Adding way to submit query in object form using the internal Teiid language objects. This
lets user to skip the whole JDBC layer and directly submit the query to the engine and
also skips the parsing of the SQL from string form.

public ExecutionResults executeQuery(final String vdbName, final int version,
final QueryCommand command, final long timoutInMilli) throws TeiidException;

Key: TEIID-2062
URL: https://issues.jboss.org/browse/TEIID-2062
Project: Teiid
Issue Type: Enhancement
Components: Embedded
Reporter: Steven Hawkins
Assignee: Steven Hawkins
Fix For: 8.1
Teiid's federation and query processing features are of use to several other
projects. An embeddedable form is desired such that:
- the application server is not required
- queries could be issued in the engine object model to by-pass parsing/validation and
results retrieved without the need for JDBC
- new translators could be added
The following would be open for discussion:
- the inclusion of saxon/xom/nux for SQL/XML processing
- if the general deployment logic would be needed, or if just a single dynamic vdb is all
that is needed
See the org.teiid.jdbc.FakeServer in the test-integration/common module for a rough
approximation at the entry point for a embeddable server. Note that it is more geared at
unit testing JDBC/ODBC rather than providing the features needed here.
