Subject: Re: [eclipselink-users] StoredFunctionCall with IN List parameter
Hey Michele,
The following should work for the simple case you mention below. Note that when adding the named argument to the call you'll want to also include the SQL type (2003 for
ARRAY) and the name of your nested table ("USERS_ID_LIST_TYPE"). Also, I would typically add the input parameter values to the query
as opposed to the call. You have the option of passing in a List of argument values when you execute the query if you'd rather not modify the query directly (see public Object executeQuery(DatabaseQuery
query, List argumentValues) on
Session).
StoredFunctionCall call = new StoredFunctionCall();
call.setProcedureName("EDMRDBA.USERS_PKG.GET_USERS_NAME_TEST");
call.addNamedArgument("in_users_id_list", "in_users_id_list", 2003, "USERS_ID_LIST_TYPE");
ValueReadQuery query = new ValueReadQuery();
query.setCall(call);
query.addArgument("in_users_id_list", java.sql.Array.class);
List<Integer> userIds = new ArrayList<Integer>();
userIds.add(1);
userIds.add(2); userIds.add(3);
query.addArgumentValue(userIds);
...
Hopefully this will get you going.
Cheers,
Dave

Hi there,
I need help with a stored function. I can get the same function to work if I send in a string as the input parameter. However, I can’t seem to get the syntax correct
for sending in a List of string and returning a cursor. I keep getting the error message of invalid column type.
System Information:
Tomcat 6.0; jdk 1.6; maven project; eclipselink 2.3.0; javax.persistence-2.0.3; database Oracle 10g; oracle driver: ojdbc6-11.1.0.7.0; NetBeans
7.1.2 IDE
Here is the code etc. for just sending in the List (I’ll deal with the cursor later):
Error message:

Query: ValueReadQuery()
Method setting up the query:
public String getUsersNameListByUserIds(List<String> userIdsList)
{
EntityManager em = null;
EntityTransaction txn;
org.eclipse.persistence.jpa.JpaEntityManager emJPA = null;
String usersname = "";
try
{
em = super.getEntityManager();
emJPA = org.eclipse.persistence.jpa.JpaHelper.getEntityManager(em);
txn = emJPA.getTransaction();
StoredFunctionCall call = new StoredFunctionCall();
call.setProcedureName("EDMRDBA.USERS_PKG.GET_USERS_NAME_TEST");
// Only in parameters (not results) are added using the .addNamedArgument method
call.addNamedArgumentValue("in_users_id_list", userIdsList);
// The next method is required when you're calling
// a stored function.
call.setResult("out_usersname", String.class);
ValueReadQuery query = new ValueReadQuery();
query.setCall(call);
query.addArgument("in_users_id_list");
usersname = (String) emJPA.getActiveSession().executeQuery(query);
}
catch (RuntimeException e)
{
System.out.println("inside exception: " + e.getMessage());
logger.debug("Exception caught in: " + this.getClass().getName() + " Error: " + e.getMessage());
}
finally
{
if (em.isOpen() || em != null)
{
em.close();
}
}
return usersname;
Database scripts:
CREATE OR REPLACE PACKAGE EDMRDBA.USERS_PKG AS
// Type that will be returned by the cursor
TYPE USERSNAME_REC IS RECORD (
USERSID VARCHAR2(20),
USERSNAME VARCHAR2(100)
);
// cursor to be returned when I get the cursor portion working
TYPE CURSOR_TYPE IS REF CURSOR;
FUNCTION GET_USERS_NAME_test(in_users_id_list IN USERS_ID_LIST_TYPE) RETURN VARCHAR2;
END USERS_PKG;
CREATE OR REPLACE PACKAGE BODY EDMRDBA.USERS_PKG AS
FUNCTION GET_USERS_NAME_TEST(in_users_id_list IN users_id_list_type) RETURN VARCHAR2 AS
out_usersname VARCHAR2(255);
BEGIN
SELECT
userid INTO out_usersname--,
FROM users
WHERE userid IN (SELECT COLUMN_VALUE FROM TABLE(in_users_id_list));
RETURN('test');
END;
END USERS_PKG;
CREATE OR REPLACE TYPE EDMRDBA.USERS_ID_LIST_TYPE
AS TABLE OF varchar2(8);
What am I missing or have wrong? Please help!
When I add a cursor as the return value, would I need to use a PLSQLNamedStoredFunction since the cursor will be of the following type?
CREATE OR REPLACE TYPE EDMRDBA.O_USERSNAME_TYPE AS OBJECT (
USERSID VARCHAR2(20),
USERSNAME VARCHAR2(100)
CREATE OR REPLACE TYPE EDMRDBA.USERS_NAME_TYPE
AS TABLE OF O_USERSNAME_TYPE
Any help would be greatly appreciated.
