Database Files & Objects – Part 4

admin

Today, I will be continuing my talk on database objects that can be viewed through the system catalog views or system stored procedures. A Microsoft SQL Server database is composed of many different objects. We will be investigating how to retrieve information on these objects in the [MATH] sample database. Please see my first article that creates this database. I will be focusing on functions, stored procedures, triggers and views in this article. Let’s use the USE statement to select the sample database.

Nashua – SQL Saturday #146

admin

I am totally pumped up about having the opportunity to present at SQL Saturday #146 in Nashua. I will be posting an updated version of the presentation with TSQL code before the end of the weekend. I hope you have time to attend cool event on October 20th, 2012! Topic: Effective use of temporary tables Abstract: Every developer eventually comes against business logic that can’t be handled with a single simple or complex query. TSQL provides the developer with several constructs that can store temporary result sets that are passed…

Database Files & Objects – Part 2

admin

Today, I will be continuing my talk on database files and database objects that can be viewed through the system catalog views or system stored procedures. A Microsoft SQL Server database is composed of at least two operating system files: a primary data file and a transaction log file. A secondary data files can be used to implement table partitioning or storage of data on different disks by filegroup. If we want to get a simple list of all the databases on the server, one can execute the sp_helpdb system…

Database Files & Objects – Part 1

admin

I am currently reading Kalen Delany and others book on SQL Server 2008 System internals. If you have not read this book from cover to cover, you should. It has a wealth of knowledge about database engine details. To demonstrate key ideas from the book, I am going to expand on the [MATH] database that contains PRIME numbers. The trial division algorithm inside this database uses a brute force method for calculating prime numbers. This article will focus on files and objects that can be viewed through the system views,…

Basic Training – Data Types – Part 6

admin

I am continuing my series of talks on fundamental topics like data types. I am proud to be a United States Army Reservist (USAR) Veteran. Just like boot camp I went to so long ago, I am going nick name the series BASIC TRAINING. The most basic unit of any database is a TABLE which consists of COLUMNS. A vital decision during the initial database design is to choose the data types that will capture the information you want in the least amount of space. Today, I am exploring binary…
