1
either of two other things (an OR relationship between them)
just one thing that stands alone.
2
I am going to write an SQL statemnt, so I go into query and ADD the table. Then I go to the icon and select SQL view.
3
I am writing the SQL here in the screen that comes up.
I copied it here so it was more readable. I am looking for a list of fields from booktable with two criteria in an AND relationship.
5
I went back and change the AND to an OR in the SQL query and this is the result.
6
then either the year has to be greater than 2002 or the publisher has to be Course.
7
Again this is the copy that I put in notepad to make it more visible.
8
get resoved first.
9
publisher = Course.
10
flowchart is easier.
11
Here I asked about the things in the AND relationship first, this means that if I get a NO to either, I have to ask about publisher.
14
If I go back to query view, I can see that Microsoft created the user interface query from my SQL.
15
This is the one where edition had to be 2 and either of the other things - the parenthesis was used to group.
