Inside FetchXML pt 10 – link-entity (again)

Posted On 5th April 202028th September 2020 By Mark Carringtoncomment

A follow-up on my previous post on link-entity, prompted by this tweet from Daryl LaBar: Was unaware of the new join operators. @jordimontana @XrmWizard have either of you used these, or know what they are supposed to do?

Inside FetchXML pt 7 – rowaggregate

FetchXML Multiple Links

Posted On 13th January 202028th September 2020 By Mark Carringtoncomment

One common pattern of queries I see about FetchXML is how to write queries to ask two different questions about the same related entity. For example: Invoices that include product A AND product B?
