Ibatis ORA-00936: 缺失表达式 异常原因之一

用ibatis2.0做持久层开发，出现以下异常：

com.ibatis.common.jdbc.exception.NestedSQLException:   
--- The error occurred while applying a parameter map.  
--- Check the FINGERDB_MANAGERINFO.countByParams-InlineParameterMap.  
--- Check the statement (query failed).  
--- Cause: java.sql.SQLException: ORA-00936: 缺失表达式

Caused by: java.sql.SQLException: ORA-00936: 缺失表达式

 经排查，错误在此处：

<isNotEmpty prepend="AND" property="deptnos">
  	 			<iterate prepend="AND" property="deptnos" open="(" close=")" conjunction="or">
  	 				DEPTNO = #deptnos[]#
  	 			</iterate>
  	 		</isNotEmpty>

 去掉

prepend="AND"

 改成以下即可。

<isNotEmpty prepend="AND" property="deptnos">
  	 			<iterate property="deptnos" open="(" close=")" conjunction="or">
  	 				DEPTNO = #deptnos[]#
  	 			</iterate>
  	 		</isNotEmpty>
