Python连接SQLServer2000或连接mysql代码示例

Posted 2022-12-21 hzjdpawn

1、Python连接SQLServer2000

# 获取连接
import pymssql
db = pymssql.connect(‘127.0.0.1‘, ‘sa‘, ‘ddh123‘, "aaa")

# 获取游标，相当于java中的Statement
cursor = db.cursor()

# 执行sql
sql = ‘‘‘
    insert into t_user 
      (username,password,age,height)
    values 
      (‘jlw‘, ‘23333‘, 31, 172)  
‘‘‘
try:
   cursor = db.cursor()
   cursor.execute(sql)
   print(‘Successfu_sqlserver‘)
   db.commit()
except:
   print(‘Failed_sqlserver‘)
   db.rollback()

cursor.close()
db.close()

2、Python连接MYSQL

import pymysql
db = pymysql.connect(host=‘localhost‘,user=‘root‘, password=‘123‘, port=3306, db=‘aaa‘)
data = 
    ‘username‘: ‘abc333d‘,
    ‘password‘: ‘123456‘,
    ‘age‘: 21,
    ‘height‘:176

table = ‘t_user‘
keys = ‘, ‘.join(data.keys())
values = ‘, ‘.join([‘%s‘] * len(data))

sql = ‘INSERT INTO table(keys) VALUES (values)‘.format(table=table, keys=keys, values=values)
try:
   cursor = db.cursor()
   cursor.execute(sql, tuple(data.values()))
   print(‘Successful‘)
   db.commit()
except:
   print(‘Failed‘)
   db.rollback()
cursor.close()
db.close()
