Recursive Query Common Table Expressions (CTE) PostgreSQL --------------------------------------------------------- Key: TEIID-5731 URL: https://issues.jboss.org/browse/TEIID-5731 Project: Teiid Issue Type: Bug Components: JDBC Driver Affects Versions: 12.1.1 Environment: Ubuntu Linux 18.04 DBeaver 5.3.3 TEIID JDBC 12.1.1 Reporter: Kolmar Vasconcelos Assignee: Steven Hawkins Priority: Critical I'm trying to a recursive Common Table Expressions on my organization's VBL. I know it runs on top of PostgreSQL. I'm not responsible for the implementation, I'm just trying to access the data for Data Analysis. When I try to create the Recursive Query it gives me the error: Remote org.postgresql.util.PSQLException: ERROR: recursive query "cte" column 6 has type character varying(255) in non-recursive term but type character varying overall. The problem is with the Null value. I can't CAST Null to VARCHAR.
