Oracle数据库导出报componet
一、网友问答
问题：我在命令提示符中输入导出指令exp name/pwd@local file=e:123.dmp full=y时出现以下错误：
EXP-00056:遇到Oracle错误6550
ORA-06550：line 1，column 41:
PLS-00302: componet 'SET_NO_OUTLINES'must be declared
ORA_06550:line 1,column 15:
PL/SQL:statement ignored
EXP-00000:导出终止失败
我的客户端是10.2.0。服务器端是10.1.0
解答：这个问题原因是用了高版本的exp去导出低版本的数据。比如你的local数据是10.1的，而却要去导出9i的数据。
方法1：直接到需要导出的那个机器上去做导出，再把文件拷贝过来。
方法2：重新安装一个Oracle客户端，版本要不高于local机器上的那个版本。
二、解决办法和注意事项
上述两种方法均可解决。但方法1有可能没有权限进入远程机器，方法2中有些麻烦。
还有一种方法就是导出为.sql的形式，这种方法是不受版本影响的。
三、注意事项
需要注意的是，若表中还有BLOB或CLOB字段，就无法用.sql的形式导出了。
