CRM FetchXML獲取超過5000條記錄

Question

我有超過5000條記錄要使用此查詢獲取，但每次都獲得空值的cookie。我意識到鏈接實體是這裏的問題，因爲當我刪除它時，我每次都會得到cookie。

<fetch version="1.0" mapping="logical" distinct="true" page="1" count="2000" > 
    <entity name="listmember" > 
     <link-entity name="contact" from="contactid" to="entityid" alias="c" > 
      <attribute name="contactid" /> 
      <attribute name="telephone1" /> 
      <link-entity name="phonecall" from="ic_customer" to="contactid" alias="pc" link-type="outer" distinct="true"> 
       <attribute name="activityid" /> 
       <filter type="and" > 
        <filter type="or" > 
         <condition attribute="statuscode" operator="eq" value="1" /> 
         <condition attribute="ic_end" operator="on-or-after" value="2016-11-12" /> 
        </filter> 
       </filter> 
      </link-entity> 
      <filter type="and" > 
       <condition attribute="statecode" operator="eq" value="0" /> 
       <condition attribute="telephone1" operator="not-null" /> 
       <condition attribute="donotphone" operator="eq" value="0" /> 
      </filter> 
     </link-entity> 
     <filter type="and" > 
      <condition attribute="listid" operator="in" > 
       <value> 
        {f89087ef-7017-e611-80e3-5065f38a3951} 
       </value> 
      </condition> 
      <condition entityname="pc" attribute="activityid" operator="null" /> 
     </filter> 
    </entity> 
</fetch> 

任何人都知道如何獲得這個請求的分頁cookie？

這個問題的解決方案是你需要在根實體上指定ID列。在此示例中，您需要將listmemberid屬性添加到實體的根listmember實體。

<fetch version="1.0" mapping="logical" distinct="true" page="1" count="2000" > 
    <entity name="listmember" > 
     <attribute name="listmemberid" /> 
     <link-entity name="contact" from="contactid" to="entityid" alias="c" > 
      <attribute name="contactid" /> 
      <attribute name="telephone1" /> 
      <link-entity name="phonecall" from="ic_customer" to="contactid" alias="pc" link-type="outer" distinct="true"> 
       <attribute name="activityid" /> 
       <filter type="and" > 
        <filter type="or" > 
         <condition attribute="statuscode" operator="eq" value="1" /> 
         <condition attribute="ic_end" operator="on-or-after" value="2016-11-12" /> 
        </filter> 
       </filter> 
      </link-entity> 
      <filter type="and" > 
       <condition attribute="statecode" operator="eq" value="0" /> 
       <condition attribute="telephone1" operator="not-null" /> 
       <condition attribute="donotphone" operator="eq" value="0" /> 
      </filter> 
     </link-entity> 
     <filter type="and" > 
      <condition attribute="listid" operator="in" > 
       <value> 
        {f89087ef-7017-e611-80e3-5065f38a3951} 
       </value> 
      </condition> 
      <condition entityname="pc" attribute="activityid" operator="null" /> 
     </filter> 
    </entity> 
</fetch>

讀你的帖子提醒我，我聽說過這個之前，果然我去我的筆記，看到「Fetchxml linkentity不支持分頁」。但是，我似乎無法找到關於限制的任何官方信息，這感覺很奇怪。

無論如何，我敢肯定它是取查詢與鏈接實體不支持分頁的情況。嘗試使用QueryExpression執行代替。
