I installed Oracle 11g on my computer. When I export data from Oracle 10g, I get the following error code. I have translated the error in parenthesis.
EXP-00008: 遇到 ORACLE 错误 904 （encouter oracle error 904） ORA-00904: "POLTYP": 标识符无效 (POLTYP: is not valid ) EXP-00000: 导出终止失败 (export fail)
Does someone know why? I believe it is ok to export from Oracle 10g using Oracle 11g client.
