The SQL UPDATE VIEW command can be used to modify the data of a view.

Here in the follwing topics we are discussing, that a view can not be updated (using a UPDATE VIEW statement) if any of the fields of the view is created by using either an AGGREGATE FUNCTION or a GROUP BY clause.

You can use a database link to update a remote object only if you are using Oracle Database distributed functionality.

If you omit to indicate that Oracle Database prohibits any changes to the table or view that would produce rows that are not included in the subquery.

It demonstrates how you can use PL/SQL user-defined functions (UDFs) to supplement the SQL semantics for updating nested tables, and then it shows how you can reshuffle (sort) data store the sorted data in table view columns.

A table view column is an Oracle specific user-defined type (UDT), and is nested table or varray of a scalar data type.

This blog post reviews table view columns, and extends concepts from Oracle Database 11g & My SQL 5.6 Developer Handbook (by the way virtually everything in the book is relevant from My SQL 5.1 forward).

When the query finishes, the libref is disassociated.

The connection to the DBMS is terminated and all data in the library becomes unavailable.
