SubSonic and Stored Procedures

问题

When using SubSonic, do you return the data as a dataset or do you put that in a strongly typed custom collection or a generic object?

I ran through the subsonic project and for the four stored procs I have in my DB, it gave me a Sps.cs with 4 methods which return a StoredProcedure object.

If you used a MVC, do you usually use the StoredProcedure object or wrap that around your business logic and return a dataset, list, collection or something else?

Are datasets still the norm or is that replaced by something else?

回答1:

If the results of the stored procedure has the same schema as one of your tables, you can build a collection using this code (SubSonic 2.1):

ProductCollection coll = new ProductCollection();
coll.LoadAndCloseReader(SPs.GetProducts(1).GetReader());

回答2:

ExecuteTypedList<> is your best friend in this case:

IList<Product> list=SPs.GetProducts().ExecuteTypedList<Product>();

回答3:

If my stored procedure returns all the fields from one of the tables for which I have a SubSonic object then I do a LoadAndCloseReader on the result of the stored procedure. If my stored procedure returns data that does not match a SubSonic object then I just work with it as a dataset.

回答4:

Perhaps return a datareader and then iterate it to populate some custom objects. Alternatively the quick and dirty way (since you're not using domain driven design) create a view in the DB with the same structure as the stored proc, then load the result into your ViewObjectCollection similar to John's code.

You can do data readers, but that's so 1999. Returning objects is a breeze with SubSonic, and easier to use than a data reader. You can retrieve objects like so:

Dim Charts As Generic.List(Of MusicDB.Billboard) = _
    New SubSonic.Select(MusicDB.DB.Repository.Provider, New String() _
    {"Prefix", "Artist", "Track", "ArtistNarrowToken", "TrackNarrowToken", "ArtistId", "TrackId", "TrackYear"}). _
    From(MetadataTagger.MusicDB.Tables.Billboard). _
    Where(MusicDB.Billboard.Columns.ArtistNarrowToken).IsLessThan(10). _
    Or(MusicDB.Billboard.Columns.TrackId).IsNull(). _
    OrderAsc(New String() {"TrackYear"}).ExecuteTypedList(Of MetadataTagger.MusicDB.Billboard)()
