Before you keep reading...

Runestone Academy can only continue if we get support from individuals like you. As a student you are well aware of the high cost of textbooks. Our mission is to provide great books to you for free, but we ask that you consider a $10 donation, more if you can or less if $10 is a burden.

Before you keep reading...

Making great stuff takes time and $$. If you appreciate the book you are reading now and want to keep quality materials free for other students please consider a donation to Runestone Academy. We ask that you consider a $10 donation, but if you can give more thats great, if $10 is too much for your budget we would be happy with whatever you can afford as a show of support.

Advanced Practice Problems - Mixed-up Code

Let’s practice what we have learned about SQL.

In the grades table:

Create a SELECT statement to retrieve the student_id, test_name, and english for all entries whose english value is lower than 60 and math value is higher than 90.

--blocks-- SELECT student_id, test_name, english FROM grades WHERE english < 60 AND math > 90 english < 60 & math > 90 GET TABLE

In the grades table:

A student completed an extra assignment and got some additional points.

Create an UPDATE statement to change the entry with a student_id of 1 and set the math score for the test_name of final to 90.

--blocks-- UPDATE grades SET math = 90 WHERE student_id = 1 AND test_name = "final" LET student_id = 1 AND test_name = final CHANGE grades

In the grades table:

One test was too difficult so the instructors decided to give everyone extra points.

Create an UPDATE statement to add 10 points to the english score of the entries with a test_name of midterm

--blocks-- UPDATE grades SET english = english + 10 WHERE test_name = "midterm" test_name == "midterm" WHEN

In addition to the grades table:

there is also a students table:

Create a SELECT statement with a JOIN to: select the test_name and math from the grades table and name from the students table, where the student_id in the grades table is the same as the id in the students table.

--blocks-- SELECT grades.test_name, grades.math, students.name FROM grades JOIN students ON students.id = grades.student_id ON students.id = grades.id WITH students GET

In addition to the grades table:

there is also a students table:

Create a SELECT statement with a JOIN to: select the date and name from the tests table and student_id from the grades table, where the test_name in the grades table is the same as the name in the tests table.

--blocks-- SELECT tests.date, tests.name, grades.student_id FROM tests JOIN grades ON grades.test_name = tests.name date, name, student_id JOIN ON
