Excel in the Clouds
Today Steve Jones talks about a new use for cloud computing with Excel to analyze large sets of data.

Unstructured and XML semi-structured data is now used more than structured data. But fixed structured data still keeps businesses running day in and day out, which requires consistent predictable highly principled processing for correct results. For this reason, it would be very useful to have a general purpose SQL peer-to-peer collaboration capability that can utilize highly principled hierarchical data processing and its flexible and advanced structured processing to support dynamically structured data and its dynamic structured processing. This flexible dynamic structured processing can change the structure of the data as necessary for the required processing while preserving the relational and hierarchical data principles. This processing will perform freely across remote unrelated peer locations anytime and transparently process unpredictable and unknown structured data and data type changes automatically for immediate processing using automatic metadata maintenance.
It seems that archival isn't on the mind of most designers when they first build a database, which is OK, but DBAs ought to be building skills to implement this if the data size grows large.
This week Steve Jones notes there were quite a few patches from Microsoft for a variety of products. No SQL Server specific security patches, but that doesn't mean that DBAs shouldn't be patching systems.
Of all the technical solutions to the problem of slowly changing dimensions, the T-SQL MERGE statement is one of the most elegant.
Identifiers aren't locators, and they aren't pointers or links either. They are a logical concept in a relational database, and, unlike the more traditional methods of accessing data, don't derive from the way that data gets stored. Identifiers uniquely identify members of the set, and it should be possible to validate and verify them. Celko somehow involves watches and taxi cabs to illustrate the point.
Come to Indianapolis on June 25, 2011 for a free one day training event on SQL Server.
This Friday Steve Jones has a disaster recovery poll. When you have a true disaster, often there are multiple things that go wrong and cause a cascading failure. Is this common, let us know what your experience is this Friday.

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
exec etl.GettheProduct
When I execute this code as a user whose default schema is dbo and has rights to the tables and proc, what is returned? See possible answers
