![]() ![]() In this case, we will create a view with the same name as the real table so that the current applications can reference the view as if it were a table. Suppose we want to split a large table into many smaller ones without affecting the current applications that reference the table. We can limit which information users can access by authoring only the necessary data to them.Ī view can also enable the backward compatibility in legacy systems. Let’s have a look at its basic syntax: CREATE USER IF NOT EXISTS 'newusername''hostname' IDENTIFIED BY 'userpassword'. To create a new MySQL user account via the MySQL shell, you need to execute the CREATE USER statement. It also allows us to show only authorized information to the users and hide essential data like personal and banking information. When you do, you also need to type the password for the root account and press Enter: Enter password. This will eliminate the chances of repeatedly writing the same formula in every query, making the code reusable and more readable. Such type of code makes it easier to integrate with our application. We know that View simplifies the complex queries and converts them into a single line of code to use VIEWS. If we are using the complex query, we can create a view based on it to use a simple SELECT statement instead of typing the complex query again. It allows the user to simplify complex queries. MySQL view provides the following advantages to the user: Now, we can verify the view as below: Why we use View? The views can be accessed like normal tables any change performed on a view will also be reflected on base table(s) and vice versa. Finally, click on the Finish button to complete the view creation. In this screen, we will review the script and click the Apply button on the databaseĦ. After completing the script's writing, click on the Apply button, we will see the following screen:ĥ. As soon as we select the " Create View" option, it will give the below screen where we can write our own view.Ĥ. You can only replace a view with a new query that generates the identical set of columns, using the same column names and data types. Next, we need to right-click on the view option, and a new pop up screen will come:ģ. It will pop up the option that can be shown in the following screen.Ģ. Just construct the query as a string and run it with prepared statements. Select any database under the Schema menu, for example, testdb. 1 You can use Prepared Statements to execute this queries. Here, we can see all the previously created databases. Go to the Navigation tab and click on the Schema menu. Now do the following steps for database deletion:ġ. If the view does not exist, CREATE OR REPLACE VIEW. To create a view in the database using this tool, we first need to launch the MySQL Workbench and log in with the username and password to the MySQL server. The CREATE VIEW statement creates a new view, or replaces an existing view if the OR REPLACE clause is given. We can verify the view using the SELECT statement shown in the below image: Create View using MySQL Workbench In this MySQL tutorial, you will learn what is view Create, Join & Drop View with Examples.Views are the virtual tables that shows selective portion of. AS SELECT c.course_name, c.trainer, t.email ![]()
