The first way is writing and executing a query in a SQL document. Once you are connected to your MySQL database ( look here to see how it is done), you can create a view using one of the two following ways.
MYSQL INSERT INTO VIEW DOWNLOAD
Download a free trial, spend a couple of minutes installing it, and let’s get started. We suggest you try dbForge Studio for MySQL, a toolset that covers nearly any operation with MySQL databases you can think of. Now that we know the basic syntax, we need to find a tool that will help us manage our databases and views most effectively.
MYSQL INSERT INTO VIEW HOW TO
If we no longer need a certain view, we can delete it with a simple DROP statement: DROP VIEW warehouse_details How to create a view in dbForge Studio for MySQL Warehouse_id = 55 How to drop a MySQL view
MYSQL INSERT INTO VIEW UPDATE
UPDATE warehouse_detailsįinally, we can check whether the change has been applied using the following query: SELECT * FROM warehouse_details Let’s say we want to change the phone number of the warehouse with the warehouse_id ’55’ through the warehouse_details view using the following UPDATE statement. Now we can query data from this view: SELECT * FROM warehouse_details Now let’s create an updatable view called warehouse_details based on the warehouses table. References to non-updatable views in the FROM clause.Subqueries in the SELECT or WHERE clause referring to the table appearing in the FROM clause.Multiple references to any column of the base table.
Such clauses as GROUP BY, DISTINCT, HAVING, UNION or UNION ALL.However, please note that in order to be updatable, your view must not include any of the following: If you need to update tables through views, you can use the INSERT, UPDATE, and DELETE statements to perform the corresponding operations with the rows of the underlying table.
For that purpose, we calculate the total income using the order_details table data and use the INNER JOIN clause to retrieve order IDs from the orders table and customer names from the customers table. This view gives us information on order income per customer, grouped by order ID. INNER JOIN customers USING (customer_name) SUM(ordered_quantity * product_price) total Our next example is somewhat more complicated since it involves multiple tables (there will be three in our case): CREATE VIEW order_incomes AS How to create a view with JOINs to combine data from multiple tables The output will constitute a table containing three columns: id_number, name, and transaction_date. Now we can move on and execute a statement that selects all the fields in this view: SELECT * FROM transactions If we have a table called customers in our current database, and we would like to request a list of customers with the transaction dates of their orders, the script may look as follows: CREATE VIEW transactions ASĪfter we execute this statement, the transactions object will be available in Views.
This article will show you how to create and manage views in MySQL.
