I be way off, but at first glance, isn't wrapping things in a using statement going to ensure that the resources are closed? I'm not sure that's what you want to do. We always let iBatis manage the connections automatically. Of course, I haven't profiled to see what it actually does.
_____ From: Dorin Manoli [mailto:[EMAIL PROTECTED] Sent: Friday, May 04, 2007 5:44 AM To: [email protected] Subject: Sessions Hi everybody. I got a little trouble with connections. First I will start with a brief description of my Application. I got a Class Library which includes iBATIS XML files, persistent classes. Also in this Library is a static class Mapper which create and configure DomSqlMap and through which I can cal lISqlMapper.. I followed example from iBATIS document. Then I assigned a MAP class to each persistent class. Ex. I have Customer class then I create another class CustomerMap which contains methods for operations like Add/Update/Delete. I have couple of such class-combination. Finaly I have a WinForm application from which I call MAP classes and render information on screen. Finally the problem: I used JetBrains dotTrace profiler to optimize my code and I found that each time I call a method from MAP class iBATIS OpenConnection method is called. I thought if I'll use Sessions I will save "precious" 13ms on each OpenConnection call. So I followecd example from iBATIS Maper manual. [C#] using ( IDalSession session = sqlMap.OpenConnection() ) { Account account = sqlMap.QueryForObject("GetAccountViaColumnName", 1) as Account; } But instead of calling sqlMap.QueryObject I am using using ( IDalSession session = Mapper.Instance().OpenConnection() ) { Customer cust=customerMap.GetCustomer(customerId); ....... . . . . } Inside GetCustomer I have Mapper.Instance().QueryForObject(... . . ); Profiling again I saw that OpenConnection is invoked again. Something went wrong, but couldn't find in any manual how to properly use Session. Also looking in unit tests Ididn't found answers. Cheers.
