Asp – Insert record with Subsonic 3.0

First and foremost: the t4 templates are there for you to change as needed with SS3. That was the main idea with using T4 - I don't want to back you into my silliness :).

To the question at hand - I think this might be a bug in our templates that refuses to stick a value into the PK field:

    ISqlQuery BuildInsertQuery(T item) {
        ITable tbl = _db.FindTable(typeof(T).Name);
        Insert query = null;
        if (tbl != null) {
            var hashed = item.ToDictionary();
            query = new Insert(_db.Provider).Into<T>(tbl); ;
            foreach (string key in hashed.Keys) {
                IColumn col = tbl.GetColumn(key);
                if (!col.IsPrimaryKey) {
                    query.Value(key, hashed[key]);
                }
            }
        }
        return query;
    }

In this, our check should actually be...

                if (!col.IsPrimaryKey && !col.AutoIncrement) {
                    query.Value(key, hashed[key]);
                }

In this way, the non-identity will be inserted. But in reading your issue here, it sounds to me like you're not trying to insert into a non-identity.

The email you sent me doesn't say anything about PKs as identity - your PK was a thing called "NAme" which is a string type and not and identity (auto-increment).

I'm wondering about when I cannot get around this issue--when I have to add a new record to the database and have an identity as my primary key.

This is what SubSonic assumes - that your PK is an IDENTITY column. If you ONLY have an IDENTITY column, we can't help you because this is a deadlocked table in that you can't insert any value into it, therefor you can't tick the IDENTITY column. Your only recourse at this point is to SET IDENTITY INSERT="off", which defeats the purpose.

Hopefully this will answer your question? If I'm not getting it - can you do this for me:

1. One sentence: what can't you do and what's the error
2. What did you expect

Thanks Will and I hope I'm not being thick.

1. Create DAL object

2. Assign values to all properties except primary key property

3. Call Save()

Subsonic takes care of the identity keys itself you need not worry.
