Summary: Error joining file data sources
Key: TEIID-3716
URL: https://issues.jboss.org/browse/TEIID-3716
Project: Teiid
Issue Type: Bug
Reporter: Salvatore R
Assignee: Steven Hawkins
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;
{code}
{code:sql}

It seems that the structure of the CSV file is not relevant since this issue can be reproduced even providing a file that does not exist.
