Hi,
SET HEA[DING] {ON | OFF}
Controls printing of column headings in reports.
SQL>  select NUM_ROWS from user_tables where table_name='TABLE_A';
  NUM_ROWS
      4999
SQL> set heading off
SQL>  select NUM_ROWS from user_tables where table_name='TABLE_A';
      4999
SQL> select 'song name :' as "song",t.num_rows from dual,( select NUM_ROWS from user_tables where table_name='TABLE
_A') t;
song name :       4999
it works
SQL>  select ' song name : ' || NUM_ROWS from user_tables where table_name='TABLE_A';
'SONGNAME:'||NUM_ROWS
song name : 4999
1 row selected.
SQL> set heading off
SQL>  select ' song name : ' || NUM_ROWS from user_tables where table_name='TABLE_A';
song name : 4999
