import pymysql host='localhost' user='root' passwd='root' port=3306 db='test' db=pymysql.connect( host=host, user=user, passwd=passwd, db=db, port=port, charset='utf8', cursorclass = pymysql.cursors.DictCursor ) cursor=db.cursor() sql="select * from documents" try: cursor.execute(sql) result=cursor.fetchall() for i in result: for j in i: print(j,"=>",i[j]) print(" ") except: print('error') db.close()
在默认情况下cursor方法返回的是BaseCursor类型对象,BaseCursor类型对象在执行查询后每条记录的结果以列表(list)表示。如果要返回字典(dict)表示的记录,就要设置cursorclass参数为MySQLdb.cursors.DictCursor类。
