SQL Create Table Statement

SQL Create Table Statement

A table is a group of data stored in a database.

To create a table in a database you use the CREATE TABLE statement. You give a name to the table and a list of columns with its datatypes.

SYNTAX

CREATE TABLE table_name(Attribute1 Datatype,
                       Attribute2 Datatype,
                       ........);

here:

• Attribute1, Attribute2... -> Column Name
• Datatype... -> type of value you want to column have. For eg. int(size), char(size), Varchar(size),etc.

Here’s an example creating a table named Person:

CREATE TABLE Person(
  Id int not null,
  Name varchar not null,
  DateOfBirth date not null,
  Gender bit not null,
  PRIMARY KEY( Id )
);

In the example above, each Person has a Name, a Date of Birth and a Gender. The Id column is the key that identifies one person in the table. You use the keyword PRIMARY KEY to configure one or more columns as a primary key.

A column can be not null or null indicating whether it is mandatory or not.
