Summary
As this chapter has shown, the way a T-SQL query is written and submitted to the server influences how it is interpreted and executed by the SQL Database Engine. Even before a single T-SQL query is written, the choice of development style (for example, using stored procedures versus ad hoc statements) can have a direct impact on the performance of the application. As we continue our exploration of the internals of SQL Database Engine query processing and optimization, we will find more and more opportunities to write T-SQL queries in a way that encourages optimal query performance, starting with the next chapter.
