The LIMIT clause takes on two formats: • LIMIT n, m • LIMIT n The first format tells the query to return just m rows (that is, limiting how many rows to return) starting from row n. The second format simply tells the query to return the first n rows which satisfy the given conditions. The first format definitely provides us with more flexibility, but, unfortunately, neither the second nor the third method allows us to take advantage of this format (due to the way that it automatically constructs the query for us), while the first format (the raw SQL query) can execute any valid SQL query.
And so the output from running this Activity is as follows: And voila! We quickly see that Students 1, 2, 3, and 5 were all enrolled in CS106A. However, after filtering by grade 11, we see that Student 3 is the only one signed up for CS106A in grade 11 – poor George. println("STUDENT " + sid1 + " IS ENROLLED IN COURSE " + cid); } } } This time around, we first ask for all the classes that Student 1 (myself) is enrolled in. But oh no! Something happened to Math51 this quarter and so it was cancelled!
However, we'll see in the next chapter that by mastering more advanced SQL query concepts, we can enjoy both a substantial performance boost as well as a substantial memory boost in our application! [ 42 ] SQLite Queries In the last chapter, we kicked our database building up a notch – transforming a simple schema involving just one, lone table, into a complex schema involving three interdependent tables. And now that we have a solid foundation in developing custom SQLite databases for Android, it's time to put the icing on the cake.
