如何檢查DB2中表或列的字符編碼？如何檢查DB2中表或列的字符編碼？
我在DB2數據庫的某些記錄中出現了奇怪的字符，我想知道如何檢查表或列的當前字符編碼集。
因爲它的，我收到一個錯誤。這是堆棧跟蹤。

這取決於DB2平臺和版本。您可能還需要詳細描述如何確定__strange characters__出現在數據庫中，而不是您使用的客戶端的假象。 – mustaccio
同意@mustaccio - 我已經研究過這種數據 - 從一個客戶端我有一個重音y，另一個重音我。這種行爲_may_在複製到記事本的結果中已經產生了一些影響（時間太長，無法準確記住）...因爲我一直在尋找「不尋常」的字符，所以我沒有打算弄清楚哪一個是正確的（通過檢查字節並檢查編碼表）。 –
