Using the Query Service 9
You can use the vCloud API query service to query the vCloud Director database for information about
objects in the cloud.
The query service provides the following kinds of queries:
n
Typed queries, which require you to construct a query URL that specifies a query type and optional
parameters.
n
Packaged queries, which have well-known URLs and can accept many of the same parameters used
with typed queries.
Both typed and packaged queries allow you to specify one of the following formats in which to display the
result set:
n
A records format that returns name=value pairs for all properties of each matching object. This is the
default. A name can be either a static or dynamic. Static names are predefined object property names,
and are returned in an object-specific QueryRecordResultType element. For a list of these names, see the
Queries reference pages in the vCloud API Schema Reference. Dynamic names are user-defined metadata
key names. Dynamic name=value pairs are not returned unless the object includes a non-empty Metadata
element. See Chapter 8, “Working With Object Metadata,” on page 281.
n
An idrecords format that is identical to the records format, except that object reference values are
returned in id format rather than href format. See “Objects, References, and Representations,” on
page 12.
n
A references format that returns a reference in href format to each object that matches the query
criteria.
Query results are paginated, and include links to previous and next pages where needed. Page size can be
specified in the query request. Default and maximum page sizes are specified in the vCloud Director
configuration. You can also apply filter criteria to the list of items returned.
