SQL 更新视图

您可以使用下面的语法来更新视图：

SQL CREATE OR REPLACE VIEW Syntax
CREATE OR REPLACE VIEW view_name AS
SELECT column_name(s)
FROM table_name
WHERE condition
现在，我们希望向 "Current Product List" 视图添加 "Category" 列。我们将通过下列 SQL 更新视图：

CREATE VIEW [Current Product List] AS
SELECT ProductID,ProductName,Category
FROM Products
WHERE Discontinued=No
