Question

我有以下数据配置：

<document name="locations">
    <entity pk="id" name="location" query="select * from locations WHERE isapproved='true'" 
            deltaImportQuery="select * from locations WHERE updatedate &lt; getdate() AND isapproved='true' AND id='${dataimporter.delta.id}'" 
            deltaQuery="select id from locations where isapproved='true' AND updatedate &gt; '${dataimporter.last_index_time}'">

            <!-- more document fields -->

    </entity>
    <entity pk="id" name="offerdetails" query="SELECT title AS offer_title,ISNULL(img,'') AS offer_thumb,id AS offer_id
    ,startdate AS offer_startdate
    ,enddate AS offer_enddate
    ,description AS offer_description
    FROM offers WHERE objectid=${location.id} AND objecttype=${location.objecttype} AND approved='true' AND startdate &lt; getdate() AND enddate &gt; getdate()"
    deltaImportQuery="SELECT title AS offer_title,ISNULL(img,'') AS offer_thumb,id AS offer_id
    ,startdate AS offer_startdate
    ,enddate AS offer_enddate
    ,description AS offer_description FROM offers WHERE updatedate &lt; getdate() AND approved='true' AND id='${dataimporter.delta.id}'"
    deltaQuery="SELECT id FROM offers where approved='true' AND updatedate &gt; '${dataimporter.last_index_time}'"> 
        <field name="id" column="offer_id" />
        <field name="offer_title" column="offer_title" />
        <field name="offer_thumb" column="offer_thumb" />
        <field name="offer_startdate" column="offer_startdate" />
        <field name="offer_enddate" column="offer_enddate" />
        <field name="offer_description" column="offer_description" />
    </entity>                                
    </document>

现在，当[locations]表中的对象更新时，我的delta导入查询/dataimport?command=delta-import完美无缺。但是当在[offers]表中更新商品时，deltaimport命令不会看到这一点如果要约更新，是否可以通过delta导入相应位置的更新优惠？

然后没有：
一个。必须完全导入所有位置
或
湾必须更新这个单一位置，然后进行常规deltaimport？

您尝试使用嵌套实体，因此仅适用于位置表，因为增量查询更新仅基于位置日期更新。现在，您必须为商品编写增量查询，并将其视为单独的实体。

示例：

<entity pk="id" name="location" ....
  deltaImportQuery="select * ..
  deltaQuery="select ....
</entity>

<entity pk="id" name="offers" ....
  deltaImportQuery="select * ..
  deltaQuery="select ....
</entity>
