CREATE TABLE STATEMENT

CREATE TABLE STATEMENT

The syntax for the SQL CREATE TABLE statement 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 suppliers
( supplier_id number(10) not null,
  supplier_name varchar2(50) not null,
  contact_name varchar2(50)
);
