Normally sequences are not exported if we give partial export.
For such cases we can use sql to generate quries for sequence droping and creating
select ‘drop sequence ‘||sequence_name||’;’ from user_sequences where sequence_name like’SEQ_DB%’;
select ‘create sequence ‘||sequence_name||
‘ minvalue ‘|| MIN_VALUE ||
‘ maxvalue ‘|| MAX_VALUE ||
‘ start with ‘||last_number||
‘ increment by ‘|| INCREMENT_BY ||
‘ cache ‘||CACHE_SIZE ||
decode(ORDER_FLAG,’Y',’ order ‘)||
decode(CYCLE_FLAG,’Y',’ cycle ‘)||
‘;’
