To restore a mistakenly deleted table, you can utilize Oracle’s flash back table feature to recover the deleted table. Here are some steps:

  1. Connect to the Oracle database using administrator privileges.
  2. Use the following command to view all deleted tables:
SELECT * FROM recyclebin;
  1. Locate the table you accidentally deleted and use the following command to restore it:
FLASHBACK TABLE 表名 TO BEFORE DROP;
  1. Make sure you have the necessary permissions to execute the command and ensure that the flashback table feature is enabled in the database.

Please note that the flashback table feature can only restore deleted tables, and can only be successful if the table has not been truncated before it was deleted. If the table has been truncated or recreated, the flashback table feature will not be able to recover the data. Therefore, be sure to carefully consider before performing any deletion operation.
