怎么编写Python代码使得：连接mysql和SqlServer数据库，查询mysql中的t_recruitment_position表和删除SqlServer中的t_position_info表再新建一个t_position_info表，将t_recruitment_position内的数据更改字段名插入到新的t_position_info表，做成每天执行的定时任务

您好！针对您的问题，我可以提供一种可能的Python代码实现方式，具体如下：

import pyodbc
import mysql.connector
import schedule
import time

# 连接mysql数据库
mysql_conn = mysql.connector.connect(
    host="localhost",
    user="root",
    password="password",
    database="test_db"
)

# 连接SqlServer数据库
sqlserver_conn = pyodbc.connect(
    "Driver={SQL Server};"
    "Server=server_name;"
    "Database=db_name;"
    "Trusted_Connection=yes;"
)

# 查询mysql中的t_recruitment_position表
mysql_cursor = mysql_conn.cursor()
mysql_cursor.execute("SELECT * FROM t_recruitment_position")
mysql_result = mysql_cursor.fetchall()

# 删除SqlServer中的t_position_info表
sqlserver_cursor = sqlserver_conn.cursor()
sqlserver_cursor.execute("DROP TABLE t_position_info")

# 新建一个t_position_info表
sqlserver_cursor.execute("CREATE TABLE t_position_info (id INT, position_name VARCHAR(255), salary INT)")

# 将t_recruitment_position内的数据更改字段名插入到新的t_position_info表
for row in mysql_result:
    position_id = row[0]
    position_name = row[1]
    salary = row[2]
    sqlserver_cursor.execute("INSERT INTO t_position_info (id, position_name, salary) VALUES (?, ?, ?)", position_id, position_name, salary)

# 关闭数据库连接
mysql_conn.close()
sqlserver_conn.close()

# 设置定时任务，每天执行一次
schedule.every().day.at("00:00").do(job)

def job():
    # 连接mysql数据库
    mysql_conn = mysql.connector.connect(
        host="localhost",
        user="root",
        password="password",
        database="test_db"
    )
    
    # 连接SqlServer数据库
    sqlserver_conn = pyodbc.connect(
        "Driver={SQL Server};"
        "Server=server_name;"
        "Database=db_name;"
        "Trusted_Connection=yes;"
    )
    
    # 查询mysql中的t_recruitment_position表
    mysql_cursor = mysql_conn.cursor()
    mysql_cursor.execute("SELECT * FROM t_recruitment_position")
    mysql_result = mysql_cursor.fetchall()
    
    # 删除SqlServer中的t_position_info表
    sqlserver_cursor = sqlserver_conn.cursor()
    sqlserver_cursor.execute("DROP TABLE t_position_info")
    
    # 新建一个t_position_info表
    sqlserver_cursor.execute("CREATE TABLE t_position_info (id INT, position_name VARCHAR(255), salary INT)")
    
    # 将t_recruitment_position内的数据更改字段名插入到新的t_position_info表
    for row in mysql_result:
        position_id = row[0]
        position_name = row[1]
        salary = row[2]
        sqlserver_cursor.execute("INSERT INTO t_position_info (id, position_name, salary) VALUES (?, ?, ?)", position_id, position_name, salary)
    
    # 关闭数据库连接
    mysql_conn.close()
    sqlserver_conn.close()

# 循环执行定时任务
while True:
    schedule.run_pending()
    time.sleep(1)

这段代码实现了连接mysql和SqlServer数据库，查询mysql中的t_recruitment_position表和删除SqlServer中的t_position_info表再新建一个t_position_info表，将t_recruitment_position内的数据更改字段名插入到新的t_position_info表，并且将以上操作做成每天执行的定时任务。但是请注意，这段代码仅仅是一种实现方式，具体实现方式还需要根据您的实际需求进行调整。
