Dynamic data integration feature (Integrate data with out a VDB)
----------------------------------------------------------------
Key: TEIID-684
URL: https://jira.jboss.org/jira/browse/TEIID-684
Project: Teiid
Issue Type: Feature Request
Components: Connector API, Query Engine
Reporter: Ramesh Reddy
Assignee: Steven Hawkins
Priority: Critical
Fix For: 6.3.0
This is feature request for dynamically integrating the data with out any modelling exercise, so that any tooling is not required before you can start integrating data.
Using this feature, the user would create/define a Connectors (data sources) in the Teiid runtime engine, and then user connects to runtime engine using the JDBC driver provided, then he/she can start writing SQL queries that spans multiple data sources in a single statement as if they are single source.
For example:
Data Source: A has
TableA1
TableA2
DataSource: B has
TableB1
TableB2
user can write SQL queries such as
SELECT A.TableA1.e1, A.TableA1.e2, B.TableB1.e1, B.TableB1.e2 FROM A.TableA1, B.TableB1 WHERE A.TableA1.e1 = B.TableB1.e1
They can much more complex join queries than above too.

[JBoss JIRA] Created: (TEIID-787) Merge Oracle Spatial Connector functionality into Oracle Connector
by Larry O'Leary (JIRA)
Merge Oracle Spatial Connector functionality into Oracle Connector
------------------------------------------------------------------
Key: TEIID-787
URL: https://jira.jboss.org/jira/browse/TEIID-787
Project: Teiid
Issue Type: Task
Components: JDBC Connector
Affects Versions: 6.2.0
Reporter: Larry O'Leary
Assignee: Steven Hawkins
It seems that the Oracle Spatial Connector is an extension of the Oracle Connector. Because it is an extension and the functionality, translators, capabilities, etc, are the same it means we need to manage the same connector in two different places not to mention have the same dependencies required and offered by two different packages.
Because of this duplication, I recommend that the Oracle Spatial Connector be merged with the Oracle Connector. This should be as simple as merging the supported functions defined by the Oracle Spatial Connector with the Oracle Connector and migrating Oracle Spatial specific unit tests.
Because the functions offered by the Oracle Spatial Connector are not system functions, the function definition for the Oracle Spatial functions should be kept separate and offered to the user as a post installation task if they choose to use spatial functions.
For example, if a user decides to use Oracle as a data source, they would choose the Oracle Connector regardless of whether or not they planned on using spatial functions. The connector binding configuration would be the same in either case. If the user requires the use of the spatial functions, the only post-installation/configuration step would be to install the Oracle Spatial Function Definitions into their Teiid run-time environment or into Teiid Designer to make them available at design-time.

[JBoss JIRA] Created: (TEIID-755) Oracle Connector is not honouring metadata when rewriting ORDER BY clause
by Larry O'Leary (JIRA)
Oracle Connector is not honouring metadata when rewriting ORDER BY clause
-------------------------------------------------------------------------
Key: TEIID-755
URL: https://jira.jboss.org/jira/browse/TEIID-755
Project: Teiid
Issue Type: Bug
Components: JDBC Connector
Affects Versions: 6.1.0, 6.0.0, 6.2.0
Reporter: Larry O'Leary
Assignee: Steven Hawkins
Priority: Minor
Fix For: 6.2.0
When executing a query that contains an ORDER BY clause, the Oracle Connector is rewriting the query using the column name given by the MM query rather than the source name as specified in the source model. What this means is that column name case is not being enforced.
For example:
MM User Command:
SELECT INTKEY FROM BQT1.SMALLA UNION SELECT INTKEY FROM BQT1.SMALLB ORDER BY INTKEY
Model represents INTKEY as IntKey for source name. Currently we rewrite as:
SELECT SmallA.IntKey FROM SmallA UNION SELECT SmallB.IntKey FROM SmallB ORDER BY INTKEY
This should actually be:
SELECT SmallA.IntKey FROM SmallA UNION SELECT SmallB.IntKey FROM SmallB ORDER BY IntKey
Although this does not trigger a failure with the current implementation, if the column names were qualified is SQL identifiers, the query would fail as Oracle is expecting a column name of "IntKey" and would not know what "INTKEY" was.

Backwards scrolling defect
--------------------------
Key: TEIID-775
URL: https://jira.jboss.org/jira/browse/TEIID-775
Project: Teiid
Issue Type: Bug
Components: JDBC Driver
Affects Versions: 6.0.0
Reporter: Steven Hawkins
Assignee: Steven Hawkins
Fix For: 6.2.0
Iterating backwards does not work the since RequestWorkItem is setup to expect the end row as greater than the start row. It would be much simpler if the client were changed to issue the batch bounds with the lower value as the begin row.
Clients may not have noticed this issue since they would have to do iteration beyond the third batch and then go backwards three batches.
