Statistics are an important part of the entire process as they help the query optimizer to make the best guesses when accessing data. These statistics include information about columns like: estimated number of rows, the density of pages on disk, available indexes to use, etc. that the query ...
Use SQL Query Analyzer to optimize queries and indexes. Defragment the indexes. Step 1. Use SQL Profiler to Capture Data You can use SQL Profiler to identify queries and stored procedures that perform poorly. SQL Profiler traces provide information about the duration of the query execution, the...

re stored in SQL Server and how to view them. Furthermore, these statistics can be maintained and kept up-to-date to ensure that the Query Optimizer will create the best guesses when fetching data. We also covered examples of different use case scenarios on how SQL Server is accessi...
The fine-tuning of a T-SQL query is an important concept. The fundamental thing to understand is how well we can write T-SQL queries and implement indexes, so that the SQL optimizer can find an optimized plan to do what we wanted it to do. With every new release of SQL Server, we ...

process. The odds are that the queries at the top of your list (either in PMM or the digest report) lack indices. Indexes allow the optimizer to target the rows you need rather than scanning everything and discarding non-matching values. Let’s take the following sample query as an ...
