exclusion criteria (age)

[#1]

Ive got a problem with age selection and i hope that someone here can help me with it.

In my datawarehouse ive got the attribute BirthDateTTime (format:      Aug 30 1965 12:00AM)         

now i want to exclude people younger than 7 years old   

can someone tell me how i can make this expression?

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)

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.

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?

hi,

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

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

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

HI benn,

Can you upload a sample QVW file

[deepakk]

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.
