An Introduction to SQL Server Scalar UDFs

One of the best features of SQL Server 2000 is its user-defined functions (UDFs). UDFs offer many of the benefits of both views and stored procedures, and more. Unlike views, UDFs can take zero or more input parameters and return a scalar value, or can even return a table. Unlike stored procedures, the output of […]

Views in SQL Server

View A view is a virtual table that consists of columns from one or more tables. Though it is similar to a table, it is stored in the database. It is a query stored as an object. Hence, a view is an object that derives its data from one or more tables. These tables are […]

Troubleshooting SQL Server Full-Text Search Problems

Should you have problems with the SQL Server full-text search, review this troubleshooting checklist to help find potential solutions. 1. Check the hardware requirements For SQL Server 7.0, you should have: Alpha AXP, Intel or compatible platform Pentium 166 MHz or higher 64MB RAM or more (recommended) 180MB hard disk space For SQL Server 2000, […]

Optimizing Microsoft SQL Server Reporting Services: Performance and Access Reports from the Execution Log

Overview In our previous article, Execution Log Reporting: Preparation as a Data Source, we began with a discussion about a valuable source of information for performance and auditing analysis, the Report Server Execution Log. We noted that the Execution Log captures data specific to individual reports, including when a given report was run, identification of […]

Optimizing Microsoft SQL Server Reporting Services: Execution Log Reporting: Preparation as a Data Source

What We Will Need to Complete the Series Tutorials To get the most out of the Optimizing MSSQL Server Reporting Services series, we need to have installed Microsoft SQL Server 2000 Reporting Services, together with Microsoft Visual Studio.NET (required to access Report Designer for report creation). Reporting Services ships with MSSQL Server 2000, and many […]

SQL Server 7.0 and 2000 Trace Flags

Trace flags are used to temporarily enable or disable specific SQL Server database functions, allowing you to change default database behavior or to observe hidden database behavior, and will remain in effect until they are either manually turned off or SQL Server is restarted. Keep in mind that most trace flags are undocumented and Microsoft […]

Optimizing Microsoft SQL Server Analysis Services: MDX Optimization Techniques: Optimizing the CROSSJOIN() Function

Overview In this article, we will return to our intermittent examination of various MDX optimization techniques which we have intermingled with other MSAS optimization topics within this series. The function upon which we will focus will be CROSSJOIN(), whose mission it is to combine two sets of dimension members into one. We will discuss how […]

Optimizing Microsoft SQL Server Analysis Services: Enhance Cube Processing Performance with Optimize Schema

Overview In this article, we will explore another tool that MSAS offers for the enhancement of cube processing, the Optimize Schema option. This option can assist us in significantly reducing a cube’s processing time. Optimize Schema attempts to identify unnecessary joins between our fact and dimension tables, and then to remove them. In many cases, […]

Optimizing Microsoft SQL Server Analysis Services: Optimize Query Performance with a Derived Measure

Overview Because a significant part of my practice consists of being called upon to tune MSAS implementations performed by others, I come across the less-than-optimal use of calculated members quite often. As most of us know, calculated members are dimensions or measures (depending upon the designated parent dimension) that are constructed, using a formula, from […]

Optimizing Microsoft SQL Server Analysis Services: MDX Optimization Techniques: Segregating DISTINCT COUNT

Overview In this article, we will continue the examination of distinct counts we began in our previous article, Considering DISTINCT COUNT. Having discussed why distinct counts are useful, and often required, within the design of robust analysis and reporting applications, we described some of the challenges that are inherent in distinct counts. We then undertook […]
