有條件地查詢迭代使用ibatis列表

Question

我在ibatis中使用下面的查詢遍歷列表。我想添加一個條件，因爲列表是空的。在這種情況下，我想改變condition.PFB查詢以xml：

<statement id="getSearchLateJob" parameterClass="map" resultMap="getCurrentJob_r"> 
    select a.JOBSET as "JOBSET", 
    a.JOB as "JOB", 
    a.JOB_NO as "JOB_NO", 
    a.QUALIFIER as "QUALIFIER", 
    case when year(a.START_TIME) = 1900 then null else a.START_TIME end as "EXPECTED_START_TIME", 
    case when year(a.END_TIME) = 1900 then null else a.END_TIME end as "END_TIME", 
    datediff(mi,a.START_TIME,a.END_TIME) as "DURATION", 
    b.JOB_AVG as "JOB_AVG", 
    a.STATUS as "STATUS" 
from CA_JOB_STATUS a,JOB_AVG b 
where a.JOBSET = b.JOBSET 
    and a.JOB=b.JOB 
    and a.JOBSET like #jobSet:VARCHAR# 
    and a.JOB like #job:VARCHAR#  
    <!-- and a.STATUS in --> 
    <dynamic prepend="and a.STATUS in "> 
    <iterate property= "currentJobStatusArr" open="(" close=")" conjunction=","> 
    #currentJobStatusArr[]:VARCHAR# 
    </iterate> 
    </dynamic> 
order by a.END_TIME desc, a.START_TIME desc           

在這種情況下，我怎麼能動態改變前置它遍歷一個列表，並建立IN詢問，到類似的查詢：事情是這樣的：

變化來自：

select * from table where status in (?,?) 

要：

select * from table where status like ?

我找到了解決辦法：

<dynamic prepend="and a.STATUS "> 
      <isNotEmpty property="currentJobStatusArr"> 
       <iterate property= "currentJobStatusArr" open="in (" close=")" conjunction=","> 
       #currentJobStatusArr[]:VARCHAR# 
       </iterate> 
      </isNotEmpty> 
      <isEmpty property="currentJobStatusArr" > 
       like #allRec:VARCHAR# 
      </isEmpty> 
     </dynamic>
