python之TXT数据导入数据库
为了导入数据,可以先对数据做些处理,让其更容易导入数据库 #!/usr/bin/python #coding=utf-8 import _MySQL,sys,time #读入数据函数 def add_data(id,name,created_time): try: conn=_mysql.connect('127.0.0.1','root','') conn.query("set names utf8") conn.query("insert into mysql.test3(%s,%s,%s) values('%s','%s','%s')"%('object_id','object_name','created',id,name,created_time)) result=conn.use_result() conn.close() except _mysql.Error,e: print ("error %d:%s" % (e.args[0],e.args[1])) sys.exit(1) if __name__ =="__main__": f= open("/opt/testdata/aaa.txt","r") time1=time.time() print time.ctime() #读出第一行数据,作为数据表的段名 line=f.readline() content=line.strip().split(",") conn0=_mysql.connect('127.0.0.1','root','') print 'connection is builded succesfully' conn0.query("drop table if exists mysql.test3") conn0.query("create table mysql.test3(%s varchar(90),%s varchar(90),%s varchar(90))"%(content[0][1:-1],content[1][1:-1],content[2][1:-1])) conn0.close() #运用next函数,让for循环从第二行开始读数据 next(f) for line in f: #做一些处理,让每一段分开,放置在一个列表中 content=line.strip().split(",") add_data(id=content[0][1:-1],name=content[1][1:-1],created_time=content[2][1:-1]) f.close() time2=time.time() print time.ctime() #计算导入数据的时间 print 'importing time is %f'%(time2-time1)
