I am learning FetchXML and am currently new to it.
I tried looking at the documentation located here but I did not find it very helpful
What does this line mean:
<fetch version="1.0" output-format="xml-platform" mapping="logical" distinct="true">
What does the mapping="logical" part mean?
What does the distinct="true" part mean?
As per FetchXML schema we have two enum values namely internal & logical for mapping attribute. We have to use mapping="logical" in our queries & internal may be for Platform usage (my guess).
<xs:attribute name="mapping">
<xs:simpleType>
<xs:restriction base="xs:NMTOKEN">
<xs:enumeration value="internal" />
<xs:enumeration value="logical" />
</xs:restriction>
</xs:simpleType>
</xs:attribute>
distinct="true" will remove the duplicate values in your resultset. This is similar to SQL concept.
Refer & read the documentation

In Microsoft Dynamics 365 FetchXML, is there a way to check a text field with the condition that it begins with "xxABC", where "xx" can be anything?
This is actually possible (to my surprise).
I created a few Account records, named:
"aacd"
"abcde"
"zxcdef"
Using _ as the placeholder for single characters I got the desired result:
<fetch top="50">
<entity name="account">
<attribute name="name" />
<filter>
<condition attribute="name" operator="like" value="__cd%" />
</filter>
</entity>
</fetch>
Under the hood this like condition appears to be translated into T-SQL. Take a look at the documentation LIKE (Transact-SQL) and have fun!
How to unmerge records which are merged from D365 OOB feature? Is there any custom code solution ?
Unfortunately, un-merging cannot be achieved in any OOB option and AFAIK, no community solutions are available.
As this is totally a rare requirement, we can build some console app for this.
We know that the master record will get/copy all the subordinate record field values after merging (based on choice in Merge screen), the subordinate record will get deactivated (still holding its original field values only). All the related records will be remapped to master record. So we have to reverse engineer all this for un-merging.
From my research, looks like the deactivated subordinate record will hold the master record as a link in masterid field. We have to pull all these records using the query below & iterate through each record, and then achieve what we want.
<fetch>
<entity name="contact" >
<attribute name="fullname" />
<attribute name="merged" />
<attribute name="masterid" />
<filter>
<condition attribute="merged" operator="eq" value="1" />
</filter>
</entity>
</fetch>
I want to retrieve records from multiple entities by matching text. Is it possible using fetchxml or web api? I want to use it by javascript.
This is certainly achievable using FetchXML. Specifically you want to use the like operator. For example the following Fetch Query searches contact name and email for a given value:
<fetch version="1.0" output-format="xml-platform" mapping="logical" distinct="false">
<entity name="contact">
<attribute name="fullname" />
<attribute name="contactid" />
<filter type="and">
<filter type="or">
<condition attribute="fullname" operator="like" value="%[Insert Dynamic Value]%" />
<condition attribute="emailaddress1" operator="like" value="%[Insert Dynamic Value]%" />
</filter>
</filter>
</entity>
</fetch>
Write a similar fetch query for each table you wish to search.
Is it possible to combine all entities together instead of requesting separately using fetchXml?
No, by design FetchXML does not support querying multiple unrelated records. Although you can query against related records in a single fetch expression, you are not able to enforce OR conditions across multiple tables. For example, you cannot write a FetchXML query comparable to the following SQL:
SELECT *
FROM contact
JOIN account on contact.accountid = account.accountid
WHERE contact.fullname like '%foo%'
OR account.name like '%foo%'
It appears to be possible, though unsupported, to access Relevance Search via an API: https://bguidinger.com/blog/relevance-search-api
I've very a lot of searching on Google and can not find the answer to this question.
We have Enterprise Magento and are using SOLR. We would like to select a group of products and put them at the top of the search results when they are returned by SOLR. We would use this for clearance products, etc.
My idea was to put the items in to a special non-display category on the backend and to somehow configure SOLR to put a greater weighting on these products for the search results. But I can not see how to do this. I can only see how to weight product attributes.
Anyone have any suggestiogs?
Giving fields different weights is very simple in Solr -- simply add the following to your default requestHandler in solrconfig.xml
<requestHandler name="/select" class="solr.SearchHandler">
<lst name="defaults">
...
<qf>Weighted_Category^3 Lesser_Category^0.5</qf>
</lst>
</requestHandler>
This weighs "Weighted Category" by a factor of 3, should there be a match.
Magento-solr has a built in function to do exactly this.
magento/lib/apache/solr/config/elevate.xml:
<elevate>
<query text="foo bar">
<doc id="1" />
<doc id="2" />
<doc id="3" />
</query>
<query text="ipod">
<doc id="MA147LL/A" /> <!-- put the actual ipod at the top -->
<doc id="IW-02" exclude="true" /> <!-- exclude this cable -->
</query>
</elevate>

I'm using the following XML to fetch all the contacts.
<fetch version='1.0' output-format='xml-platform' mapping='logical' distinct='true'>
<entity name='contact'>
<attribute name='fullname' />
<attribute name='emailaddress1' />
<order attribute='fullname' descending='false' />
<link-entity name='listmember' from='entityid' to='contactid' visible='false' intersect='true'>
<link-entity name='list' from='listid' to='listid' alias='aa'>
<filter type='and'>
<condition attribute='listname' operator='eq' value='myList' />
</filter>
</link-entity>
</link-entity>
</entity>
</fetch>
However, I'd like the CRM also to produce the leads (preferably in the same list). Is it doable and if so, how?
As far as I know this isn't possible.
Mscrm will return zero or more records for a single entity and zero or more records from entities linked to those in a single call.
For example your fetch above gets contacts and list members linked to contacts.
You could retrieve leads linked to your contacts in a single call, but if you want all leads you will have to perform a separate call.
Edit:
"(a) two different <entity> section in the same <fetch>" - This wont work because its not valid schema.
FetchXML Schema
entity element - used for specifying the root element for a fetch,
only
one root entity is allowed in a given fetch, all others
are dependent on this entity and are marked as
link-entity
"(b) on a super class that both contacts and leads inherit from" - This wont work because as far as I know it doesn't exist. Although a single object Entity exists that can be used to represent all records in code, I don't believe this allows querying of multiple entities at once.
