Cross table update (also known as correlated update, or multiple table update) in Oracle uses non-standard SQL syntax format (non ANSI standard) to update rows in another table. Update data in table A based on two or more common columns in table B.The differences in syntax are quite dramatic compared to other database systems like MS SQL Server or My SQL. Updates based on two or more common columns are normally used for tables where multiple columns work together as a primary key (known as composite primary key).To refer to the remote database in a subquery, append the database link name to the table names in the FROM clause of the subquery.An example of this is shown in the following listing: NOTE If you do not append the database link name to the table names in the FROM clause of UPDATE subqueries, tables in the local database will be used.The purpose of the WITH CHECK OPTION is to ensure that all UPDATE and INSERTs satisfy the condition(s) in the view definition.If they do not satisfy the condition(s), the UPDATE or INSERT returns an error.

A view is actually a composition of a table in the form of a predefined SQL query.

All INSTEAD OF triggers are fired for each row and you cannot narrow down the event by column.

Instead you can check to see what columns are updated in the body of the trigger by using the UPDATING ('column_name') clause.

Should any right be infringed, it is totally unintentional.
