pyodbc链接sqlserver

import pyodbc

# DRIVER={SQL Server};DATABASE=数据库名;SERVER=服务器所在的计算机名,端口号;UID=你的用户名;PWD=你的密码
odbc = 'DRIVER={SQL Server};SERVER=127.0.0.1,1433;DATABASE=sqldbtest;UID=sa;PWD=123456'
#1.链接数据库
db =pyodbc.connect(odbc,autocommit=True,)#使用 cursor()方法创建一个游标对象 cursor

#2.游标
cursor =db.cursor()#使用 execute()方法执行 SQL 查询
#编码
conn.setencoding(encoding='utf-8')

#3.执行sql
#1.查询
s1 = """
select * from test_name where name= ?
"""
cursor.execute(s1,("码神",))

#获取结果
res1 = cursor.fetchall() # [(2, '李四', '男', '18852671311', 19), (3, '王五', '女', '18852671303', 17)]
# res2 = cursor.fetchone() #(1, '张三', '男', '18852671307', 23)
# res3 = cursor.fetchmany(2)
# print(res1)
#结果封装成字典
a = [dict(zip([column[0] for column in cursor.description], row))
             for row in res1]

print(a)
#2.增
a1 = """
# insert into test_name values(?,?,?,?)
"""
# cursor.execute(a1,("码神1","男","18852671111",21))


#5.关闭
# db.commit()
# db.rollback()
cursor.close()
db.close()
