Script help

[amit_saini]

Hi Folks,

I'm having one table called "STICHPROBE" , so normally we are running script below for QVD generator to load data every 2 hours from Database.

Suppose script started running every Monday than Tuesday...Wed...Thus... But on Friday What I'm looking is to load data once again from Monday . So on every Friday's of the Month we gonna load data once again from Monday.

So could u please help how this can be handled by using below script:

********************************************Script Start***********************************************************

LET vStartDate = date(makedate(2015,1), 'DD.MM.YYYY hh:mm:ss');

Set vQVD = 'D:\qvprod\QV_QVD';

Let vQVDCurrentYear = 'D:\qvprod\QV_QVD\'& year(today());

$(Include=.....\0_db_connections.qvs)

Let vStart = now();

Let vReloadStart = now();

///$tab STICHPROBE

if filesize('$(vQVDCurrentYear)\$(vPlant)_STICHPROBE.qvd') >0  then

  trace >>>>>> $(vQVDCurrentYear)\$(vPlant)_STICHPROBE.qvd    ;

  MAX_TIME:

  load

     max(DTTSERF) as LAST_LOAD_TIME

  from $(vQVDCurrentYear)\$(vPlant)_STICHPROBE.qvd (qvd);

  let vLAST_LOAD_TIME =  timestamp(peek('LAST_LOAD_TIME',0,'MAX_TIME'), 'DD.MM.YYYY hh:mm:ss');

  trace >>>>>> LAST_LOAD_TIME:  $(vLAST_LOAD_TIME);

  drop table MAX_TIME;

else

  LET vLAST_LOAD_TIME = '$(vStartDate)';

  trace >>>>>> LAST_LOAD_TIME:  $(vLAST_LOAD_TIME);

end if

// load new values

STICHPROBE:

LOAD

    '$(vPlant)' as Plant,

    *;

SQL SELECT

*

FROM $(vPlantAutor).STICHPROBE

WHERE DTTSERF > to_timestamp('$(vLAST_LOAD_TIME)', 'DD.MM.YYYY HH24:MI:SS');

// load prior values

if filesize('$(vQVDCurrentYear)\$(vPlant)_STICHPROBE.qvd') >0  then

concatenate(STICHPROBE)

load

*

from $(vQVDCurrentYear)\$(vPlant)_STICHPROBE.qvd (qvd);

end if

// store all values

store STICHPROBE into $(vQVDCurrentYear)\$(vPlant)_STICHPROBE.qvd;

LET vSTICHPROBE_LOAD_DURATION = Interval(now() - vStart) ;

LET vStart = now();

LET vSTICHPROBE_Size = num(filesize('$(vQVDCurrentYear)\$(vPlant)_STICHPROBE.qvd')/1024,'00.0') & ' KB';

LET vSTICHPROBE_Records = QvdNoOfRecords ('$(vQVDCurrentYear)\$(vPlant)_STICHPROBE.qvd');

Output from=WeekStart(Today())

This looks good to me, give it a shot with your if statement and see if it works or not

[amit_saini]

So you think this below might work???

Let vLoadFrom = timestamp(If(Weekday($(vLAST_LOAD_TIME)) >= 5, WeekStart($(vLAST_LOAD_TIME)), $(vLAST_LOAD_TIME)), 'DD.MM.YYYY HH24:MI:SS');

Thanks

I don't think that it will always give you monday. Instead try

Let vLoadFrom = timestamp(If(Weekday($(vLAST_LOAD_TIME)) >= 5, ($(vLAST_LOAD_TIME)-5), $(vLAST_LOAD_TIME)), 'DD.MM.YYYY HH24:MI:SS');

[amit_saini]

So Kushal this below is not required:

let vLAST_LOAD_TIME =  timestamp(peek('LAST_LOAD_TIME',0,'MAX_TIME'), 'DD.MM.YYYY hh:mm:ss');

I have to change this with the new logic???

Thanks,

I think -5 would be an issue on a Saturday or Sunday refresh. I don't see why WeekStart() won't give a Monday all the time Kush?

[sunny_talwar]

I think it should work. Only other thing to check is Num(WeekDay(Today())) to ensure that you get 1. and Num(WeekDay(Today() + 5)) gives you 5, Num(WeekDay(Today() + 6)) gives 6 and Num(WeekDay(Today() + 7)) gives 7 in a text box object

[amit_saini]

Num(WeekDay(Today())) and Num(WeekDay(Today() + 7)) giving me 0 in text box

Rest 5 and 6 is fine.

Thanks,

Then try this:

LET vLoadFrom = TimeStamp(If(Num(WeekDay($(vLAST_LOAD_TIME))) >= 6 or Num(WeekDay($(vLAST_LOAD_TIME))) = 0, WeekStart($(vLAST_LOAD_TIME)), $(vLAST_LOAD_TIME)), 'DD.MM.YYYY HH24:MI:SS');

The one last thing that concerns me is the this date format -> DD.MM.YYYY HH24:MI:SS

I don't think QlikView will recognize this, may be you want this -> DD/MM/YYYY hh:mm:ss

LET vLoadFrom = TimeStamp(If(Num(WeekDay($(vLAST_LOAD_TIME))) >= 6 or Num(WeekDay($(vLAST_LOAD_TIME))) = 0, WeekStart($(vLAST_LOAD_TIME)), $(vLAST_LOAD_TIME)), 'DD/MM/YYYY hh:mm:ss');

[amit_saini]

I think this has to be like this:

'DD.MM.YYYY hh:mm:ss'

Let me give a try!

Thanks,
