ALTER TABLE studentĬollege VARCHAR(50) DEFAULT 'ABC Group of College' For example, I want to create a new column college with the default value ‘ ABC Group of College‘ because all the students belong to the same college. Suppose we want to create a new column along with the default value. Example: MySQL adds a column with a default value | date_of_admission | date | YES | | NULL | |Īs you can see in the above example, A new column date_of_adimmision has been created with DATE TYPE.
To check, use DESC table_name statement as follows. Now, I am going to insert some records into this table by using the INSERT INTO statement.Įxample: Add column in MySQL with default value null ALTER TABLE studentĪfter executing the above statement, A new column date_of_admission will create.
If you are able to see the above output it means our table is created successfully. | last_name | varchar(50) | YES | | NULL | | | first_name | varchar(50) | YES | | NULL | | | roll_no | int | NO | PRI | NULL | auto_increment | | Field | Type | Null | Key | Default | Extra | To check whether the table is created or not, use the DESC keyword which is as follows. CREATE TABLE student (Īfter, executing the above statement, your table will be created successfully. To add a new column in an existing table in MySQL, first I will create a table called student using CREATE TABLE statement. Now it’s time to come to implement the above syntax by examples.
Which as follow.ĪDD column_name column_definition ,ĪDD column_name column_definition To add multiple columns in MySQL, you have to specify all the new columns along with their definition separated by a comma (, ). Third, MySQL allows us to add a new column as the first column of the table by using the FIRST keyword otherwise a add new column just after any existing column just by specifying the AFTER existing_column.If you do not specify anything it will create a new column at the end of all the columns. You need to remember one thing here, Here COLUMN is the optional keyword, that’s why you can omit it if you want. Second, You have to specify the name of the new column along with its definition just after the ADD statement.First, you have to specify the name of the table after ALTER TABLE statement.Let’s understand the above syntax in more detail so that you can be aware more of it. ALTER TABLE table_name ADD column_name column_definition To add a new column in the MySQL table, We will use the ALTER TABLE ADD COLUMN statement which is as follows. The First will be using MySQL client and the second will be Using the Workbench application. Here, We will see a total of two ways to add a new column in an existing table in MySQL step by step. At that time, I used to use this MySQL statement to add a new column in MySQL which I am about to tell you about throughout this article. Most of the time my requirement was to add a new column in the existing table as per the requirement of the projects. In this article, You will learn everything about add a new column in an existing table in MySQL with the help of the MySQL client and workbench.Īs a developer, I have faced this issue multiple times.
