第一个错误ora_00904:是提示列名无效的缘故，原因可能是在在导出时有些列
已经无效或者丢失，可能是因为两台机器的系统不成造成，在A系统的某些字符在B系统并不认可；原说明如下：
ORA-00904: invalid column name
Cause: The column name entered is either missing or invalid. Action: Enter a valid column name. A valid column name must begin with a letter, be less than or equal to 30 characters, and consist of only alphanumeric characters and the special characters $, _, and #. If it contains other characters, it must be enclosed in double quotation s. It may not be a reserved word.
第二个问题：是由于在导出过程中的sql分析语句出现错误
