common create table command in different database

Lets see how a customer table is created in different database

In Oracle:

         create table customer
         (
         cust_id number,
         cust_name varchar2(200),
         cust_gender char(1),
         registration_date date,
         );

In MySQL:
         create table customer
         (
         cust_id int,
         cust_name varchar(200),
         cust_gender char(1),
         registration_date datetime,
         );

In MSSQL:

         create table customer
         (
         cust_id int,
         cust_name varchar(200),
         cust_gender char(1),
         registration_date datetime,
         );

In PostgreSQL:

         create table customer
         (
         cust_id int8, [or cust_id integer]
         cust_name varchar(200),
         cust_gender char(1),
         registration_date date,
         );
