In this article, we will discuss typical errors that newbie developers may face with while designing T-SQL code. In addition, we will have a look at the best practices and some useful tips that may help you when working with SQL Server, as well as workarounds to improve performance.
Sooner or later, a DB administrator would like to have a performance indicator for SQL Server queries. As we all know, running Profiler for 24 hours will lead to a considerable system load and therefore, it cannot be considered an optimal solution for databases used in the 24/7 mode.
So, how can we detect the state of SQL Server queries? How can we run trace for detected query-related problems without the human input?
In this article, I will provide an implementation of the SQL Server performance indicator for queries, stored procedures and triggers, as well as its usage for the trace run. (more…)
In this post, I’d like to take a brief look at the Query Performance Insight — SQL Azure tool which will help you to identify the most expensive queries in your database.

Probably, you are receiving emails from your clients or it takes an hour to create a weekly report instead of a several minutes, or maybe, your application starts throwing exceptions. (more…)
