The basic syntax for a CREATE TABLE is:
CREATE TABLE table_name
(column1 datatype null/not null,
column2 datatype null/not null,
...
);
Each column must have a datatype. The column should either be defined as "null" or "not null" and if this value is left blank, the database assumes "null" as the default.
For example:
CREATE TABLE supplier | |||
( | supplier_id | numeric(10) | not null, |
supplier_name | varchar2(50) | not null, | |
contact_name | varchar2(50) | ||
) |
