Error joining file data sources ------------------------------- Key: TEIID-3716 URL: https://issues.jboss.org/browse/TEIID-3716 Project: Teiid Issue Type: Bug Components: Query Engine Reporter: Salvatore R Assignee: Steven Hawkins Fix For: 8.12 I have defined a file data source in the VDB and I am running a query that joins a CSV file to another relation (a relational table or a subquery like in the following example). Two different exceptions are thrown if a INNER or LEFT OUTER JOIN is used: {code:sql} SELECT csv_table.* FROM (call f1.getFiles('csvFile.csv')) f, TEXTTABLE(to_chars(f.file,'UTF-8') COLUMNS "a" STRING , "b" STRING DELIMITER ',' QUOTE '''' SKIP 1 ) csv_table LEFT JOIN (SELECT '1' as a, '2' as b) as t ON csv_table.a = t.a;
