好的,以下是Python代码实现该功能:
```python
import pymysql
# 连接数据库
conn = pymysql.connect(
host='localhost',
user='root',
password='123456',
database='test_db',
charset='utf8'
)
# 获取游标
cursor = conn.cursor()
# 查询Student表中的所有数据
sql = "SELECT * FROM Student"
cursor.execute(sql)
results = cursor.fetchall()
# 将结果写入文件
with open('E:/IOTest/student.txt', 'w') as f:
for row in results:
f.write(str(row) + '\n')
# 关闭游标和数据库连接
cursor.close()
conn.close()
```
该代码连接了本地的 MySQL 数据库,查询了 Student 表中的所有数据,并将结果写入了 E:/IOTest/student.txt 文件中。你可以根据自己的需要修改代码中的数据库连接信息和文件路径。
