借宝地问个面试中的sql的问题。
We have two tables, students (student ID, student name, student age, student
zip) and courses (course name, course time) .
The information in the parentheses are the schema.
We want to get how many students enroll all the classes starting at 11:00 AM?
the interviewer mentioned something like many to many join.
the interviewer mentioned something like "dimensionalize" in SQL. I am
wondering who knows any SQL book on this, and can introduce it me?
Thank you so much for your consideration!
