可以用工具導(dǎo)出或者自己寫個procedure直接把sequence的sql 存到1個文件中，然后執(zhí)行文件即可

procedure dump_all_sequences is

l_file_handle UTL_FILE.file_type;

begin

l_file_handle := UTL_FILE.fopen('PLSQL_OUTPUT',

'all_sequences.sql',

'W',

32000);

for c in (select sequence_name,

min_value,

max_value,

increment_by,

cycle_flag,

order_flag,

cache_size,

last_number

from user_sequences

order by sequence_name) loop

utl_file.put_line(l_file_handle, '--create ' || c.sequence_name);

utl_file.put_line(l_file_handle,

'create sequence ' || c.sequence_name);

utl_file.put_line(l_file_handle, 'minvalue ' || c.min_value);

utl_file.put_line(l_file_handle, 'maxvalue ' || c.max_value);

utl_file.put_line(l_file_handle, 'start with ' || c.last_number);

utl_file.put_line(l_file_handle, 'increment by ' || c.increment_by);

if c.cache_size <> 0 then

utl_file.put_line(l_file_handle, 'cache ' || c.cache_size);

else

utl_file.put_line(l_file_handle, 'nocache');

end if;

if c.cycle_flag = 'Y' then

utl_file.put_line(l_file_handle, 'cycle');

end if;

if c.order_flag = 'Y' then

utl_file.put_line(l_file_handle, 'order');

end if;

utl_file.put_line(l_file_handle, ';');

utl_file.put_line(l_file_handle, '/');

end loop;

end;
