Subsonic 3 - Insert of Update

Question

Currently using Subsonic 3 with Activerecord. Purely out of curiosity, is there an easy way to update or insert a record in a clean and consise way?

Instead of

 var record = MyModal.SingleOrDefault(x => x.id == 1)
 if (record != null)
 {
     // code to update record here
 } else {
    // code to insert a record here
    MyModal record = new MyModal();
    record.attribute1 = "blah"
    ... blah blah
 }

Answer 1

The standard ActiveRecord templates provide a Save() method, which either calls Add() or Update() depending on whether the object IsNew(). It should work in the sample you gave.

Answer 2

You should also be able to do it like this:

            // perform insert with a linq expression
            db.Insert.Into<PARTS_VI_PART_NUMBER>(
                x => x.ITEM_NUMBER,
                x => x.ITEM_CLASS_CODE,
                x => x.ITEM_DESCRIPTION,
                x => x.MANUFACTURER
            ).Values(
                "TEST",
                "TEST",
                "TEST",
                "TEST"
            ).Execute();

            // update using linq expression
            db.Update<PARTS_VI_PART_NUMBER>()
                .Set(x => x.ITEM_DESCRIPTION == "UPDATED",
                     x => x.ITEM_CLASS_CODE == "UPDATED2")
                .Where(x => x.ITEM_NUMBER == "TEST")
                .Execute();

            // delete inserted row with a linq expression
            db.Delete<PARTS_VI_PART_NUMBER>(x => x.ITEM_NUMBER == "TEST").Execute();

At least that is how I've been doing it in one of my projects. The Insert(), Update() and Delete() methods are generated by Context.tt into the Context.cs file (I am using the "ActiveRecord" T4 files).

Edit

Oh I'm sorry, when I forst read your question, I thought you were asking for an easier way to "Insert" or "Update", but after re-reading it, I realized you are asking for "Insert, or Update if it already exists" like doing an 'upsert'.

Sorry, my answer doesn't really cover that. I don't know of a good way to do it either. I usually just end up doing what you are doing... try to select it, and if I get no results, do the insert.
