DECLARE
   match_count       INTEGER;
-- Type the owner/schema of the tables you are looking at
   v_owner           VARCHAR2 (255) := 'SCOTT';
-- Type the data type you are look at (in CAPITAL)
-- VARCHAR2, NUMBER, etc.
   v_data_type       VARCHAR2 (255) := 'VARCHAR2';
-- Type the string you are looking at
   v_search_string   VARCHAR2 (255) := 'KING';
BEGIN
   FOR t IN (SELECT table_name, column_name
               FROM all_tab_cols
              WHERE owner = v_owner AND data_type = v_data_type)
   LOOP
      EXECUTE IMMEDIATE    'SELECT COUNT(*) FROM '
                        || v_owner
                        || '.'
                        || t.table_name
                        || ' WHERE '
                        || t.column_name
                        || ' = :1'
                   INTO match_count
                  USING v_search_string;
      IF match_count > 0
      THEN
         DBMS_OUTPUT.put_line (   t.table_name
                               || ' '
                               || t.column_name
                               || ' '
                               || match_count
      END IF;
   END LOOP;
END;Checked and no issues in Toad too...
