Tokenizing a String Using PARSENAME

SQL Server string manipulation using T-SQL leaves lots to be desired. Many postings and complaints about T-SQL deal with strings, but there are ways to work with it. Author Eli Leiba brings us a way to split out portions of a string that contains tokens with a user defined function. Read on to see how this is accomplished and the code used to perform the splitting.

Clustering for Indexes

There is nothing spectacular about using indexes per say. However, on many occasions I have come across a variety of SQL coders that never consider validating that the index they think they are using is efficient or even being used at all. We can all put indexes on the columns that we think will be required to satisfy individual queries, but how do we know if they will ever be used. You see, if the underlying table data is constructed, contains, or is ordered in a particular way, our indexes may never be used. One of the factors around the use of an index is its clustering factor and this is what this article is about.

Cursors with SQL 2000 Part 1

This series of articles will examine the purposes, uses, and optimization of cursors in SQL 2000. SQL languages are designed so groups of records, or sets, can be manipulated easily and quickly. The speed at which groups of data can be altered, updated and deleted, demonstrates why working with sets is the preferred method. However, there are places where cursors are a better choice.

Question of the Day

Which Result II

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
    exec('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?
