If the DML happened in the last few days (or however long you keep your archived logs), you could use Log Miner to extract the timestamps but that is going to be a very expensive operation particularly if you're getting timestamps for many rows.

Using views encourages the use of Shared SQL with the benefit of reduced memory usage.The data dictionary views ALL_UPDATABLE_COLUMNS, DBA_UPDATABLE_COLUMNS, and USER_UPDATABLE_COLUMNS indicate which view columns are updatable.A synonym is an alternative name for objects such as tables, views, sequences, stored procedures, and other database objects.You generally use synonyms when you are granting access to an object from another schema and you don't want the users to have to worry about knowing which schema owns the object.encounters a change to a Data Row, it uses the Insert Command, Update Command, or Delete Command to process the change. Rows(0) category Row("Category Name") = "New Beverages" adapter. Write Line("Rows after update.") Dim row As Data Row For Each row In category Table. Write Line(": ", row(0), row(1)) Next End Using End Sub either by returning the auto-increment value as an output parameter of a stored procedure and mapping that to a column in a table, by returning the auto-increment value in the first row of a result set returned by a stored procedure or SQL statement, or by using the are sent to the data source is important.

This allows you to maximize the performance of your ADO. For example, if a primary key value for an existing row is updated, and a new row has been added with the new primary key value as a foreign key, it is important to process the update before the insert. By specifying a subset of rows to be updated, you can control the order in which inserts, updates, and deletes are processed. From Oracle database 11g release 2 onwards, each database has at least one edition, the default being CONN / AS SYSDBA SELECT property_value FROM database_properties WHERE property_name = 'DEFAULT_EDITION'; PROPERTY_VALUE -------------------------------------------------------------------------------- ORA$BASE SQL is omitted, the parent is assumed to be the leaf edition.In 11g R2 an edition can only have a single child, so this clause is not needed, but hints that editions with multiple children will be possible in future.Instead I will give a little background information, then focus on two examples of its use to give you an idea of what it is capable of.An edition is effectively a version label that can be assigned to all editionable objects in a schema.When a new edition is used by a schema, all editionable objects are inherited by the new edition from the previous edition.
