The difference between statement1 and statement 2 is that statement 2 requests 
the data for one specific client_code and oracle can use an index 
me_client_assets to quickly hone in on that particular client.

Statement 1 has no such limiting predicate and therefore Oracle can not use an 
index. If it can't use an index the only other option is a FTS.
