SSRS Reports Performance Debugging and Analysis
SSRS provides a very user friendly way to author and deploy reports. These reports can be accessed from different platforms where the reports are deployed - reports manager, SharePoint, stand-alone / distributed applications or programmatically using SSRS SOAP endpoints. Unfortunately, SSRS / BIDS does not provide any high-end debugging tools such as SQL Profiler for analyzing the performance of SSRS reports. In this tip we will look at different ways of debugging and analyzing SSRS reports performance using execution logs and freeware tools.

The default trace in SQL Server - the power of performance and security auditing
Since the introduction of SQL Server 2005, there is a simple lightweight trace that is left running by default on every SQL Server. This provides some very valuable information for the DBA about the running server, but it isn't well-documented. Feodor Georgiev reveals many of the secrets of this facility and shows how to get reports from it.

SQL Server random numerics data generation using CLR
You need to generate random data directly into SQL Server table columns or close to the database engine as variables or expressions. Looking at the SQL Server available functions, you notice that only RAND function offers support for random data generation. Although RAND([seed]) is a built-in function, it can only return a float value between 0 and 1, and has other limitations in regards to seed values. Because your table columns may be of various data types, and each data type may have a lower value and an upper value, you would prefer to create your custom random data generators. This is when SQL Server CLR functions come into play and provide a viable solution.

Naturally Increasing Data Value with Hierarchical Structures
Hierarchical structures have an inherent ability for significant data value increases beyond the data collected. This will be shown to exist in hierarchical structures and even more powerfully in their natural hierarchical processing capabilities. These will demonstrate flexible and efficient ways to increase data value automatically and will be discussed in this article. SQL will be used to perform a wide range of hierarchical processing operations that easily demonstrate these increasing data value capabilities.
