[Steven Hawkins (JIRA)]

     [ https://issues.jboss.org/browse/TEIID-4566?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Steven Hawkins updated TEIID-4566:
----------------------------------
    Description: 
With a view that has a column name that does not match the output name such as:

create foreign table x (a string, b string, c integer, primary key (a, b)) options (updatable true); create view SvcView (RowId integer PRIMARY KEY, code string, name string) as select c as rowid, a, b from x limit 2;

A query that orders over the rowid:

select rowid, code, name from svcview order by rowid limit 1

Will fail with an assertion error initializing the top level sort node.

  was:
With a view such as:

create foreign table x (a string, b string, c integer, primary key (a, b)) options (updatable true); create view SvcView (RowId integer PRIMARY KEY, code string, name string) as select row_number() over (order by a) as rowid, a, b from x;

A query that orders over the window function:

select rowid, code, name from svcview order by rowid limit 1

Will fail with an assertion error initializing the top level sort node.

        Summary: Ordered limit against preserved view fails  (was: Ordered limit against view with window function fails)
