Hi,
Excute following script for each of the Schema & then run import as per your requirement.
set heading off
set pagesize 0
spool 1
select 'alter table '||table_name||' disable constraint '||constraint_name||' ;'
from user_constraints
/
spool 2
select 'Truncate table '||object_name||' ;'
from user_objects where object_type ='TABLE'
/
spool off
@1.lst
@2.lst
Regards
Himanshu
