Steven Hawkins resolved TEIID-1786.
-----------------------------------
Resolution: Duplicate Issue
This is a dup of TEIID-832. This has always been the case with Oracle native (datadirect
supports this case without any special effort). This is a KI and I don't believe
should be a blocker.
Cannot invoke stored function that returns resultset on Oracle
---------------------------------------------------------------
Key: TEIID-1786
URL:
https://issues.jboss.org/browse/TEIID-1786
Project: Teiid
Issue Type: Bug
Components: JDBC Connector
Affects Versions: 7.4.1
Reporter: Filip Nguyen
Assignee: Steven Hawkins
Priority: Blocker
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
{code:title=The stored function|borderStyle=solid}
create or replace FUNCTION getEmployeeSurnames RETURN sys_refcursor AS
resultset sys_refcursor;
BEGIN
OPEN RESULTSET FOR SELECT surname FROM employees;
RETURN RESULTSET;
END;
{code}
In Teiid designer I imported the function (VDB in attachment). After deploying the VDB I
tried to call the function
{code:title=JDBC query|borderStyle=solid}
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();
{code}
The exception on the server is
{code:title=server.log|borderStyle=solid}

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:
