NHibernate的。 SessionFactory.Delete删除所有表

Question

我尝试从https://github.com/jagregory/fluent-nhibernate/wiki/Getting-started运行示例，但在运行下一个代码后，所有表都被清除。我不明白为什么会这样。我希望将删除商店var barginBasin = new Store { Name = "Bargin Basin" };以及此商店StoreProduct的表Store_id中的行。

using (var session = sessionFactory.OpenSession())
{
    session.Delete(session.CreateCriteria(typeof (Store)).List<Store>()[0]);
    session.Flush();
}

sessionFactory初始化：

var dbConfig = OracleDataClientConfiguration.Oracle10
                      .ConnectionString(c => c.FromConnectionStringWithKey("Oracle"))
                      .Driver<OracleDataClientDriver>()
                      .ShowSql();

                    sessionFactory = Fluently.Configure()
                      .Database(dbConfig)
                      .Mappings(m => m.FluentMappings.AddFromAssemblyOf<Employee>())
                      .BuildSessionFactory();

App.config中：

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <startup> 
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
    </startup>
    <connectionStrings>
        <add name="Oracle"
             connectionString="DATA SOURCE=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=[IP])(PORT=[PORT]))(CONNECT_DATA=(SERVICE_NAME=XE)));PASSWORD=[PASSWORD];PERSIST SECURITY INFO=True;USER ID=[USER ID]"
             providerName="Oracle.DataAccess.Client" />
    </connectionStrings>
</configuration>
