The Query APIs allow you to retrieve data from mobile business objects, to retrieve relationship and paging data, and to retrieve and filter a query result set.
Retrieving Data from Mobile Business Objects
You can retrieve data from mobile business objects through a variety of queries including object queries, arbitrary find, and through filtering query result sets.
Retrieving Relationship Data
A relationship between two MBOs allows the parent MBO to access the associated MBO.
Paging Data
On low-memory devices, retrieving up to 30,000 records from the database may cause the custom client to fail and throw an OutOfMemoryException.
Query and Related Classes
The following classes define arbitrary search methods and filter conditions, and provide methods for combining test criteria and dynamically querying result sets.
