python pymysql 怎么让查询返回的字典

Posted 2023-04-03

参考技术A m = dict()#m = m['a'] = 1 #赋值m['b'] = 2print m['a'] #取值就这么简单。 如果解决了您的问题请采纳！ 如果未解决请继续追问 参考技术B import pymysql

conn = pymysql.connect(conUrl,user=username, passwd=passwd, db=db, port=3306, connect_timeout=5)
# 获取数据库游标对象
cursor = conn.cursor(cursor = pymysql.cursors.DictCursor)

cursor.execute(sql,params)

result = cursor.fetchall()
返回的result 是dict类型

python查询mysql以字典返回

# *_*coding:utf-8 *_*
import pymysql

conn = pymysql.connect(host=‘192.168.33.10‘, user=‘root‘, passwd=‘root‘, db=‘spider‘, charset=‘utf8‘)
cur = conn.cursor(cursor=pymysql.cursors.DictCursor)

sql = "select * from topic order by id asc "
cur.execute(sql)  # 返回受影响的行数
res = cur.fetchall()  # 返回数据,返回的是tuple类型

for item in res:
    print(item[‘id‘])
cur.close()
conn.close()
