ORA-00900 修改props$中字符集致使

那天在一個羣裏面看到有人在說ORA-00900的錯誤，google.baidu有大量關於ORA-00900的相關信息，其實就是一個update語句致使的，由於update語句並不會立刻刪除舊的值，因此處理起來至關的簡單。下面是本身的測試

 歡迎你們加入ORACLE超級羣：17115662 免費解決各類ORACLE問題,之後BLOG將遷移到http://www.htz.pw

3，bbed處理

由於這裏咱們修改的列的長度是一致的，因此解決的方案有不少的，如，將列的值更改回原來的，將行指針，指向原來的值等方法

 

定位在塊中那一行，可使用dump塊的方法，也能夠直接使用find的方法，這裏我直接使用的find的方法

其實還有不少其它的方法能夠實現的。只要能達到目的，使用本身最熟悉的方法就能夠了。
