That's why the ObjectMapper .NET does not support it natively. What you can do is, executing a native SQL Select where you put your SELECT String into the Execute Method. <code> /* * Get the low level Native Persister from the SQL Persister */ INativePersister nativePersister = sqlPersister as INativePersister; // First example without Parameter nativePersister.Execute("EXEC dbo.SayHello"); // Second example is using Parameters nativePersister.ExecuteWithParameter("EXEC dbo.SayHello @p01", "Peter"); </code> Also have a look at the query API of the ObjectMapper .NET http://blog.objectmapper.net/2007/01/22/how-to-build-sql-queries/ Database Engines have sometimes very different ways to do a fulltext search.

/*
* Get the low level Native Persister from the SQL Persister
*/
INativePersister nativePersister = sqlPersister as INativePersister;

// First example without Parameter
nativePersister.Execute("EXEC dbo.SayHello");

// Second example is using Parameters
nativePersister.ExecuteWithParameter("EXEC dbo.SayHello @p01", "Peter");

But for short: A Where is called a Condition when using the AdFactum ObjectMapper .NET. There're several conditions, like ConditionList, AndCondition, OrCondition, InCondition, NotInCondition and more. What you're searching for is a AndCondition with a NotEqual Query Operator, like: new AndCondition (typeof(Person),'Name', QueryOperator.NotEqual, 'Mike'); Hope I could help you. Cheers Gerhard Hi (unkown) :) ,
