[teiid-issues] [JBoss JIRA] Closed: (TEIID-357) Create a cannonical set of push down functions
[
https://jira.jboss.org/jira/browse/TEIID-357?page=com.atlassian.jira.plug...
]
Steven Hawkins closed TEIID-357.
--------------------------------
Resolution: Done
Added SourceSystemFunctions, which is just a constants class. We'll revisit this a
little more if we need to offer more metadata about the functions.
Create a cannonical set of push down functions
----------------------------------------------
Key: TEIID-357
URL: https://jira.jboss.org/jira/browse/TEIID-357
Project: Teiid
Issue Type: Sub-task
Components: Connector API, Query Engine
Affects Versions: 6.0.0
Reporter: Steven Hawkins
Assignee: Steven Hawkins
Fix For: 6.0.0
Original Estimate: 1 day
Remaining Estimate: 1 day
Currently the engine may pushdown aliases of common functions (convert/cast, nvl/ifnull,
lower/lcase, etc.) duplications should be removed by the rewriter to a canonical set
defined by constants so that connector developers know what system functions to expect.
