![]() ![]() The DEFAULT specifies a default value for the column.Besides the NOT NULL constraint, a column may have additional constraint such as CHECK, and UNIQUE. The NOT NULL constraint ensures that the column will not contain NULL.Each column has a specific data type and optional size e.g., VARCHAR(255) The column_name specifies the name of the column.The following shows the syntax for a column’s definition: column_name data_type(length) column_constraint Code language: SQL (Structured Query Language) ( sql ) In the previous versions, MySQL used MyISAM as the default storage engine. The InnoDB storage engine brings many benefits of a relational database management system such as ACID transaction, referential integrity, and crash recovery. InnoDB became the default storage engine since MySQL version 5.5. If you don’t explicitly declare a storage engine, MySQL will use InnoDB by default. You can use any storage engine such as InnoDB and MyISAM. Third, you can optionally specify the storage engine for the table in the ENGINE clause. Second, you specify a list of columns of the table in the column_list section, columns are separated by commas. If this is the case, MySQL will ignore the whole statement and will not create any new table. It allows you to check if the table that you create already exists in the database. The table name must be unique within a database. Let’s examine the syntax in greater detail.įirst, you specify the name of the table that you want to create after the CREATE TABLE keywords. ) ENGINE=storage_engine Code language: SQL (Structured Query Language) ( sql ) The following illustrates the basic syntax of the CREATE TABLE statement: CREATE TABLE table_name( ![]() The CREATE TABLE statement allows you to create a new table in a database. ![]() Summary : in this tutorial, we will show you how to use the MySQL CREATE TABLE statement to create a new table in the database. ![]()
