How to Find Update Time In Oracle?

To find the update time in Oracle, you can query the last modification time of a table or a specific row by using the LAST_DDL_TIME or LAST_ANALYZED columns in the DBA_TABLES or ALL_TAB_COLUMNS views. Additionally, you can create triggers on tables to log changes and track modification times. You can also enable Flashback Data Archive to track and retrieve historical data changes, including the update time. Another option is to use the AS OF clause in a query to view data as it appeared at a specific point in time. Lastly, you can leverage third-party monitoring tools or Oracle's built-in tools like Enterprise Manager to track and monitor update times in Oracle.

What is the query to get the update timestamp of a row in Oracle SQL?

To get the update timestamp of a row in Oracle SQL, you can use the following query:

1
2
3

SELECT SCN_TO_TIMESTAMP(ORA_ROWSCN) AS UPDATE_TIMESTAMP
FROM your_table
WHERE your_condition;

Replace your_table with the name of the table and your_condition with the condition that identifies the specific row you are interested in. This query will return the update timestamp of the row in the specified table.

What is the function to determine the last update time in Oracle database?

The function to determine the last update time in Oracle database is the LAST_DDL_TIME column in the ALL_OBJECTS, DBA_OBJECTS or USER_OBJECTS view. This column stores the timestamp of the last DDL (data definition language) operation performed on that particular object (table, index, view, etc.). You can query this column along with other relevant columns to retrieve the information about the last update time for a specific object in the database.

What is the timestamp of the most recent update in Oracle?

The most recent update in an Oracle database can be checked by querying the LAST_DDL_TIME column in the ALL_OBJECTS data dictionary view. This column stores the timestamp of the last DDL (Data Definition Language) operation on an object.

To find the most recent update timestamp in Oracle, you can run the following query:

1
2

SELECT MAX(LAST_DDL_TIME)
FROM ALL_OBJECTS;

This query will return the most recent timestamp of any DDL operation on an object in the Oracle database.

What is the SQL statement to display the latest update time in Oracle?

To display the latest update time of a table in Oracle, you can use the following SQL statement:

1
2

SELECT MAX(ora_rowscn) AS last_update_time
FROM your_table_name;

Replace your_table_name with the name of the table you want to retrieve the latest update time from. This query will return the system change number (SCN) of the last update performed on the table, which can be used to determine the approximate time of the last update.
