ORACLE-007: Search for deleted data, oracle007 search for deleted data

There are two types of table data to be deleted: delete and trunc.

Trunc makes the data unrecoverable, while delete can also be searched and restored.

If the data is deleted by mistake using delete, you can find the data by using the following SQL statement.

Select * from table name as of TIMESTAMP time where Condition


For example, if the table name tb_test is "delete data within 10 days", the SQL statement is as follows:

Select * from tb_test as of TIMESTAMP sysdate-10where1 = 1;
