Where are micro orm tools positioned in the application architecture
===

Simple statements like this: "Select x,y,z From Customer" are in the Data Access Layer.

If there would be logic in the query like filtering for customers from a certain city I would have to put the filtering in my business layer and do it on the in-memory customer collection.

When I regard now the Micro ORM tools they often show Sql statements with logic like:

    var a = db.SingleOrDefault<Product>("SELECT * FROM SalesLT.Product WHERE ProductID = @0, 123);

Where should I put now this line of code? In the Business Layer or the Data Access Layer?

There is logic inside the statement which should belong in Business Layer. But then I have 

Select statements inside my BLL ?? 

This is all confusing.
