very day a developer somewhere needs to write code to iterate through SQL Server™ system objects, query and update tables in linked servers, handle optimistic concurrency, and retrieve column and stored procedure metadata. In this month's column, I will address these and other T-SQL development scenarios based on some of the questions I most frequently receive from readers.
How prepared are you for your next interview? How prepared are you to give one? SQLServerCentral.com has compiled a number of questions from our ever popular Question of the Day into a book. Read about the project and show your support today by picking up a copy.
There are plenty of good sources of information about how to deploy SQL Server in a secure fashion. However, these resources are often targeted at database administrators tasked with securing already developed applications. In addition, there is a rich body of information that discusses writing secure .NET and ASP.NET code, including .NET code that accesses SQL Server. However, many of these resources focus on the data access code that runs on the application servers rather than the Transact-SQL (T-SQL) code that executes within SQL Server. Developing T-SQL code that runs securely on SQL Server is the primary focus of this column.
Andy started a contest this summer to see who could develop a T-SQL method of keeping a bowling score. He's finally gotten around to the results after the damage from the hurricanes was cleaned up. See who won and see the code that does the trick.
One of the biggest performance gains built into SQL Server is the stored procedure. In this article by Brian Kelley, he shows you how to fully utilize, debug and monitor the caching of such objects.
A common requirement when building a data warehouse is to be able to get all rows from a staging table where the business key is not in the dimension table. For example, I may want to get all rows from my STG_DATE table where the DateID is not in DIM_DATE.DateID.
SQL Server was designed to make the DBA job easier, distribution of security, automated procedures, etc. But in some areas it either does not go far enough, or a feature is used for an unintended purpose. One of those areas comes into play when allowing many people to create databases. Author Eli Leiba brings us a tecehnique he uses to close the gap and track down those newly created databases.
One of the new tasks in SQL Server 2005 is the For Loop Container. In this article we will demonstrate a few simple examples of how this works. Firstly it is worth mentioning that the For Loop Container follows the same logic as most other loop mechanism you may have come across, in that it will continue to iterate whilst the loop test (EvalExpression) is true. There is a known issue with the EvalExpression description in the task UI being wrong at present. (SQL Server 2005 Beta 2).
SQL Server Analysis Services includes the ability to capture information about every query run against a cube. Author Ramunas Balukonis showed us last time how to query this data. This time he brings us a method of interperting which dimensions are actually be used in satifying Analysis Services queries.
SQL Server 2005 has made it a lot easier for us to loop over a collection and with each iteration do something with the item retrieved. In this article we are going to show you how to iterate over a folder looking at the files within and doing something with those files. In this instance we will be entering the filename into a SQL Server table and we will then load the actual files we have just found into another SQL Server table. You will note here that there is still the need to load the file names into a table as an intermediate step just as we need to do in SQL Server 2000.

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
