>> FOR EACH v_file in FileList('$(v_filemask)');
Temp:
FIRST 1 LOAD
*
WHERE Aktuell_jn = 1
AND Subfield(Subfield(Dateiname, '.', 1), chr(32), 1) = '$(p4)'
// AND KEEPCHAR(Subfield(Dateiname, '.', 1), 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZÄÖÜ456780_') = '$(p4)'
;
FIRST 1 LOAD
Filename() as Dateiname,
FileTime() as Änderungszeit,
IF(Date(Floor(num(FileTime())), 'DD.MM.YYYY') = DATE(Today(), 'DD.MM.YYYY'), 1, 0) as Aktuell_jn
FROM
$(v_file)
$(p5)
;
NEXT
This construct works fine - but when it comes to the searchmask >> FA_TAS*.xls << or >> FA_TAR*.xls << - hundreds of files are parsed and then discarded.
For some reason, that construct I have for the field >> Aktuell_jn << does not work if I use it in a WHERE clause in the main load - then I could do without the PRECEDING LOAD and just disregard all those other files. But, well, it doesn't work so I have to use the PRECEDING LOAD.
Can anyone suggest something here?
Thanks a lot!
Best regards,
