MySQL CREATE TABLE

MySQL CREATE TABLE

The MySQL CREATE TABLE command is used to create a new table into the database. A table creation command requires three things:

  • Name of the table
  • Names of fields
  • Definitions for each field

Syntax:

Following is a generic syntax for creating a MySQL table in the database.

mysql> CREATE TABLE table_name (column_name column_type...);   

Example:

Here, we will create a table named "cus_tbl" in the database "customers".

mysql> CREATE TABLE cus_tbl(  
        cus_id INT NOT NULL AUTO_INCREMENT,  
        cus_firstname VARCHAR(100) NOT NULL,  
        cus_surname VARCHAR(100) NOT NULL,  
        PRIMARY KEY ( cus_id )  
      );  

Note:

  1. Here, NOT NULL is a field attribute and it is used because we don't want this field to be NULL. If you will try to create a record with NULL value, then MySQL will raise an error.
  2. The field attribute AUTO_INCREMENT specifies MySQL to go ahead and add the next available number to the id field.PRIMARY KEY is used to define a column as primary key. You can use multiple columns separated by comma to define a primary key.
