NHibernate ADO.NET 屬性

Property name	Purpose
connection.provider_class	The type of a custom IConnectionProvider. eg. full.classname.of.ConnectionProvider if the Provider is built into NHibernate, or full.classname.of.ConnectionProvider, assembly if using an implementation of IConnectionProvider not included in NHibernate.
connection.driver_class	The type of a custom IDriver, if using DriverConnectionProvider. full.classname.of.Driver if the Driver is built into NHibernate, or full.classname.of.Driver, assembly if using an implementation of IDriver not included in NHibernate. This is usually not needed, most of the time the dialect will take care of setting the IDriver using a sensible default. See the API documentation of the specific dialect for the defaults.
connection.connection_string	Connection string to use to obtain the connection.
connection.connection_string_name	The name of the connection string (defined in <connectionStrings> configuration file element) to use to obtain the connection.
connection.isolation	Set the ADO.NET transaction isolation level. Check System.Data.IsolationLevel for meaningful values and the database's documentation to ensure that level is supported. eg. Chaos, ReadCommitted, ReadUncommitted, RepeatableRead, Serializable, Unspecified
connection.release_mode	Specify when NHibernate should release ADO.NET connections. See Section 10.7, “Connection Release Modes”. eg. auto (default) | on_close | after_transaction Note that this setting only affects ISessions returned from ISessionFactory.OpenSession. For ISessions obtained through ISessionFactory.GetCurrentSession, the ICurrentSessionContext implementation configured for use controls the connection release mode for those ISessions. See Section 2.3, “Contextual Sessions”.
command_timeout	Specify the default timeout of IDbCommands generated by NHibernate.
adonet.batch_size	Specify the batch size to use when batching update statements. Setting this to 0 (the default) disables the functionality. See Section 17.6, “Batch updates”.

NHibernate ADO.NET 屬性

屬性名稱	用途
connection.provider_class	實現IConnectionProvider介面的類型。 例如： （如果是NHibernate內部的IConnectionProvider實作類別）full.classname.of.ConnectionProvider，（如果是自訂的NHibernate外部的IConnectionProvider實作類別 ）full.classname.of.ConnectionProvider, assembly。
connection.driver_class	如果使用DriverConnectionProvider，實現IDriver介面的類型。 （如果是NHibernate內部的實現的IDriver類型）full.classname.of.Driver （如果是自訂的NHibernate外部的IDriver實作類別 ）full.classname.of.Driver, assembly。 這個配置通常是不需要配置的，如果設定好了hibernate.dialect一般會自動選好對應的IDriver。 詳細的dialect與IDriver的預設對應關係可以查看API文檔。
connection.connection_string	資料庫連接字串
connection.connection_string_name	資料庫連接字串名稱(定義在.Net設定檔<connectionStrings>配置節裡面的連接字串名。
connection.isolation	ADO.NET交易隔離等級， 查看System.Data.IsolationLevel類來瞭解各個值的具體意義, 但請注意多數資料庫都不支援所有的隔離等級. 例如： Chaos, ReadCommitted, ReadUncommitted, RepeatableRead, Serializable, Unspecified
connection.release_mode	指定ADO.NET何時釋放資料庫連接。查看10.7 串連釋放模式. 例如： auto (預設) | on_close | after_transaction 注意,這些設定僅對通過ISessionFactory.OpenSession得到的ISession起作用。對於通過ISessionFactory.GetCurrentSession得到的ISession， 所配置的ICurrentSessionContext實現控制這些ISession的串連釋放模式。 請參閱2.3. 上下文相關的（Contextual）Session擷取更多資訊。
command_timeout	指定NHibernate產生的IDbCommands對象的逾時時間。 .
adonet.batch_size	指定用ADO.Net的批次更新的數量，預設設定為0（不啟用該功能）。請參閱 16.6. 批次更新.
