Query Service

You can issue a query for data without using an AIF document service or
creating a custom service. The query service returns data in a dataset and
implements a paging mechanism so that you can manage queries that return large
amounts of data. When you call the query service, you can specify the query to
run in one of three ways:

• Static query: A query that is already defined in the Application
Object Tree (AOT) under the Queries node.

• User-defined query: A query that is defined by using the
QueryMetadata class which is found in the metadata service.

• Dynamic query: A query that is defined in an X++ class that
extends the AIFQueryBuilder class. All query logic is contained in
the query builder class.
