Hi all I am trying to use a datediff to get the age of a patient at a certain time of year.

They want to set the persons age as of 06302012. This eems simple enough but I get erroneous data

I use the following datediff(YY, PAT.BIRTH_DATE, '20120630') but even if the person birth day comes after June 30 it returns the age for that year regardless of the date

02/01/2010 age will equal 2
08/01/2010 age should be 1 but comes out as 2...

mahalo, for your help

Here's the ultimate age function:

but this simple hack will work some of the time:
floor(datediff(day, PAT.BIRTH_DATE, '20120630') / 365.0)
