Experts,

Please, help me in doing that. I am trying to generate a sql script that
will give me all the default values for the columns in my datatypes. My problem
is that DATA_DEFAULT column in DBA_TAB_COLUMNS table has LONG datatype. Please,
help me to get those values. Look below and you will understand what i am
doing.

select
'alter table ' || owner || '.'|| table_name || ' modify '|| '( ' || column_name
|| ' default ' || data_default || ' ) ' || ' ;'
from dba_tab_columns
where owner not in ('SYS', 'SYSTEM', 'SYSMAN', 'OUTLN', 'WMSYS', 'DBSNMP')
and owner not like '%SYS%'
and data_default is not null;

ORA-00932
ORA-00932: inconsistent datatypes: expected number got long
