[teiid-issues] [JBoss JIRA] (TEIID-2844) remove unauthorized columns from select *

[Steven Hawkins (JIRA)]

    [ https://issues.jboss.org/browse/TEIID-2844?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12942862#comment-12942862 ] 

Steven Hawkins commented on TEIID-2844:
---------------------------------------

Added a system property:

org.teiid.ignoreUnauthorizedAsterisk (to control the system wide default behavior - defaults to false) and a session property ignore_unauthorized_asterisk to set whether select * or a qualified asterisk will ignore unauthorized columns when expanded.

So typically a client would issue:

{code}
select teiid_session_set('ignore_unauthorized_asterisk', true)
{code}

to enable this behavior - which could be made part of the initialization if using a pool.

A couple of follow ons for this issue include - providing a high level way of enabling this feature from the client side and refining the server side logic to ensure that plans and results are cachable for authorization modified commands.

> For ease of use with entitlement checking enabled, user queries with select * and *.tbl, should simply not treat unauthorized columns as selectable.
