# Calculate field by age range

## Calculate field by age range

(OP)
I am trying to create a derive field that will sum employees with life insurance for a certain age range.

For example Total life insurance for age range 00 - 29 or 30-39 etc....

### RE: Calculate field by age range

It depends on where you want to do the sum.  If you want to use DataBase Grouping you could use this SQL Derived Field:

SUM(
CASE
WHEN (SYSDATE - BIRTHDATE) BETWEEN 0 AND 29 THEN 1
ELSE 0
END
)

Or if you want to do the math in the report as a Summary Field use this SQL Derived field:

CASE
WHEN (SYSDATE - BIRTHDATE) BETWEEN 0 AND 29 THEN 1
ELSE 0
END

This will return a 1 or 0 for each record.  You would then click on the column of 1s and 0s and hit the sum button.

Charles,
I am trying to get a headcount but when I use the logic listed below it only returns 5.

CASE
WHEN (SYSDATE - BIRTHDATE)  BETWEEN 0 AND 29  THEN 1
WHEN (SYSDATE - BIRTHDATE)  BETWEEN 30 AND 39  THEN 2
WHEN (SYSDATE - BIRTHDATE)  BETWEEN 40 AND 49  THEN 3
WHEN (SYSDATE - BIRTHDATE)  BETWEEN 50 AND 59 THEN 4
else 5
end

### RE: Calculate field by age range

Charles,

I also tried the code listed below and still receiving only 5.

CASE
when trunc((SYSDATE - "PS_PERSONAL_DATA"."BIRTHDATE")) < 5 then 1
when trunc((SYSDATE - "PS_PERSONAL_DATA"."BIRTHDATE")) < 10 then 2
when trunc((SYSDATE - "PS_PERSONAL_DATA"."BIRTHDATE")) < 15 then 3
when trunc((SYSDATE - "PS_PERSONAL_DATA"."BIRTHDATE")) < 20 then 4
Else 5
end

### RE: Calculate field by age range

trunc(SYSDATE - "PS_PERSONAL_DATA"."BIRTHDATE") returns a value in days.  To get years divide by 365.

Try this:

CASE
when TRUNC((SYSDATE - "PS_PERSONAL_DATA"."BIRTHDATE") / 365) < 5 then 1
when TRUNC((SYSDATE - "PS_PERSONAL_DATA"."BIRTHDATE") / 365) < 10 then 2
when TRUNC((SYSDATE - "PS_PERSONAL_DATA"."BIRTHDATE") / 365) < 15 then 3
when TRUNC((SYSDATE - "PS_PERSONAL_DATA"."BIRTHDATE") / 365) < 20 then 4
Else 5
end
