Hi,
I am trying to run a simple project using active record 2.0 with MS
Sql Server Compact Edition and getting exceptions.
Here is the code I am trying to run.
class Program
{
static void Main(string[] args)
{
string dbPath = Environment.GetFolderPath
(Environment.SpecialFolder.ApplicationData) + "\\DatabaseApp";
if(!Directory.Exists(dbPath))
Directory.CreateDirectory(dbPath);
string dbFile =dbPath + "\\Data.sdf";
if (File.Exists(dbFile))
File.Delete(dbFile);
IDictionary<string,string> properties = new
Dictionary<string,string>();
properties.Add("connection.driver_class",
"NHibernate.Driver.SqlServerCeDriver");
properties.Add("dialect",
"NHibernate.Dialect.MsSqlCeDialect");
properties.Add("connection.provider",
"NHibernate.Connection.DriverConnectionProvider");
properties.Add("proxyfactory.factory_class",
"NHibernate.ByteCode.Castle.ProxyFactoryFactory,
NHibernate.ByteCode.Castle");
properties.Add("connection.connection_string", "Data
Source="+dbFile + ";");
properties.Add("show_sql", "true");
InPlaceConfigurationSource config = new
InPlaceConfigurationSource();
config.Add(typeof(ActiveRecordBase),properties);
SqlCeEngine engine = new SqlCeEngine("Data Source=" +
dbFile);
engine.CreateDatabase();
ActiveRecordStarter.Initialize(config,
new Type[]
{
typeof(Record)
}
);
ActiveRecordStarter.CreateSchema();
Record part = new Record();
part.Create();
}
namespace DatabaseApp.TestStorage
{
[ActiveRecord]
public class Record:ActiveRecordBase<Record>
{
private Record()
{
}
public Record(string name)
{
this.Name = name;
}
[PrimaryKey]
public long RecID
{
get;
private set;
}
[Property(Unique=true) ]
public string Name
{
get;
private set;
}
}
}
Here is the exception I am getting
Castle.ActiveRecord.Framework.ActiveRecordException was unhandled

InnerException:
Sql getting generated
NHibernate: INSERT INTO Record (Name) VALUES (@p0);@p0 = 'test'
NHibernate: select @@IDENTITY
Any idea why I am getting this exception?
Some more info
Setting Record.RecID to [PrimaryKey(PrimaryKeyType.Assigned) ] works
but none of the Auto generators work.
Thank you
