Can I really drop that index?

  • Editorial

You believe that an index is unused and so could be removed, and yet, your finger hovers nervously over the metaphorical "delete" button. You can't quite bring yourself to do it. Is it really safe to drop this index? Tony wonders if "invisible indexes" might solve this dilemma.

Question of the Day

Which Table I

I have this code in SQL Server 2022:

CREATE SCHEMA etl;
GO
CREATE TABLE etl.product
(
    ProductID INT,
    ProductName VARCHAR(100)
);
GO
INSERT etl.product
VALUES
(2, 'Bee AI Wearable');
GO
CREATE TABLE dbo.product
(
    ProductID INT,
    ProductName VARCHAR(100)
);
GO
INSERT dbo.product
VALUES
(1, 'Spiral College-ruled Notebook');
GO
CREATE OR ALTER PROCEDURE etl.GettheProduct
AS
BEGIN
    SELECT  ProductName
    FROM product;
END;
GO
When I execute this code as a user whose default schema is dbo and has rights to the tables and proc, what is returned?
