我使用下面的代码查询CRM 2011中的约会集。当我使用此查询时,它返回数据,但它返回重复项。如果我取出外连接,它根本不返回任何东西。有想法该怎么解决这个吗?
<fetch>
<entity name="appointment">
<attribute name="scheduledstart" />
<link-entity name="systemuser" from="systemuserid" to="ownerid" link-type="outer">
<attribute name="firstname" alias="ownerFirstName" />
<attribute name="lastname" alias="ownerLastName" />
</link-entity>
<link-entity name="contact" from="contactid" to="new_contactperson" link-type="outer">
<attribute name="parentcustomerid" alias="parentaccount" />
<attribute name="new_businessunit" alias="businessunit" />
</link-entity>
<attribute name="new_contactperson" />
<attribute name="subject" />
<attribute name="new_coldernotes" />
<link-entity name="activityparty" from="activityid" to="activityid" link-type="outer">
<attribute name="participationtypemask" alias="participationtypemask" />
<filter>
<condition attribute="participationtypemask" operator="eq" value="5" />
</filter>
<link-entity name="contact" from="contactid" to="partyid" link-type="outer">
<attribute name="fullname" alias="RequiredContactFullName" />
</link-entity>
<link-entity name="systemuser" from="systemuserid" to="partyid" link-type="outer">
<attribute name="fullname" alias="RequiredOwners" />
</link-entity>
<link-entity name="account" from="accountid" to="partyid" link-type="outer">
<attribute name="name" alias="RequiredAccount" />
</link-entity>
</link-entity>
<!--the new join-->
<link-entity name="activityparty" from="activityid" to="activityid" alias="optionalactivityparty" link-type="outer">
<attribute name="participationtypemask" alias="optionalparticipationtypemask" />
<filter>
<condition attribute="participationtypemask" operator="eq" value="6" />
</filter>
<link-entity name="contact" from="contactid" to="partyid" alias="optionalcontact" link-type="outer">
<attribute name="fullname" alias="OptionalContactFullName" />
</link-entity>
<link-entity name="systemuser" from="systemuserid" to="partyid" alias="systemuser2" link-type="outer">
<attribute name="fullname" alias="OptionalOwners" />
</link-entity>
<link-entity name="account" from="accountid" to="partyid" alias="optionalaccount" link-type="outer">
<attribute name="name" alias="OptionalAccount" />
</link-entity>
</link-entity>
<filter type="and">
<condition attribute="scheduledstart" operator="on-or-after" value="@FromDate" />
<condition attribute="scheduledstart" operator="on-or-before" value="@ToDate" />
</filter>
</entity>
</fetch>

来指示您需要不同的记录集<fetch distinct='true'>
