Create table

Lets say I want to create an employee table with below fields
id : Integer
firstName : String
lastName : Stirng
salary : double
mailId :String

Before creating a table, create a database and tell MySQL use this database.

CREATE DATABASE sample;
USE sample;

Syntax
CREATE TABLE table_name(
   column1 datatype,
   column2 datatype,
   column3 datatype,
   .....
   columnN datatype,
   PRIMARY KEY( one or more columns )
);

Example
CREATE TABLE employee
(
 id int,
 firstName varchar(30),
 lastName varchar(30),
 salary decimal,
 mailId varchar(30),
 PRIMARY KEY(id)
);

Above statement creates employee table and makes id as a primary key for employee table.
