Query tuning is the process of analyzing query performance and making changes to improve performance. To tune a query, you can use the SQL Server Management Studio Query Analyzer to capture query execution plans
We need to be careful with the results; even though a query can have a maximum average run time, if it runs only once, the total effect on the server is low compared to a query which has a medium average run time and runs lots of times in a day. #3 Fine Tuning Queries The fine...
Performance is a big deal. No matter if we’re talking about applications in which users click buttons to display data or if we’re writing a query directly into let’s saySQL Server Management Studio(SSMS). Nobody likes to click a button, go get a coffee, and hope the results are re...

The next time a query comes in and has a similar Where clause or path to the data, SQL Server will reuse the query plan for performance game. There are of course aging algorithms that will remove old query plans from the cache, but this is internal stuff and, as always, SQL S...
How Does SQL Server Work? Indexes Like other relational databases, SQL Server allows you to create indexes. These can potentially speed up read operations because—depending on the nature of the query—index searching is typically faster than searching each table row individually. The SQL Server qu...
While this can be caused by a multitude of factors, it is more often than not caused by a bad query. While everyone always hopes to recover through some quick config tuning, the real fix is to identify and fix the problem query. Sure, we can generally alleviate some pain by throwing ...

query optimizer has to retrieve the data. While this basic example runs quickly, implicit conversions can dramatically impact the performance of your application. You should ensure all your application code variables match the data types of your parameters in SQL Server to avoid this performance ...
