When you are working with large
scale data, then even the most minor change made by you in the database may
have a dramatic impact on the performance. The impact could be both positive
and negative. In such situations, SQL performance tuning can be an incredibly
challenging task.
Typically, a Database Administrator
or DBA handles most of the SQL performance tunings in mid-sized and large
companies. However, most of the companies with DBAs strive hard to work in sync
with developers. The problem-solving modes of both the teams are different
which often leads to conflict among the co-workers.
As a result, companies have to
depart them and let them work separately with their own techniques. However,
for better performance tuning, both teams need to work together for an
effective result. In this blog, we are going to learn three important tips that
will help in tuning SQL
performance tuning.

Three Experimented Techniques for SQL Performance Tuning
Without much ado, let us look at these three
important tips to tuning:
Tip
1: Generation of an Actual Execution Plan
An SQL Server Management tool is crucial for generating graphical execution plans as well as for creating indexes. One can generate the actual execution plan only after the queries run. But the question arises- how will you generate it?
You need to simply click on ‘Include
Actual Execution Plan’ or CTRL + M before running your query. Later on, a new
tab will appear namely ‘Execution Plan’ where you will find a missing index.
Ultimately, you have to right-click and select the ‘Missing Index Details’ in
the execution plan and you’re all done.
Tip
2: Indexing
Through indexing, you can
effectively tune your SQL performance. However, most of the developers often
neglect it during the development process. An index is a data structure that
provides efficient access of ordered records and random rapid lookups to
upgrade the speed of data retrieval operations.
It implies that once an index has
been created, you can sort or select your rows even faster. Furthermore,
indexes also define the unique index or primary key to ascertain no other
columns hold the same value.
Tip
3: Discover Slow Queries with SQL DMVs
DMV (Dynamic Management Views) are
built into SQL Server and is one of the most significant features of SQL
Server. They are in dozens and render a wide range of information pertaining to
various topics. Several DVMs offer data about execution plans, recent queries,
query stats, and more. These data can be combined together to obtain some
astonishing insights.
Final
Thoughts
So, for the next time, you need to
improve the SQL performance tuning, you will have these three essential
techniques at your fingertip. However, there are several other tips as well
that can upgrade to the performance of your SQL server.
But before opting for any SQL tuning
products, you must ensure the type of SQL performance functionality the product
has built-in. There are several SQL tuning products available in the market but
they aren’t useful to you until you have an in-depth knowledge of the same.
Tosska provides a
one-button-solution tool to automatically tune the SQL statements without the
need for users’ intervention. It offers various other tools to cope up with
different issues related to SQL
performance tuning. Therefore, you must look once into its products.
