ViewObject Query

Question

Hi,
Could you please tell me what is the wrong with my Query?
SELECT v.txh_id, i.ID item_id,null pack_id, i.NAME item_name, null pack_unit, NULL pack_size, v.QUANTITY Quantity
FROM items i, txn_headers t, inv_txns v
WHERE t.ID = v.txh_id AND v.itm_id = i.ID AND v.txh_id = ?
UNION
SELECT v.txh_id, null item_id, p.ID pack_Id, null item_name, p.unit pack_unit, p.pack_size_in_units_of_use pack_size, v.QUANTITY Quantity
FROM packagings p, txn_headers t, inv_txns v
WHERE t.ID = v.txh_id AND v.pkg_id = p.ID AND v.txh_id = ?
it is throwing SQL exception while I am setting those Paramenters like viewObj.setWhereClauseParams(Obj[]) programmatically.
Please help me...
Thanks in advance.
Bala.

What specific error message do u get?
Does it help if you use something like:
WHERE t.ID = v.txh_id AND v.itm_id = i.ID AND v.txh_id = :p_1
instead of "?" ?
