Conditional Creation of QVD's

[don_qlikview]

Hello Everyone,

I am new to qlikview and I am trying to create QVD's based upon conditional evaluation of a field. For example I am having a field called

Run Time

02/02/2014 11:00:00 AM

So, I want to make a qvd based upon the time stamp. So, I am writing something like

if(TimeStamp([Run Time], 'hh:mm:ss' = '11:00:00') then

Store abc into 11AM.qvd;

else

if(TimeStamp([Run Time], 'hh:mm:ss' = '12:00:00') then

Store abc into 12PM.qvd;

end if;

Can anyone tell me if I am writing this correctly?

Thanks,

Don

Instead of an IF statement how about setting a variable to the value of the Hour and using that to define the qvd name ?

// Instead of '02/02/2014 11:00:00 AM' use your field name {Run Time]

let Run Time= Hour(date#('02/02/2014 11:00:00 AM' , 'DD/MM/YY hh:mm:ss TT') ) ;

// the trace function displays the value of variable vHour when reloading

trace $(vHour) ;

//

// I prefer 24 hour clock hour, so that is what this is using and the value of vQVD is 11.qvd

let vQVD = '$(vHour)' & '.qvd' ;

// the trace function displays the value of variable vQVD when reloading

trace $(vQVD) ;

// this stores resident table abc into a qvd called 11.qvd

store abc into $(vQVD) [qvd] ;

Bill's suggestion is a good one, but first you must convert your field [Run Time] into a variable. Fields are not directly accessible from a position outside a Load statement. One way to do this is to use the Peek() function. If you want to use the time stamp from the last record, you should write

     Let vTimeStamp = Peek('Run Time',-1,'TableName') ;

or

     Let vHour = Hour(Peek('Run Time',-1,'TableName')) ;

and then use the variable in your Store statement.
