0 points
In this article, we would like to show you how to create a view if it doesn't already exist in MS SQL Server.
Quick solution:
xxxxxxxxxx1

SELECT [column1], [column2], ...3
FROM [table_name]4
WHERE condition;To show how the CREATE VIEW IF NOT EXIST statement works, we will use the following table:
Note:
At the end of this article you can find database preparation SQL queries.
In this example, we will create a view that shows all users from Spain if it doesn't already exist.
Query:
xxxxxxxxxx1
CREATE VIEW IF NOT EXISTS [Spain Users] AS2
SELECT [name], [email]3
FROM [users]4
WHERE [country] = 'Spain';To see the view created with the query above simply use:
xxxxxxxxxx1
SELECT * FROM [Spain Users];Result:
create_tables.sql file:
xxxxxxxxxx1
CREATE TABLE [users] (2
[id] INT IDENTITY(1,1),3
[name] VARCHAR(100) NOT NULL,4
[email] VARCHAR(100) NOT NULL,5
[country] VARCHAR(15) NOT NULL,6
PRIMARY KEY ([id])7
);insert_data.sql file:
xxxxxxxxxx1
INSERT INTO [users]2
([name], [email], [country])3
VALUES4
('Tom', 'tom01@email.com', 'Poland'),5
('Chris','chris123@email.com', 'Spain'),6
('Jack','jack32@email.com', 'Spain'),7
('Kim','kim103@email.com', 'Vietnam'),8
('Marco','marco942@email.com', 'Italy'),9
