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. Base tables and views share the same namespace within a database, so a database cannot contain a base table and a view that have the same name. To create the view explicitly in a given database, specify the name as dbname.viewname when you create it. The above MySQL statement will create a view 'viewauthor' taking records (for all columns) of author table if those records contain the value 'USA' for country column. CREATE VIEW viewauthor AS SELECT FROM author WHERE country'USA'. The longer answer is that MySQL is very unlikely to use an index with leading column of happenedid for the view query. 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. By default, a new view is created in the default database. CREATE VIEW command can be used with WHERE clause. Including the score column in the index will allow the query to satisfied entirely from the index pages, without having to visit (lookup) the data pages referenced by the index. It also allows us to show only authorized information to the users and hide essential data like personal and banking information. CREATE VIEW custinvserv AS SELECT c.FirstName, c.LastName, i.InvoiceDate, i.InvoiceID FROM CUSTOMER c JOIN INVOICE i ON c.CustomerID i.InvoiceID JOIN INVOICEITEM ii ON ii.InvoiceID i.InvoiceID JOIN SERVICE s ON ii. This will eliminate the chances of repeatedly writing the same formula in every query, making the code reusable and more readable. to create a view with a subview you have to do it in two steps. 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? 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. 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. Select any database under the Schema menu, for example, testdb. 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. 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. We can verify the view using the SELECT statement shown in the below image: Create View using MySQL Workbench so let's create migration with views.AS SELECT c.course_name, c.trainer, t.email Now we need to use this query on our live database with laravel migration. so let's simple example bellow:īellow my sql query for creating view and drop view: so we don't require to fire again and again same query on server. In this example, we will create "view_user_data" view and i will get count posts and comments of that user. if you create simple view then you can easily get data from that view. In this post, i will show you how to create mysql view using laravel migration and how to use mysql view with laravel eloquent model.īasically, we are using sql view because we don't require to write long query on our database again and again. You can create mysql view using migration in laravel 6, laravel 7, laravel 8, laravel 9 and laravel 10. Let's see bellow example laravel using mysql views. i explained simply step by step how to use mysql view in laravel. Here you will learn laravel migration make view. I’m going to show you about laravel migration create view. In this short tutorial we will cover an how to call mysql view in laravel.
