:::::::::::::::::::::::::::::::: CONFIGURATION ::::::::::::::::::::::::::::::::
:: MySQL Connection Settings
set "MYSQL_BIN_PATH=D:\mysql-8.0.30-winx64\bin"
set "MYSQL_USER=root"
set "MYSQL_PASS=123456"
set "MYSQL_HOST=127.0.0.1"
set "MYSQL_PORT=3306"
set "BACKUP_DB=v2"  :: 数据库名（会自动拼到文件名）

:: Backup File Settings
set "BACKUP_SAVE_PATH=C:\Users\Administrator\Desktop"  :: 备份保存目录

:: 1. 生成规范日期时间（格式：年月日_时分秒，无中文/空格）
:: 处理日期：20251203（年4位+月2位+日2位）
set "DATE_YMD=%date:~0,4%%date:~5,2%%date:~8,2%"
:: 处理时间：232801（时2位+分2位+秒2位），替换空格为0（解决0-9点的空格问题）
set "TIME_HMS=%time:~0,2%%time:~3,2%%time:~6,2%"
set "TIME_HMS=!TIME_HMS: =0!"

:: 2. 拼接最终文件名：full_back_数据库名_年月日_时分秒.sql
set "BACKUP_FULL_PATH=!BACKUP_SAVE_PATH!\!BACKUP_FILE_PREFIX!_!BACKUP_DB!_!DATE_YMD!_!TIME_HMS!.sql"

:: 3. 检查 mysqldump 是否存在
if not exist "!MYSQL_BIN_PATH!\mysqldump.exe" (
    echo Error: mysqldump.exe not found! Check MYSQL_BIN_PATH.
    pause
    exit /b 1
)

:: 4. 执行备份（显示正确的文件名）
echo Backing up database [�CKUP_DB%] to: !BACKUP_FULL_PATH!
echo Please wait...

"!MYSQL_BIN_PATH!\mysqldump.exe" -u!MYSQL_USER! -p!MYSQL_PASS! -h!MYSQL_HOST! -P!MYSQL_PORT! ^
  --databases !BACKUP_DB! ^
  --single-transaction ^
  --routines ^
  --events ^
  --triggers > "!BACKUP_FULL_PATH!" 2>error.log

:: 5. 检查备份结果
if %errorlevel% equ 0 (
    echo.
    echo Success! Backup file: !BACKUP_FULL_PATH!
) else (
    echo.
    echo Error: Backup failed!
    echo Check error log: %cd%\error.log
)
