[teiid-issues] [JBoss JIRA] Closed: (TEIID-1009) BQT Pushdown query "ORDER BY" is not always ordering results properly

BQT Pushdown query "ORDER BY" is not always ordering results properly --------------------------------------------------------------------- Key: TEIID-1009 URL: https://jira.jboss.org/browse/TEIID-1009 Project: Teiid Issue Type: Bug Components: Query Engine Affects Versions: 7.0 Reporter: Warren Gibson Assignee: Steven Hawkins Fix For: 7.0 Pushdown queries with "ORDER BY" are not always returning results in correct order. The below query is returning query results in the wrong order for Pushdown on DB2, MySql, Ora9-10-11, and SqlServer sources. If BQT1.SmallA.StringKey is placed in the SELECT clause the results are returned in the correct order. SELECT BQT1.SmallA.IntNum, BQT2.SmallB.StringNum FROM BQT1.SmallA, BQT2.SmallB WHERE BQT1.SmallA.IntNum = BQT2.SmallB.StringNum AND BQT1.SmallA.IntKey >= 5 AND BQT2.SmallB.IntKey >= 5 ORDER BY BQT1.SmallA.StringKey
