When I try to execute the belwo query i am getting the below error

ORA-01427: single-row subquery returns more than one row

Is any other way to re-write the below query.

SELECT *
  FROM all_source
 WHERE LOWER(text) LIKE
         (SELECT '''' || '%' || LOWER(table_name) || '%' || ''''
            FROM dba_tables
           WHERE owner = 'CRIS_WAREHOUSE_USER')

Do not use a subquery, join the "tables".

Yes, sorry, I wrote too fast what I meant but it would not happen if you told us what you want to do instead we have to reverse engineer it.
So what is your purpose EXACTLY.

The join is not directly on the views columns but on your (LIKE) test.
