Subsonic: dynamic connections

Question

I have an ancient mess I\'m trying to shovel into tiers using subsonic. Trouble is, I have this scenario:

When Hal logs in, his login uses database X for lookup data

Answer 1

Another example of changing providers on the fly (at runtime). This one reads items from one database and saves them to another.

Use:

CopyToAnotherDB(Dock.Columns.Id, Dock.BarcodeStringColumn);

Method:

    public static void CopyToAnotherDB(string identifierColumnName, TableSchema.TableColumn fakeDirtyColHack)
        where E : ActiveRecord, new()
    {
        SqlQuery q = new Select().From();
        q.ProviderName = SERVU_PROVIDER;
        IList list = q.ExecuteTypedList();

        string connStr = ConfigurationManager.ConnectionStrings[ARCHIVE_PROVIDER].ConnectionString;
        using (SharedDbConnectionScope scope = new SharedDbConnectionScope(connStr))
        {
            foreach (E item in list)
            {
                int itemID = (int)item.GetColumnValue(identifierColumnName);
                SqlQuery qry = new Select(identifierColumnName).From().Where(identifierColumnName).IsEqualTo(itemID);
                int recCount = qry.GetRecordCount();
                E obj = item.Clone();

                obj.IsNew = recCount == 0; //determines if adding or updating
                obj.IsLoaded = !obj.IsNew; //determines if adding or updating
                obj.DirtyColumns.Add(fakeDirtyColHack);
                obj.Save();
            }
        }
    }
