#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
