[JBoss JIRA] Created: (TEIID-669) Support "pass though" SQL commands to sources

Support "pass though" SQL commands to sources
---------------------------------------------
Key: TEIID-669
URL: https://jira.jboss.org/jira/browse/TEIID-669
Project: Teiid
Issue Type: Feature Request
Components: Query Engine
Reporter: Ramesh Reddy
Assignee: Steven Hawkins
Fix For: 6.2.0
Currently there is no mechanism in Teiid, when a query is submitted to a runtime engine that is passed through the query engine unadulterated and unmodified and submitted directly to a source connector. All queries are parsed, optimized, re-written. Some times this limits the functionality in Teiid, when a user would like to execute a query that is very "source" specific. For example Oracle supports lots of Oracle specific functions that are not supported by the SQL spec, to support execution of these in Teiid user need to resort to UDF, which is cumbersome and involves modelling.
Another benefit of this is also to pass DDL to sources, currently since Teiid does not support DDL, this is not possible at all.
There is no-expectation that these queries are part of any data integration, these are one off queries that enhance user experience with Teiid if they use this feature. Command Payload mechanism is similar system that is used for authentication and authorization needs at the connector level, this feature can use similar techniques or use some custom extension to the language to define a query etc.

[JBoss JIRA] Created: (TEIID-1241) Create a WSDL based WS Resource Adapter
by Steven Hawkins (JIRA)
Create a WSDL based WS Resource Adapter
---------------------------------------
Key: TEIID-1241
URL: https://jira.jboss.org/browse/TEIID-1241
Project: Teiid
Issue Type: Feature Request
Components: Misc. Connectors
Affects Versions: 7.2
Reporter: Steven Hawkins
Assignee: Steven Hawkins
Fix For: 7.2
The current WS resource adapter was designed for low-level usage, which doesn't even consult a WSDL. It would be good though to update the existing adapter (or introduce a new) to utilize a WSDL. The WSDL would be used to expose the operations through connector metadata, so that the translator could create the corresponding procedures model.service.port.binding.operation(arg...). Import options could be used to limit the import to only particular services/ports.
The WSDL based approach would also allow for the CXF configuration to apply to more than a single port and to more easily allow the policy definition for WS security.
Additional semantic support for RPC could be considered, but would need to use JAX-RPC

Document/expand sequence support
--------------------------------
Key: TEIID-1131
URL: https://jira.jboss.org/browse/TEIID-1131
Project: Teiid
Issue Type: Feature Request
Components: JDBC Connector, Query Engine
Affects Versions: 7.0
Reporter: Steve Hawkins
Assignee: Steve Hawkins
Fix For: 7.1
Currently sequence workaround logic only exists for oracle and is undocumented. We should look at expanding sequence support - even for dynamic vdbs, see SQuriel's handling of system queries for retrieving sequence metadata.
At least allowing the workaround logic to work for all sources that support sequences (Postgres, DB2, etc.) would be good.

Clob usability
--------------
Key: TEIID-1248
URL: https://jira.jboss.org/browse/TEIID-1248
Project: Teiid
Issue Type: Feature Request
Components: Query Engine
Affects Versions: 8.0
Reporter: Steven Hawkins
Assignee: Steven Hawkins
Priority: Minor
Fix For: 8.0
In many circumstances, clobs should be treated as charsequences to allow for use in string functions (concat returning clob, insert, left, etc.).
There have also been customer requests to treat clobs as comparable, but that there are a lot of places including at design time where we validate against clobs being comparable that it may not be a good idea.
