I just wanna ask something and also a little code too.

As of now I have the codes that i needed except for one.

My question is How can i update the age in the database using vb.net?

For example if the person Birthdate(MM/dd) = System.Date.Today(MM/dd) then
Age + 1

Something like that, how can i use that in vb.net and access database.

Solution 1

Why do you need to? There is absolutely no point in storing this value in the database because it will be incorrect 99% of the time. Store only the birthdate, then when you need to display the age on a view or printed report, calculate it at the time of display from today's date and the DOB from the database.

Solution 2

As Richard MacCutchan has mentioned, you need to use query to calculate age. You don't need to store its value in a database.

SQL

SELECT [BirthDate], Date() AS [Today], DateDiff("yyyy", [BirthDate], Date())  AS [Age]

MS Access: Date() function[^]
MS Access: DateDiff function[^]
