oracle 10g exp问题

[qingtianhit]

以下是我测试exp用的表和数据
-- Create table
create table TEST
(
ID NUMBER(3)
);
insert into TEST (ID)
values (1);
insert into TEST (ID)
values (2);
insert into TEST (ID)
values (3);
insert into TEST (ID)
values (4);
commit;


环境： RedHat linux As5
数据库:oracle 10g
在执行exp命令时报错如下，请各位高手指教下..
~#exp test/test123@testdb file=1.dmp tables=TEST query=\" where id>2 \"

我自己试出来了... 逻辑符号前要加"\"
exp test/test123@testdb file=1.dmp tables=TEST query=\" where id\>2 \"

check all there escape characters.
query=\" where id>2 \"======> query=\" where id \>2 \"

[真的不知道取什么名]
