Re: DDL question

The utilities that generate DDL from tables will insert NOT NULL by
default. But you can just remove it before running it in order to
facilitate null data in columns.

I need to create a new table with the same fields as another table that

both CREATE TABLE LIKE and CREATE TABLE AS(). Both methods create the new
table with fields that do not allow NULL, which is the DDS default.

Does anyone know how to create the new table with all of the fields being
nullable, or is there a way to execute one command to change all of the
columns to nullable, instead of executing an ALTER TABLE command for each
column?

Thank you,
