Oracle Explorer/Retrieve Data on Views

Question

does not work because of selecting the ROWID column. view uses piplined function :
SELECT "OBJECT_TYPE","OBJECT_OWNER","OBJECT_NAME","OBJECT_DDL_TIME","OBJECT_ID" FROM TABLE ( PF_GET_OBJECT_DESC('TABLES'))

hi
here is the code of the piplined function :
CREATE OR REPLACE FUNCTION pf_get_object_desc(object_name IN VARCHAR2)
RETURN to_dbobj_rec_coll
PIPELINED AS
l_dbobj to_dbobj_rec := to_dbobj_rec(SYSDATE,
NULL,
NULL,
NULL,
NULL);
BEGIN
-- Suche in tables
FOR l_row IN (SELECT SYSDATE AS odate,
rownum AS OID,
table_name AS oname,
owner,
'TABLE' AS typ
FROM dba_tables
WHERE table_name LIKE '%' || object_name || '%') LOOP
NULL;
l_dbobj.object_ddl_time := l_row.odate;
l_dbobj.object_id := l_row.OID;
l_dbobj.object_name := l_row.oname;
l_dbobj.object_owner := l_row.owner;
l_dbobj.object_type := l_row.typ;
PIPE ROW(l_dbobj);
END LOOP;
-- Suche in views
FOR l_row IN (SELECT SYSDATE AS odate,
rownum AS "OID",
view_name AS oname,
owner,
'VIEW' AS typ
FROM dba_views
WHERE view_name LIKE '%' || object_name || '%') LOOP
NULL;
l_dbobj.object_ddl_time := l_row.odate;
l_dbobj.object_id := l_row.OID;
l_dbobj.object_name := l_row.oname;
l_dbobj.object_owner := l_row.owner;
l_dbobj.object_type := l_row.typ;
PIPE ROW(l_dbobj);
END LOOP;
RETURN;
END pf_get_object_desc;
You cannot use the proceudre dirctly in visual studio,
retrun types of obect collections are not supported - yet.
so you create a view :
CREATE OR REPLACE VIEW VW_GET_OBJECT_DESC AS
SELECT "OBJECT_TYPE",
"OBJECT_OWNER",
"OBJECT_NAME",
"OBJECT_DDL_TIME",
"OBJECT_ID"
FROM TABLE(pf_get_object_desc('TABLES')) WITH READ ONLY
Now the problem in Oracle explorer is that on retreive data the ROWID -Colum is selected too -but could never be provided in a pipelined result set.
Regards Carl
so selecting views should be done with read only datasets?
