[teiid-issues] [JBoss JIRA] (TEIID-2246) Incorrect results with TIMESTAMPDIFF

Incorrect results with TIMESTAMPDIFF ------------------------------------ Key: TEIID-2246 URL: https://issues.jboss.org/browse/TEIID-2246 Project: Teiid Issue Type: Bug Components: Server Affects Versions: 7.4.4 Reporter: Van Halbert Assignee: Johnathon Lee Fix For: 8.2 Attachments: FunctionMethods.java.patch, TestFunction.java.patch 2 issues with TIMESTAMPDIFF: 1. select TIMESTAMPDIFF(SQL_TSI_DAY,parseDate('2012-01-01', 'yyyy-MM-dd'),parseDate('2304-04-12', 'yyyy-MM-dd')); result = 106751 If you increase the end date by 1 day: select TIMESTAMPDIFF(SQL_TSI_DAY,parseDate('2012-01-01', 'yyyy-MM-dd'),parseDate('2304-04-13', 'yyyy-MM-dd')) result = -106751. I would expected the answer to be 106752 2. Both MS Excel and Oracle give the number of days between 1-Jan-2012 and 12-Apr-2304 as 106752, not the 106751 that EDS is reporting.
