[Steven Hawkins (Commented) (JIRA)]

    [ https://issues.jboss.org/browse/TEIID-1822?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12646065#comment-12646065 ] 

Steven Hawkins commented on TEIID-1822:
---------------------------------------

In light of discussions on http://community.jboss.org/thread/174886, is a global table still needed?  Or does TEIID-196 become the dominant issue?

> I'd like to be able to query a dynamically defined materialized view.  For example, suppose I issue the query
>    /* mat-view */ SELECT * FROM blah WHERE x='abc'
> Optionally (probably based on a hint), I'd like the following query to execute against the data set returned by the previous query rather than going back to the data source:
>    /* use-mat-view */ SELECT * FROM (SELECT * FROM blah WHERE x='abc') GROUP BY a
> To make this truly useful, I'd like to define indexes.  Something like:
>    /* mat-view(index-on:a,b,c) */ SELECT * FROM blah WHERE x='abc'
