In Oracle, there are several methods to view update records.

  1. Flashback Query can be utilized to view historical records. For example, the following statement can be used to see data from a specific table before a certain point in time:
SELECT * FROM table_name AS OF TIMESTAMP TO_TIMESTAMP('YYYY-MM-DD HH24:MI:SS', 'YYYY-MM-DD HH24:MI:SS') WHERE condition;
  1. Utilize Oracle LogMiner to view the update operations in the database. Start LogMiner first, then use the following statement to query the update records:
SELECT SQL_REDO FROM V$LOGMNR_CONTENTS WHERE OPERATION = 'UPDATE' AND SEG_NAME = 'table_name' AND TIMESTAMP >= TO_TIMESTAMP('YYYY-MM-DD HH24:MI:SS', 'YYYY-MM-DD HH24:MI:SS');
  1. Enabling the Audit Trail feature in Oracle allows for detailed information on update operations to be recorded. This audit information can be viewed by querying the AUD$ table.

Here are several commonly used methods to view updated records in Oracle. Choose the appropriate method based on your specific needs and circumstances.
