[teiid-issues] [JBoss JIRA] Resolved: (TEIID-252) Add constant cohersion to rewriter for comparison criteria.

Add constant cohersion to rewriter for comparison criteria. ----------------------------------------------------------- Key: TEIID-252 URL: https://jira.jboss.org/jira/browse/TEIID-252 Project: Teiid Issue Type: Feature Request Components: Query Engine Affects Versions: 6.0.0 Reporter: Steven Hawkins Assignee: Steven Hawkins Priority: Minor Fix For: 6.1.0 Original Estimate: 4 hours Remaining Estimate: 4 hours From a recent discussion with Larry, it would be good for the rewriter to handle situations like: "convert(col, type1) = constant of type2" => "col = constant of type1", where type1 is something other than string. We already have resolver logic to do this and in many circumstance failing to apply the narroring conversion would indicate a failing comparison.
