Recovering Deleted Oracle Database Table Records Without Restore option.

Have you ever accidentally deleted data from an Oracle database and wondered if there’s a way to recover it without restoring from a backup? Good news—there are multiple ways to recover deleted records, depending on your database configuration and how long ago the deletion occurred.

✅ Here are the top recovery methods:

1️⃣ Flashback Query (AS OF TIMESTAMP)

If UNDO data is still available, you can query past records:

sql        

CopyEdit

SELECT * FROM your_table AS OF TIMESTAMP (SYSTIMESTAMP - INTERVAL '1' HOUR);

2️⃣ Flashback Table

If an entire table was affected, you can restore it to a previous timestamp:

sql        

CopyEdit

FLASHBACK TABLE your_table TO TIMESTAMP (SYSTIMESTAMP - INTERVAL '1' HOUR);

🔹 Ensure row movement is enabled:

sql        

CopyEdit

ALTER TABLE your_table ENABLE ROW MOVEMENT;

3️⃣ Flashback Drop (For Dropped Tables)

If the table was dropped, you can recover it from the Recycle Bin:

sql        

CopyEdit

FLASHBACK TABLE your_table TO BEFORE DROP;

4️⃣ LogMiner (Analyzing Redo Logs)

Oracle LogMiner allows you to extract SQL statements, including deleted data:

🔹 Enable supplemental logging, analyze redo logs using DBMS_LOGMNR, and query V$LOGMNR_CONTENTS to identify deleted rows.

5️⃣ Undo Data (AS OF SCN)

You can recover data using System Change Numbers (SCN) if undo records exist:

sql        

CopyEdit

SELECT * FROM your_table AS OF SCN <SCN_number>;

6️⃣ Oracle Data Pump (Export/Import)

If you have a recent export, use Data Pump to re-import the lost data.

7️⃣ Third-Party Tools

Tools like Quest Toad or Oracle Recovery Manager (RMAN) can analyze redo logs and help recover data.
