#oracle版

首先新建python脚本(d:/python/orclImport.py)

import os #引入os包

if __name__ == '__main__':

#遍历文件夹下所有的dmp文件，其中filename为所有文件、文件夹的名称。

#因为我文件夹下确定都是dmp文件，所以无需进行特殊判断

for filename in os.listdir("D:\dmp"):

# 调用cmd窗口，并执行dmp的导入命令

# 因为dmp文件数据量太大，我选择一条一条的去执行，就是如此，电脑已经打字都卡了

os.system("imp orcl/123456@127.0.0.1/zrr file=\"D:\dmp\\"+filename+"\" full=y ignore=y")

在命令行执行 python d:/python/orclImport.py
