sql 使用SchemaBinding的MS SQL视图

Posted 2021-05-13

CREATE VIEW dbo.vProductNumLike_BE
WITH SCHEMABINDING
AS
  SELECT Name,ProductNumber
  FROM   Production.Product
GO;

ALTER TABLE Production.Product
    ALTER COLUMN ProductNumber nvarchar(30)
    
-- Won't work because SCHEMABINDING
-- is referencing the table
-- and prevents us from making schema changes.
