NHibernate: Batch Updates & Batch Inserts - 追萝驴
追萝驴 · 2010-11-05 · via 博客园 - 追萝驴

配置文件中设置:

<property name="adonet.batch_size">100</property>

这个不用说了。问题是,这么设置了,不代表必然能够真的Batch Updates 或 Batch Inserts。

对于Batch Inserts而言,不要使用会导致需要从数据库返回主键的定义方式。例如:这样的是可以的:

		<id name="ID" column="ID" type="String" >		
            <generator class="uuid.hex">
              <param name="format"> D </param>
              <param name="seperator"> - </param>
            </generator>
		</id>

同样,对于Batch Updates而言,不要使用需要从数据库返回值的方式。在什么时候需要返回值?譬如:optimistic-lock="version",就需要返回Version字段的值,Batch Updates无法实施;改用optimistic-lock="none",就没有问题。

记下,备忘。
