2.1.14.1.2 Content Streams
Content streams are NOT exposed through this relational view.
2.1.14.1.3 Result Set
When a query is submitted, a set of pseudo CMIS objects will be returned. These pseudo objects are
comprised of the properties specified in the select clause of the query statement.
For each property in each object in the result set, the repository MUST include the property definition id as
well as either the query name (if no alias is used) or the alias in place of the query name (if an alias is used).
If the select clause of the query statement contains properties from a single type reference then the repository
MAY represent these pseudo-objects with additional object information.
2.1.14.2 Query Language Definition
This query languages is based on a subset of the SQL-92 grammar. CMIS-specific language extensions to
SQL-92 are called out explicitly.
The basic structure of a CMIS query is a SQL statement that MUST include the following clauses:
SELECT [virtual columns list] This clause identifies the set of virtual columns that will be included in the
query results for each row and optionally their aliases.
