calculate age based on dob
hi all;
I have seen posts on numerous websites to get the age from a dob column I am faced with the same problem but get this error: Server: Msg 403, Level 16, State 1, Line 1 Invalid operator for data type. Operator equals divide, type equals datetime. when I run the following query: SELECT ROUND((currentdate - DOB)/365.24,0) FROM FL1_A_Backup All I need is a simple statement that calcualtes the age from the dob column(smalldatetime) then creates a new row which it puts the data into. I have already created a CurrentDate column which has a (getdate()) value attached to it. This is nothing fancy or complicated and I just need to figure out from the year I'm not really concerned about if the person has a bday tomorrow or so on. I know I am probably doing something wrong with this query and am not shy to say that I have only been using ms sql for a couple of months (basic select statements).

you do not need a column for the current date --
Code:
select year(getdate())
- year(DOB)
- case when month(DOB) > month(getdate()) then 1
when month(DOB) < month(getdate()) then 0
when day(DOB) > day(DOB) then 1
else 0
end as age
from FL1_A_Backup
