• No data may be inserted to simple

views that contain references to any

virtual column such as

ROWID,

CURRVAL,

NEXTVAL,

and ROWNUM.

• No data may be inserted into simple

views that are created with

the read only option.

Users will have problems inserting

data into views if the underlying table

has NOT NULL constraints on it. This

can be eliminated with use of a default

value for the NOT NULL column

in the table definition.
