UPDATE statement performance

Is there any better way of writing the following UPDATE statement?

DML statement:
UPDATE mytable SET obj_path = 80 WHERE obj_volumeid = 3 and obj_itemid LIKE 'A#%' AND obj_collectionid = 2 AND obj_path = 1;

Note:
1.The table has no partitions.
2.The table has >30 million rows.
3. The script has hundres of similar update statements with different values for obj_path, obj_volumeid, obj_itemid, obj_collectionid columns in mytable.

Check if you can use FORALL loop. If should be possible if the parameters you pass can be generated based on loop counter.

Yes, FORALL loop works fine.

Thanks a bunch!
