How to delete a column from a view

Question

I'm trying to delete a column from a view but can't seem to be able to do it because apparently is missing a keyword. Can someone tell me what I'm missing?

ALTER VIEW REORDERINFO DROP COLUMN name;

After trying again I got the following:

SQL> ALTER VIEW REORDERINFO
AS SELECT isbn,title, phone
FROM books JOIN publisher USING (pubid);

ERROR at line 2: ORA-00922: missing or invalid option

Answer 1

You cannot use ALTER VIEW for removing a column. To recreate the view without the column, use CREATE OR REPLACE VIEW.

From the Oracle documentation:

Use the ALTER VIEW statement to explicitly recompile a view that is invalid or to modify view constraints.
