[teiid-issues] [JBoss JIRA] (TEIID-1869) Simple capabilities with PostgreSQL 8.3 using decodeinteger causes comm failure

Simple capabilities with PostgreSQL 8.3 using decodeinteger causes comm failure ------------------------------------------------------------------------------- Key: TEIID-1869 URL: https://issues.jboss.org/browse/TEIID-1869 Project: Teiid Issue Type: Bug Components: Query Engine Affects Versions: 7.6 Reporter: Paul Nittel Assignee: Steven Hawkins Fix For: 7.6.1, 8.0 Attachments: QT_PostgreSQL83.vdb We use PostgreSQL 8.3 twice: once to test push-down to the source and the other to test not-pushed-down queries. The following works fine with the push-down. It's not so good when we use simple-capabilities. The query is: SELECT IntKey, BooleanValue, DECODEINTEGER(BooleanValue, 'false,3,true,7') AS Decoded FROM BQT1.SmallA ORDER BY IntKey What happens is: $ ./RunQT jdbc:teiid:QT_PostgreSQL83@mm://localhost:31000 user user yes "SELECT IntKey, BooleanValue, DECODEINTEGER(BooleanValue, 'false,3,true,7') AS Decoded FROM BQT1.SmallA ORDER BY IntKey" Caught SQLException: [SingleInstanceCommunicationException] 1 [EOFException] In the case of query testing, all subsequent queries fail due to a closed socket error. Dev indicated "That's a bug with the rewriter. We are just converting the decode function into a searched case statement, but are leaving the then values as string - rather than converting them to integers. The pushdown works because the resulting string value is converted to an integer via the translator/driver logic."
