Python3操作SQL Server数据库(实例讲解)

import pymssql

conn = pymssql.connect(host='127.0.0.1',
            user='sa',
            password='123',
            database='SQLTest',
            charset='utf8')

#查看连接是否成功
cursor = conn.cursor()
sql = 'select * from student'
cursor.execute(sql)
#用一个rs变量获取数据
rs = cursor.fetchall()

print(rs)

try:
  conn = pymssql.connect(host='127.0.0.1',
              user='sa',
              password='123',
              database='SQLTest',
              charset='utf8')
  cursor = conn.cursor()
  sql = 'insert into student values('0001', '张三', 18, '男', '文学院')'
  cursor.execute(sql)
  conn.commit()
except Exception as ex:
  conn.rollback()
  raise ex
finally:
