Unless I'm behind on my knowledge, I don't believe that iBatis.Net has
automatic optimistic concurrency implementation. You will have to
implement this yourself.
This is the pseudo of how I implemented mine:
BusinessBase<T> : IClonable
-Clone()
-OriginalObject AS T
Employee : BusinessBase<Employee>
-SSN
-FirstName
-LastName
1. Retrieve Employee
2. Clone Employee and store in OriginalObject
3. Employee is parameter class of Update Ibatis Mapping
UPDATE dbo.Employee
SET FirstName = #_firstName#
, LastName = #_lastName#
, SSN = #_ssn#
WHERE FirstName = #OriginalObject._firstName#
AND LastName = #OriginalObject._lastName#
AND SSN = #OriginalObject._ssn#
Unless you have build some kind of framework to do this, it is a lot of
manual, repetitive work. Only do it when you really need to.

Subject: TR: iBatis.Net - Optimistic concurrency control
Hello,
How to use the optimistic concurrency control when we update the
database with iBatis.Net ?
Because, when we use the <insert> or <update> elements, we can only pass
one parameter : the object to insert or to update. But there is no other
parameter to pass the data to the optimistic concurrency control.
Thank you for your help.
