ibatis插入获取自增id

<insert id="addadjunct" parameterClass="adjunct">
	insert into t_project_adjunct(fadjunct,ftype,fcreater,fcreatetime,fdeleted) 
	values(#name#,1,#creater#,sysdate(),0)
	<selectKey keyProperty="id" resultClass="int">
	  SELECT @@IDENTITY AS ID
   </selectKey>
</insert>

主要是

<selectKey keyProperty="id" resultClass="int">
	  SELECT @@IDENTITY AS ID
   </selectKey>

语句，不过要注意返回类型
