When SQL Server executes a query it uses a query plan to determine how to access data and complete the query. SQL Server offers DBAs and developers the ability to see these query plans to assist in query optimization. Without query plans it would be difficult to figure out how to tune and optimize your queries.
One such version of query plans is Graphical Execution Plans which allows you to see a graphical representation of the processing steps of your query to find optimization opportunities.
In this tutorial we will cover:
- An overview of execution plans
- Actual Execution Plans
- Estimated Execution Plans
- Different Types of Query Plans
- Graphical Query Plan Components
- Walk through of different examples
- and how to save plans for future reference.
After you complete this tutorial you will be able to create Graphical Plans, know how to read the plans to assist in tuning your queries.
