Python操作sql，备份数据库

1、批量执行sql

import pymysql

# 执行批量的 SQL 语句
def executeBatchSql(cursor, sqlStatements):
    for sql in sqlStatements:
        try:
            cursor.execute(sql)
            print('Executed SQL statement:', sql)

        except Exception as e:
            print('Error executing SQL statement:', e)

# 创建数据库连接
connection = pymysql.connect(
    host='xx.xx.xx.xx',
    port=xx,
    user='root',
    password='xx',
    database='xx',
    autocommit=True  # 设置自动提交模式
)

# 连接数据库
try:
    with connection.cursor() as cursor:
        print('Connected to database')

        # 执行批量的 SQL 语句
        sqlStatements = [
            "UPDATE conveyor_exception_time SET date = DATE_SUB(CURDATE(), INTERVAL 1 DAY); ",
            "UPDATE detection_ng_analysis SET date = CURDATE(); ",
            "UPDATE single_data_analysis SET date = CURDATE(); ",
            "UPDATE area_data_analysis SET date = CURDATE(); ",
            "UPDATE store_area SET status = FLOOR(RAND() * 8);",
            # "UPDATE area_data_analysis SET `date`=DATE_SUB(CURDATE(), INTERVAL 0 DAY);",

            # "",
        ]

        executeBatchSql(cursor, sqlStatements)

finally:
    # 关闭数据库连接
    connection.close()
    print("\033[32;44;1mSQL执行完成, Mock数据初始化完成...\033[0m")

2、备份数据库

import subprocess

def backup_mysql_database(host, port, user, password, database, output_file):
    # 构建备份命令
    command = f"mysqldump --host={host} --port={port} --user={user} --password={password} {database} > {output_file}"
    
    try:
        # 执行备份命令
        print("数据库备份进行中，请稍等...")
        subprocess.run(command, shell=True, check=True)
        print("数据库备份成功！")
    except subprocess.CalledProcessError as e:
        print(f"数据库备份失败：{e}")

# 调用备份函数
host='xx.xx.xx.xx'
port=xx
user='root'
password='xx'
database='xx'
backup_mysql_database(host, port, user, password, database, "./data/jeecg-boot.sql")

3、使用shell执行python脚本

#!/bin/bash

# 切换到Python脚本所在的目录

# 执行Python脚本
python sql.py

# 添加等待命令，不让脚本关闭
read -p "Press any key to exit..."
