Track Oracle Table Last Update Time
There is no built-in feature in Oracle databases to directly view the update time of table data. However, you can achieve this by creating a trigger to record the update time of data. The specific steps are as follows:
- Create a new column to track the time of data updates.
ALTER TABLE your_table ADD last_update_date DATE;
- Create a trigger to update the data update time.
CREATE OR REPLACE TRIGGER update_last_update_date
BEFORE UPDATE ON your_table
FOR EACH ROW
BEGIN
:NEW.last_update_date := SYSDATE;
END;
Whenever the data in the table is updated, the trigger will automatically update the last_update_date column of the corresponding data row with the current time. This allows you to view the update time of the table data by querying the last_update_date column.
