Incorrect results with lead/lag over windows with duplicates ------------------------------------------------------------ Key: TEIID-5477 URL: https://issues.jboss.org/browse/TEIID-5477 Project: Teiid Issue Type: Bug Components: Query Engine Reporter: Steven Hawkins Assignee: Steven Hawkins Fix For: 11.2, 11.1.1, 11.0.3, 10.3.5, 8.12.16.6_4 LEAD/LAG should be computed as row values functions, rather than over a range. for example: select e1, lead(e1, 2) over (order by e1 nulls last) from pm1.g1 returns three rows of ('a', 'c') - rather than the expected ('a', 'a'), ('a', 'b'), ('a', 'c')
