             Summary: Update to updatable internal materialized view should update the materialized view as well as the database
                 Key: TEIID-3952
                 URL: https://issues.jboss.org/browse/TEIID-3952
             Project: Teiid
          Issue Type: Enhancement
          Components: VDB
    Affects Versions: 8.7
         Environment: Red Hat JBoss Data Virtualization 6.2 based on Teiid 8.7.x
            Reporter: Andy Yuen
            Assignee: Barry LaFond


Updating an updatable internal materized view updates the database but not the materialized view at present. The requested enhancement is that they, both, should be updated.

Setup
Client - SquirrelSQL to access JDV
JDV 6.2 - with an updatable nternal materialized view of one table from the data source
Data Source - just one data source: MySQL

I can see from the console that the target table/view has been materialized
Then I did the following:
1) select a row from the materialized table
2) update a field in a row in the materialized view
3) select that row (value unchanged ie, same as int 1) - tried multiple times
4) issue EXEC SYSADMIN.refreshMatViewRow(...) using primary key for the row that has been changed
5) select that row (value unchanged) - now I can see the changed data

This behaviour is counter-intuitive because I was expecting that since it is an updatable materialized view, my change will write through the materialized view ie, change both the materialized view as well as the database. But in this case, it changed the database and not the materialized view?
