The solution.

Variable:           age (today(),BirthDateTTime) (AS Age_exp)

Expr:                if($(AGE_exp) <=7 ,1,0)

Re: exclusion criteria (age)

hi,

First Calculate the age at script level

if(round(num(today()) - num(Date#( Aug 30 1965 12:00AM ,'MMM DD YYYY hh:mm))) <=7,'Y','N')      as AGE_IND

And use this field in your expression as

Sum({<AGE_IND={"Y"}>} Amount)

Re: exclusion criteria (age)

Load

     BirthDateTTime

from xyz

where BirthDateTTime < addmonths(Today(), -84);

Something like this perhaps, or if you want to create a flag,

load

     if(BirthDateTTime<addmonths(Today(), -84), 1, 0) as OlderThan7YearsFlag

from xyz..

Or you can do it in a set analysis expression in the front end.

It all depends on how/where you want to use the filtering.

Re: exclusion criteria (age)

Both solutions won't work.

the today() format is 10/22/2012

and the BirthDateTTime is Aug 30 1965 12:00AM.
Could this be the problem?

Re: exclusion criteria (age)

hi,

Thats the reason y I have used the num function to convert both the fields to numeric.

Re: exclusion criteria (age)

Try using Timestamp#() to interpret the long string value as a timestamp. Date#() might disregard the time part of the value.

Re: exclusion criteria (age)

hi

Try in the textbox,whether the timestamp#() function gives the value or not? then if it gives, means check with the above expression, from that you can identify it..

hope it helps

Re: exclusion criteria (age)

hi,

Since its chr(50) , qlikview might be considering as text and hence you might have to convert into datetime.

YOu might have to break the text using subfield function or use the left , right function to get the result.

And use the makedate function to convert into date.

eg:

SubFiled(Aug 30 1965 12:00AM,' ',3)   This will get you 1965 i.e Year

SubFiled(Aug 30 1965 12:00AM,' ',1)  This will get you Aug  further convert into number  num(date#('AUG','MMM'))  i.e  8

SubFiled(Aug 30 1965 12:00AM,' ',2)  This will get you 30.

Now use the makedate function like below

num(Makedate(1965,8,30)

I hope you got my point.
