备份与还原是数据库避不开的主题，而作为DBA，经常会面临将一台机器上的所有数据库重新构建到一台新机器上的要求；
在现在都讲究自动化管理的时代，传统的界面操作备份还原的做法不仅浪费时间和精力，而且还很容易出错，并且这次完成后，
下次再有这样的要求，必须又重头开始（估计做5次就能做得人狂吐）；于是，我们需要一套应对这种频繁操作、耗时、耗精力
的通用处理方法，所以以下批处理脚本就诞生了。
脚本主要的功能：
1. 备份一个服务器上的所有数据库（当然你也可以选择），备份文件按数据库名+日期生成，以.bak 结尾；
2. 将所有的备份文件还原到一台新机器上；
3. 验证磁盘和路径的正确性；
说明：
脚本合适 SQLServer 2005 & 2008 版本；

如何在 PHP 中使用 MySQL 備份和還原？
Jun 03, 2024 pm 12:19 PM
在PHP中備份和還原MySQL資料庫可透過以下步驟實現：備份資料庫：使用mysqldump指令轉儲資料庫為SQL檔。還原資料庫：使用mysql指令從SQL檔案還原資料庫。
iOS 18 新增「已復原」相簿功能 可找回遺失或損壞的照片
Jul 18, 2024 am 05:48 AM
蘋果公司最新發布的iOS18、iPadOS18以及macOSSequoia系統為Photos應用程式增添了一項重要功能，旨在幫助用戶輕鬆恢復因各種原因遺失或損壞的照片和影片。這項新功能在Photos應用的"工具"部分引入了一個名為"已恢復"的相冊，當用戶設備中存在未納入其照片庫的圖片或影片時，該相冊將自動顯示。 "已恢復"相簿的出現為因資料庫損壞、相機應用未正確保存至照片庫或第三方應用管理照片庫時照片和視頻丟失提供了解決方案。使用者只需簡單幾步
在PHP中使用MySQLi建立資料庫連線的詳盡教學
Jun 04, 2024 pm 01:42 PM
如何在PHP中使用MySQLi建立資料庫連線：包含MySQLi擴充（require_once）建立連線函數（functionconnect_to_db）呼叫連線函數（$conn=connect_to_db()）執行查詢（$result=$conn->query()）關閉連線（ $conn->close()）
navicat資料庫檔案在哪
Apr 23, 2024 am 10:57 AM
Navicat 資料庫設定檔的儲存位置因作業系統而異：Windows：使用者特定路徑為%APPDATA%\PremiumSoft\Navicat\macOS：使用者特定路徑為~/Library/Application Support/Navicat\Linux：使用者特定路徑為~/ .config/navicat\設定檔名稱包含連線類型，如navicat_mysql.ini。這些設定檔儲存資料庫連線資訊、查詢歷史記錄和 SSH 設定。
如何在PHP中處理資料庫連線錯誤
Jun 05, 2024 pm 02:16 PM
PHP處理資料庫連線報錯，可以使用下列步驟：使用mysqli_connect_errno()取得錯誤代碼。使用mysqli_connect_error()取得錯誤訊息。透過擷取並記錄這些錯誤訊息，可以輕鬆識別並解決資料庫連接問題，確保應用程式的順暢運作。
navicat資料庫連接url怎麼寫
Apr 24, 2024 am 02:33 AM

如何在 Golang 中使用資料庫回呼函數？
Jun 03, 2024 pm 02:20 PM
在Golang中使用資料庫回呼函數可以實現：在指定資料庫操作完成後執行自訂程式碼。透過單獨的函數新增自訂行為，無需編寫額外程式碼。回調函數可用於插入、更新、刪除和查詢操作。必須使用sql.Exec、sql.QueryRow或sql.Query函數才能使用回呼函數。
如何用 Golang 連接遠端資料庫？
Jun 01, 2024 pm 08:31 PM
透過Go標準庫database/sql包，可以連接到MySQL、PostgreSQL或SQLite等遠端資料庫：建立包含資料庫連接資訊的連接字串。使用sql.Open()函數開啟資料庫連線。執行SQL查詢和插入操作等資料庫操作。使用defer關閉資料庫連線以釋放資源。
