Building Queries

CRM 1.2

A QueryExpression is used to programmatically build a query containing data filters and search conditions that define the scope of a database search. A QueryExpression is used for single-object searches, for example, searching for all accounts that match certain search criteria. QueryExpression provides a strong typed (object based) approach to building queries that can be executed. To save a query, you can convert it to Fetch using a QueryExpressionToFetchXml request and save it as a userquery. Because QueryExpression is strongly typed, Microsoft IntelliSense support is available for the QueryExpression object within Visual Studio .NET.
