just fyi, the examples i gave are really simplified. In the actual model the parent will have multiple childrenlists and the objects more properties. Excuse my ignorance, but what is n + 1 select problem?

Off hand, I'd say look at the methods for loading complex types and strategies to avoid what's known as the "N + 1 select" problem. I don't think multiple recordsets is your best solution if I understand your situation properly. _____ From: Miika Mäkinen [mailto:[EMAIL PROTECTED] Sent: Wednesday, May 23, 2007 10:49 PM To: [email protected] Subject: Multiple resultsets in data mapper Hi All, I'm just getting into iBatis, and I'd like to if it can handle multiple resultsets (.Net 2.0, Sql Server 2005) For example, I'd have an objects like (pseudo-code): class Company { int Id; string Name; List<Classification> Classifications; } class Classification { int Id; string Name; } And a stored procedure would return 2 resultssets: SELECT CompanyId, CompanyName FROM Company; SELECT CompanyId, ClassificationId, ClassificationName FROM CompanyClassification INNER JOIN Classification ON CompanyClassification.ClassificationId=Classification .ClassificationId; Can I some how map the 2nd returned table into "List<Classification> Classifications" inside my "Company" object?
