Click the down arrow to see the following list you can choose from: A List of the Field Types (Older versions of phpMyAdmin.) A List of Field Types (Newer versions of phpMyAdmin.) As you can see from the image above, theres quite a lotMySQL supports three categories of data types: string, numeric and date/time data types. To set the type of data going into a field, you select an item from the Type drop down list.

It contains information about each customer as well. The customerlist table is a list of people we are going to call customers. The goal is to make the concept of joins clear by showing the results of each join type in an example. In this tutorial, we will use an example database with two tables: customerlist and payments.

PrerequisitesTo follow along with this guide, you will need the following: Creating backups is also more seamless since you can create a single MySQL dump file that contains all your data.Retrieving data is faster, and when creating records you can be sure that data validation rules and referential integrity are maintained especially when using MySQL transactions.In this tutorial, you will use the MySQL BLOB data type to store images with PHP on Ubuntu 18.04. The scheme also centralizes the database, making it more portable and secure because the data is isolated from the file system. This programming approach eliminates the need for creating a separate file system for storing images. This is similar to AUTOINCREMENT column in MySQL or AUTOINCREMENT column in.A Binary Large Object ( BLOB) is a MySQL data type that can store binary data such as images, multimedia, and PDF files.When creating applications that require a tightly-coupled database where images should be in sync with related data (for example, an employee portal, a student database, or a financial application), you might find it convenient to store images such as studentsвЂ™ passport photos and signatures in a MySQL database alongside other related information.This is where the MySQL BLOB data type comes in.

The table has four columns:Product_id: This column uses a BIGINT data type in order to accommodate a large list of products up to a maximum of 2вЃ¶Ві-1 items. CREATE TABLE `products` (product_id BIGINT PRIMARY KEY AUTO_INCREMENT, product_name VARCHAR(50), price DOUBLE, product_image BLOB) ENGINE = InnoDB This command creates a table named products. In this tutorial weвЂ™ll name it test_company:Once the database is created, you will see the following output:Next, create a products table by running: To do this, SSH in to your server and then run the following command to log in to your MySQL server as root:Enter the root password of your MySQL database and hit ENTER to continue.Then, run the following command to create a database. For this tutorial, it isnвЂ™t necessary to create virtual hosts, so you can skip Step 4.YouвЂ™ll start off by creating a sample database for your project. Apache, MySQL, and PHP set up by following the guide on How To Install Linux, Apache, MySQL, PHP (LAMP) stack on Ubuntu 18.04.

After executing this for creating the products table, youвЂ™ll see the following output:/var/: This variable holds the test_user username.DB_PASSWORD : This constant stores the MySQL PASSWORD of the test_user account.DB_HOST: This represents the server where the database resides. Since some products may have floating values (for example, 23.69, 45.36, 102.99), youвЂ™ve used the DOUBLE data type.Product_image: This column uses a BLOB data type to store the actual binary data of the productsвЂ™ images.YouвЂ™ve used the InnoDB storage ENGINE for the table to support a wide range of features including MySQL transactions. YouвЂ™ve used the VARCHAR data type since this field will generally handle alphanumerics up to a maximum of 50 charactersвЂ”the limit of 50 is just a hypothetical value used for the purpose of this tutorial.Price: For demonstration purposes, your products table contains the price column to store the retail price of products. In order for MySQL to handle the generation of new identifiers for inserted columns, you have used the keyword AUTO_INCREMENT.Product_name: This column holds the names of the products.

ATTR_EMULATE_PREPARES, false: This option increases security by telling the MySQL database engine to do the prepare instead of PDO.YouвЂ™ll include the /var/First, create the /var/add the following information into the /var/'VIRTUAL SERVERS','product_image' => file_get_contents('' )$sql = 'INSERT INTO products(product_name, price, product_image) VALUES (:product_name, :price, :product_image)' In the file, youвЂ™ve included the config.php file at the top. ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION: This attribute instructs PDO to throw an exception that can be logged for debugging purposes. DB_NAME, DB_USER, DB_PASSWORD) Toward the end of the file, youвЂ™ve set a couple of PDO attributes: $pdo = new PDO('mysql:host='.

If you are building an application such as a studentsвЂ™ portal or employeesвЂ™ database that requires information and related images to be stored together, then this technology can be of great use to you.For more information about the supported data types in MySQL follow the MySQL Data Types guide. These include portability, security, and ease of backup. YouвЂ™ve also seen the basic advantages of storing images in a database as opposed to storing them in a file system. ConclusionIn this guide, you used the MySQL BLOB data type to store and display images with PHP on Ubuntu 18.04.
