Mybatis Oracle 批量插入

以下是批量插入的demo  大家可以参考，也算我爬过的坑

  
--- 带序列主键的批量插入  
  <insert id="addCheckDetail" parameterType="java.util.List">  
            INSERT INTO CHECK_DETAIL(  
                CHECK_id,CHECK_DATE,CHECK_WEEK,EMP_CODE,CHECK_TIME,CHECK_LATE,CHECK_LEAVE_EARLY,  
                CHECK_EXCEPTION,CHECK_WORK_OVERTIME,EMP_NAME,DEPT_NAME,CHECK_LATE_TIME,DESCRIPTION  
              )  
              select CHECK_DETAIL_SEQ.NEXTVAL,cd.* from(  
              <foreach collection="list" item="item" index="index" separator="union all">  
                  select  
                    #{item.checkDate,jdbcType=VARCHAR},  
                    #{item.checkWeek,jdbcType=VARCHAR},  
                    #{item.empCode,jdbcType=VARCHAR},  
                    #{item.checkTime,jdbcType=VARCHAR},  
                    #{item.checkLate,jdbcType=VARCHAR},  
                    #{item.checkLeaveEarly,jdbcType=VARCHAR},  
                    #{item.checkException,jdbcType=VARCHAR},  
                    #{item.checkWorkOverTime,jdbcType=VARCHAR},  
                    #{item.empName,jdbcType=VARCHAR},  
                    #{item.deptName,jdbcType=VARCHAR},  
                    #{item.checkLateTime,jdbcType=VARCHAR},  
                    #{item.description,jdbcType=VARCHAR}  
                    from dual  
                </foreach>  
                ) cd  
        </insert>
