基于python连接oracle导并出数据文件

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 osimport loggingimport sysimport configparserimport subprocessimport 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(’n’) 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 loggerif __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##scottpassword=tigerip=192.168.1.250dbsid=orcl

表名字的配置文件：

table_list

BONUSDEPTEMPLEAD_TABLESALGRADET1TB_USERTESTXGJXGJ_2

运行结果：
