In the majority of cases, the Estimated and Actual Execution Plans are the same. The Actual Execution Plan is how the query ended up being executed. The Estimated Execution Plan is the initial query plan the optimization engine comes up with. Query or execution plans come in three flavors. We've seen query plans in the Query Store, so let's look at them in more detail. To get the most out of this course, you should be familiar with SQL query syntax, SQL data types, and SQL table structure. This course is aimed at database administrators, data engineers, or anyone who wants to learn how to improve database query execution. Understand how database compression can impact performance.Use database file configuration to improve performance.Learn how to design tables to make queries more efficient.Understand how different query types can be used.Use execution plans to see how a query is executed.Learn how the SQL Server engine processes queries.Understand what impacts query performance when using SQL.Using that information, we look at other factors like table and index design that can positively or negatively impact your query execution.įor any feedback relating to this course, please contact us at Learning Objectives This course looks at ways that you can see how the SQL Server engine views your queries and how it intends to execute them. What sets SQL and database programming apart from most other computer programming is the vast amount of data that is regularly dealt with, and how other factors that are not immediately obvious can impact the SQL query code you write. And like other software languages, some ways will be better and more efficient than others. SQL is the language for interacting with databases, and like all computer languages, there are many ways to achieve the right result.
