import pymysql db = pymysql.connect("localhost","root","hy1102","TESTDB",charset='utf8') cursor = db.cursor() list=[] with open("E:\ee.txt","r") as f: for line in f: ls = line.split() for i in range(0,len(ls)): if ls[i] == "NULL": ls[i] = None list.append(ls) f.close() sql ="""insert into shohin VALUES (%s,%s,%s,%s,%s,%s)""" try: cursor.executemany(sql,list) db.commit()
except:
db.rollback() db.close()
注意事项:
- charset='utf8' : 在有中文字符时必须写上
- 使用excutemany(sql,list),可以一次处理大量的数据,且效率颇高。文件中的NULL目前采用的方式是手动替换成None
- list中的数据可以是list也可以是tuple
- excutemany中sql的替换符必须是%s
