python连接oracle，感觉table_list文件内的表名，来卸载数据文件
主脚本：
import os import logging import sys import configparser import subprocess import cx_Oracle #判断输入参数个数 class param(): def check_para(self): if len(sys.argv) != 1: print("请输入正确的参数：yyyymmdd") exit(1) else: print("继续执行") #根据配置文件获取登录信息 class get_dbini(): def get_db(self): config=configparser.ConfigParser() filepath="db.ini" if os.path.exists(filepath): config.read_file(open(filepath)) dbinfo=[config.get("db_oracle","username"), config.get("db_oracle","password"), config.get("db_oracle","ip"), config.get("db_oracle","dbsid")] else: loginfo.info("没有那个配置文件") sys.exit(4) #声明使用全局变量 global username,password,ip,dbsid username=dbinfo[0] password=dbinfo[1] ip=dbinfo[2] dbsid=dbinfo[3] loginfo.info(username+password+ip+dbsid) #导出表数据 class exp_date(): def exp_table(self): with open('table_list','r') as f: list = f.readlines() for i in list: tablename = i.rstrip(' ') exportquery='sqluldr2 user='+username+'/'+password+'@'+ip+':1521/'+dbsid+' query="select * from '+tablename+';" head=no file='+tablename+'.dat field=0x03 record=0x030x0a safe=yes' loginfo.info("开始导出数据: exportquery= "+exportquery) flag= subprocess.check_call(exportquery,shell=True) loginfo.info(flag) #打印日志 class log_set(): def logger_set(self): logger=logging.getLogger('mylogger') logger.setLevel(logging.DEBUG) fh=logging.FileHandler('a.log','w') fh.setLevel(logging.INFO) ch=logging.StreamHandler() ch.setLevel(logging.ERROR) formatter = logging.Formatter('%(asctime)s -%(name)s -%(levelname)s - %(message)s') fh.setFormatter(formatter) ch.setFormatter(formatter) logger.addHandler(fh) logger.addHandler(ch) return logger if __name__=='__main__': loginfo=log_set().logger_set() param().check_para() get_dbini().get_db() exp_date().exp_table()
DB配置文件内容：
db.ini
[db_oracle] username=c##scott password=tiger ip=192.168.1.250 dbsid=orcl
表名字的配置文件：
table_list
BONUS
DEPT
EMP
LEAD_TABLE
SALGRADE
T1
TB_USER
TEST
XGJ
XGJ_2
运行结果：
