Question

Suppose:
I have a single table that holds the book ID, student ID and date of every book checked out this year.

How can I count the number of books that each student has checked out?

I currently have +4000 students and +60000 check outs.

All this information is stored on a MySQL server AND I have a Open Office Calc table with this information. I also have ACCESS97 installed, so I guess I could use some VBA code to do this.

The only way I can think of doing this is making a gigantic LOOP statement with Access to count everything and copy whatever meets certain criteria.

But I’m pretty sure I can use some SQL commands via Access that would make this task a little bit faster.

Answer 1

Try this SQL command in Access:

SELECT student_id, count(book_id) AS num_of_books
FROM myTable
GROUP BY student_id
