Question

我在ibatis中使用以下查询来迭代列表。我想添加一个条件，因为列表是空的。在这种情况下，我想在xml：

中更改condition.PFB查询

   <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

在这种情况下，我如何更改迭代列表并构建IN查询的动态前置，以及类似的查询：这样的事情：

更改自：

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

要：

    select * from table where status like ?

我找到了解决方案：

    <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>

有条件地查询使用ibatis迭代列表
