Call complex type oracle procedures

Question

Hello!
My task is to call some stored procedures from Oracle. These procs developed by other guy.
The trouble is that some of the OUT parameters are TABLE or VARRAY of OBJECT types.
Here is example of procedure:<br>
<br>
<br>
type tag_event_varray as varray(100) of tag_event_object
...<br><br>
TYPE tag_event_object AS object(
tag_event_id NUMBER,
tag_id number......
......<br>
<br>
PROCEDURE get_tag_events(p_customer_id in number, <br>
p_site_id in number,
p_tag_event_varray out tag_event_varray,
p_feedback_varray out feedback_varray); <br><br>
------------------------------------------------------------------<br><br>
All documentation I found on the web is about fetching either REF CURSOR or VARRAY of simple elements like number...<br><br>
I have tried this:<br><br>
// connection do DB <br>
<br>
$s = OCIParse($c, "begin get_tag_events(:bind1, :bind2,:bind3, :bind4); end;");<br>
$coll = OCINewCollection($c, "TAG_EVENT_VARRAY");<br>
.........<br>
OCIBindByName($s, ":bind3", $coll, -1, OCI_B_SQLT_NTY); <br>
OCIExecute($s, OCI_DEFAULT);<br>
for ($i = 0; $i < $coll->size(); $i++) {<br>
$id = $coll->getElem($i);<br>
echo "Id: $id<br>";<br>
} <br>
----------------------------------------------------------<br>
$coll->size() gives the right size of collection, but getElem() is empty.<br>
Any suggestions?<br>
Help is very appreciated

It appears that you're trying to manage a VARRAY collection of a user-defined object type. If that's true, then my understanding is that it shouldn't work with the current OCI8 libraries. OCI8 only supports collections of scalar data types, like NUMBER, DATE, et cetera.
You can change the PL/SQL code to return a parallel set of scalar collections and then the PHP logic flow you're using will work.
Hope this helps, Michael.
