ApsaraDB RDS:修改字元集定序與時區

更新時間:Dec 17, 2024

如果RDS SQL Server執行個體的系統字元集定序和時區設定與商務邏輯不符,或者應用程式需要處理多個時區的資料時,您可以通過修改資料庫執行個體的字元集定序和時區配置來確保資料在不同時區之間的轉換和展示準確無誤。

背景資訊

  • 執行個體預設的字元集定序:Chinese_PRC_CI_AS

  • 執行個體預設的時區:China Standard Time

  • 系統庫包括mastermsdbtempdbmodel

說明
  • 關於可選擇的字元集定序和時區,請以控制台顯示為準。

  • 如果您要修改自建資料庫的字元集定序,請使用ALTER DATABASE <自建資料庫名稱> COLLATE <字元集定序>命令。

使用限制

修改系統字元集定序

說明
  • 修改字元集前,請確保執行個體中沒有任何使用者建立的資料庫(非系統資料庫)。執行個體中存在使用者資料庫時,控制台將不顯示字元集修改入口。

  • 如果刪除了執行個體中的資料庫,刪除任務可能還在備執行個體中等待執行,為避免衝突,請確定主備執行個體均沒有資料庫後再修改字元集定序。

  1. 訪問RDS執行個體列表,在上方選擇地區,然後單擊目標執行個體ID。

  2. 在左側導覽列中單擊資料庫管理

  3. 資料庫管理頁面,單擊修改系統字元集定序

  4. 在彈出的對話方塊中,設定系統字元集定序,單擊確定

    重要

    修改字元集會重啟執行個體,該過程將持續2~10分鐘,期間執行個體將處於不可用狀態。

  5. 您可以在執行個體基本資料頁面查看修改後的系統資料庫字元集。

    重要

    修改時區會重啟執行個體,高可用系列和叢集系列執行個體將停機1分鐘內,基礎系列執行個體約停機5分鐘內,停機期間執行個體將處於不可用狀態。

  5. 在彈出對話方塊中,再次單擊確定

  6. 您可以在執行個體基本資料頁面查看修改後的時區。

時區與UTC位移量對照表

說明

部分國家在夏令時開始和結束時,需要手動將時鐘調快或調慢一小時,以切換到夏令時或返回到標準時間。夏令時(Daylight Saving Time,DST)是一種在一年特定時段內調整時鐘的措施,通過將當地時間調整為比標準時間提前一小時,以此節省能源等。具體交替開始和結束日期因國家和地區而有所不同。
