I am querying using FetchXML using javascript but wondering if I want to improve the speed and execution time should I state which attributes to return? For instance, in most cases I do the following:
<fetch version="1.0" output-format="xml-platform" mapping="logical" distinct="false">
<entity name="new_account">
<order attribute="new_name" descending="false" />
<filter type="and">
<condition attribute="new_opportunity" operator="eq" uiname="New Opportunity" uitype="opportunity" value="{3CBC481F-C563-E311-AA3E-D89D676400F8}" />
</filter>
</entity>
</fetch>
But, I have been advised to do it like this:
<fetch version="1.0" output-format="xml-platform" mapping="logical" distinct="false">
<entity name="new_account">
<attribute name="new_accountid" />
<attribute name="new_name" />
<attribute name="createdon" />
<order attribute="new_name" descending="false" />
<filter type="and">
<condition attribute="new_opportunity" operator="eq" uiname="New Opportunity" uitype="opportunity" value="{3CBC481F-C563-E311-AA3E-D89D676400F8}" />
</filter>
</entity>
</fetch>
I am told that this causes only certain fields to be returned and not the entire recordset.
If anyone can advice I would be grateful.
