Oracle query all_tab_columns.data_default (type LONG)

I have run this query:

SELECT
    OWNER,
    TABLE_NAME,
    COLUMN_NAME,
    DATA_TYPE,
    DATA_LENGTH,
    (CASE
        WHEN DATA_PRECISION IS NULL THEN 0
        ELSE DATA_PRECISION
     END) DATA_PRECISION,
    (CASE
        WHEN DATA_SCALE IS NULL THEN 0
        ELSE DATA_SCALE
     END) DATA_SCALE,
    NULLABLE,
    COLUMN_ID
    DEFAULT_LENGTH,
    DATA_DEFAULT,
    (CASE
        WHEN DATA_DEFAULT IS NULL THEN '0'
        ELSE DATA_DEFAULT
     END) DATA_DEFAULT1
FROM 
    all_tab_columns
WHERE 
    table_name LIKE 'TABLE1';

But it throws an error at column DATA_DEFAULT:

ORA-00932: inconsistent datatypes: expected CHAR got LONG
00932. 00000 - "inconsistent datatypes: expected %s got %s"

How can I fix that?

Thanks!
