Like pushdown handling
----------------------
Key: TEIID-586
URL: https://jira.jboss.org/jira/browse/TEIID-586
Project: Teiid
Issue Type: Bug
Components: LDAP Connector, Query Engine, Salesforce Connector
Affects Versions: 6.0.0
Reporter: Steven Hawkins
Assignee: Steven Hawkins
Priority: Minor
Fix For: 6.2.0
Both salesforce and ldap like semantics are not the same as SQL. …
[View More]We could capture this with more capabilities supportsLikeCaseSensitive and supportsLikeWildcardSingleCharacter repectively, or another approach would be to allow the connector to generically indicate partial support and have the query engine both push down the conjunct and leave a copy to be applied after the query. With either explicit supports or generic partial support it would only applicable to top level where clause conjuncts.

[JBoss JIRA] Created: (TEIID-587) Better pushdown support for exotic joins

Better pushdown support for exotic joins
----------------------------------------
Key: TEIID-587
URL: https://jira.jboss.org/jira/browse/TEIID-587
Project: Teiid
Issue Type: Feature Request
Components: Query Engine
Affects Versions: 6.1.0
Reporter: Steven Hawkins
Assignee: Steven Hawkins
Fix For: 6.2.0
Our optimizations get in the way of Salesforce pushdown. Specifically rewriting like …
[View More]when possible to = and converting outer joins to inner joins. In both cases we would need to not perform the optimization in the first place or convert into an acceptable form prior to pushdown.
The next is that salesforce, while requiring key criteria also allows other criteria in the left outer join on clause (which would be the same as having criteria on the nested relationship query in the salesforce query). With the capabilities as currently defined this would cause the query to not be pushed down. We should consider adding a relational supported join criteria type that requires key criteria but allows for outside criteria. Also we should treat the lack of inner join support to mean that criteria on the inner side of an outer join cannot be pushed.

Quick Start Guide / Examples needs to add derbyclient.jar to UDFs for previewing
--------------------------------------------------------------------------------
Key: TEIID-358
URL: https://jira.jboss.org/jira/browse/TEIID-358
Project: Teiid
Issue Type: Bug
Components: Documentation
Affects Versions: 6.0.0
Environment: fedora 10
Reporter: Paul Nittel
Assignee: Steven Hawkins
I ran into …
[View More]this while assisting user Bribek.
When the Derby source is created and imported, a connector binding is built in the Designer. The one thing Designer does not do is place the jar file where it needs to be for previewing. The Quick Start Example needs to add the step of adding the derbyclient.jar file using the UDFs view and "Import UDF Extension Jar Files" action.
IMHO, the Quick Start needs to be revisited to determine exactly what the required minimum effort is for a user to get through this. Perhaps on the Teiid side avoid all modeling and add a Quick Start on the Designer side that builds the VDB. If Teiid can do the Quick Start with just a VDB, that might be preferable.
