My goal was to return result set from stored procedure using Teiid on Oracle. This should be only possible by stored function.
I created stored function in the DB
The stored function
create or replace FUNCTION getEmployeeSurnames RETURN sys_refcursor AS resultset sys_refcursor; BEGIN OPEN RESULTSET FOR SELECT surname FROM employees; RETURN RESULTSET; END;
In Teiid designer I imported the function (VDB in attachment). After deploying the VDB I tried to call the function
JDBC query
List<String> surnameList = new ArrayList<String>(); String[] connectionProps = useCache ? new String[] {"resultSetCacheMode=true"} : new String[] {}; String query = "{CALL getEmployeeSurnames()}"; Connection conn = getTeiidConnection(VDBNAME, connectionProps); Statement cs = conn.createStatement(); cs.execute(query); ResultSet rs = cs.executeQuery(query); while (rs.next()) { surnameList.add(rs.getString(1)); } conn.close();
The exception on the server is
server.log

This is solely problem on Oracle. I tried tested stored procedures/functions that return resultsets on other DB engines without problems (Postgres, MSSQL, MySQL, DB2).
Additional info. In SOA platform there is native oracle driver:
