## Calculate Age

Sometimes you have to delete the fraction part (floor) and sometimes you have to round up to the next integer (ceiling) to get the correct age. Here are two examples (assume the first date as DOB, and the second as the day the age is calculated on):select datediff(day, '10/23/2006', '5/23/2008')/365.25, datediff(day, '5/23/1899', '5/23/2008')/365.25returns1.582477 108.999315To get the right age in integer value, we have to floor the first value(1.582477), and ceiling the second value (108.999315). Given that, I'd alter the original function by adding the second date as a parameter as well. Then you can pass getdate() or any other date as the second param. -Prabhakar Mark Ingalls Forum Newbie Group: General Forum Members Points: 2 Visits: 33 How 'bout this?`declare @dob as datetimeselect @dob = '6/21/1968'declare @now as datetimedeclare @year_diff as tinyintselect @now = getdate()select @year_diff = datediff(year, @dob, @now)if DateAdd(year, @year_diff, @dob) > @now select @year_diff -1else select @year_diff`basically, calculate the number of years that have gone by, then add those years back to the date of birth. if the resulting date is in the future, we subtract one from the years as it would indicate that we have not yet reached the birthday in the current year. if the resulting date is in the past, we have already reached the birthday in this year, so we can return the number of years unaltered.thanks,mark Dmitriy Burtsev Old Hand Group: General Forum Members Points: 358 Visits: 445 Thank you for ideacreate function dbo.Calc_Age (@dob datetime) -- date of birthreturns intasbeginreturn ( select datediff (year, @dob,v_date) - case when (month(@dob) = month(v_date) and day(@dob) > day(v_date)) then 1 when month(@dob) > month(v_date) then 1 else 0 end from dbo.v_getdate )end Maysarah Mr or Mrs. 500 Group: General Forum Members Points: 515 Visits: 145 Mark, your Idea is very nice wasekm2001 Forum Newbie Group: General Forum Members Points: 1 Visits: 1 Hello, Mark Ingalls, This is Wasek, I am just a beginer in this business, but I am eager to get the solution of calculating a person's age and date difference from one date to another for my project. Could you pl make a sample project with those in VB 2008, Zip it and send it across to my e-mail address below I willbe pleased.wasekm2001@yahoo.com One more thing, if you know. Which I could not do. That, how can I change the page setup of a print form component. Meaning to say that its paper size and the margins are auto set. How can I set it my self of my desire. If you know give me easy solution. Again I need a sample project of yours in VB 2008, considering my capability as a learner. Thanks a lot.
