In Microsoft Dataverse, developers often need to retrieve summarized data (e.g., count, sum, average) instead of full record sets. While QueryExpression is designed for row-level queries, it can perform aggregate operations when configured properly.
Why Use Aggregate Queries?
Efficiently get insights like total accounts, average revenue, or max sales.
Reduces data transfer and improves performance in reports, plugins, or dashboards.
Prerequisites for Performing Aggregate Queries Using QueryExpression
- Ensure that .NET Framework version 4.6.2 or later is installed to support integration with Dynamics 365 SDK libraries.
- Include references to the following required SDK libraries:
Xrm.Sdk and Microsoft.Crm.Sdk.Proxy. - Use of QueryExpression with ColumnSet, AttributeExpressions, and proper aliasing for aggregation.
- Aggregation must be explicitly enabled by setting QueryExpression.ColumnSet and configuring QueryExpression Criteria accordingly.
