Query giving wrong output

Question

I am trying to look for sub programs that use the synonyms in the schema.I wrote the following query.But its giving strange output.
  select usy.synonym_name, us.text, us.name, us.type
  from user_synonyms usy, user_source us
where upper(us.text) like ('%' || usy.synonym_name || '%')
   and usy.synonym_name in
       (select synonym_name
          from user_synonyms us
         where us.synonym_name <> us.table_name
           and table_owner = 'XYZ')
order by usy.synonym_nameOutput
synonym_name text
txn_deposit select pir_detail_txn.instrument_amnt
I wonder why txn.instrument is taken same as txn_instrument which is the synonym name??

Answer 1

where name like 'txn_instrument'
give all outputs like
txn_instrument
txn.instrument
txn1instrument
txn2instrument .......
but
where name like 'txn\_instrument' escape '\'
gives only txn_instrument
