This chapter introduced you to the SELECT statement, logical query processing, and various other aspects of single-table queries. I covered quite a few subjects here, including many new and unique concepts. If you’re new to T-SQL, you might feel overwhelmed at this point. But remember, this chapter introduces some of the most important points about SQL that might be hard to digest at the beginning. If some of the concepts weren’t completely clear, you might want to revisit sections from this chapter later on, after you’ve had a chance to sleep on it.
For an opportunity to practice what you’ve learned and absorb the material better, I recommend going over the chapter exercises.
