i won't give up, i won't let you down.


queries can be an "and" query or an "or" query.
"and" - both conditions must be true
"or" - at least one condition must be true
here are some answers to some questions about some query.. and wasn't that vague

Question 11. What sort of information has the query selected? all information that matched the query, for example in the picture above shows all the people who's postcode is 2010 in my database.
Question 12. We can alter any query as follows... What sort of information has this second query selected? It goes into further detail, basically meaning that the people in the database will have more specific details in common.
