Hi Oracle Guys,



I'm a PostgreSQL developer and we wish to implement changing the nullability
of a column.  We are researching all the different syntaxes, standard and
otherwise, for changing a column to NOT NULL and vice versa.



So, what is the exact syntax in Oracle for make a NULL column NOT NULL and
vice versa.



I've tried reading the docs, but I'd prefer to see some actual examples.



It would be much appreciated!



Chris
