here is how the sql from the previous question should be, I just don't
know how to do this in access.

The idea is that the user will select a category from a drop down on
the report, I already created this drop down and populated it. What it
should do is update the list of books on the report when the user selects
a new category

we will call the value of this "reportlist.value"

SQL statement 1

SELECT BOOKLIST2.Categories_ID FROM BOOKLIST2 INNER JOIN Categories ON BOOKLIST2.Categories_ID = Categories.ID
WHERE reportlist.value = Categories.Book categories description;

this will give you the category ID based on the category selected. then inorder to get the list of recommendations updated
we need to take this value we will call it SQL result 1 and plug it into this query

SQL statement 2 using result from SQL statement 1

SELECT BOOKLIST2.BOOKS TITLE, BOOKLIST2.Authors, BOOKLIST2.COST OF BOOK, Categories.Book categories description
FROM Categories INNER JOIN BOOKLIST2 ON Categories.ID = BOOKLIST2.Categories_ID
WHERE Categories.Book categories description = SQL result 1;


this is not the best way of doing this but its functional, again access is difficult to work with.

As for your ERD you can just do a screen capture of the relationships screen.

The DB is not set up very well, not sure where you got the sample data from, but basically its not in good 3NF its not
even in good 2NF. The relationships are the best I could make them now with the given table structure.
