Sorting and queries
Learning to sort and use queries in databases is incredibly
useful as it can allow you to pinpoint the exact data you require.
Can you think of examples of where this is used?

Basic sorting
Databases are extremely useful as they allow you to create
tables of related data which can then be searched and
sorted as needed.
Right-clicking on one of the field headings and then
choosing Sort Ascending will put the
data in ascending alpha-numerical order.
Alternatively, you can highlight a field and
click on either of these icons on the toolbar.

Databases are used for searching and sorting vast quantities
of data and producing results that match criteria. To search or
sort a database in this way requires the creation of a query.
To create a query:
Select Queries from the Objects menu. You
can then choose to use the Wizard or Create
query in Design view.
When you are creating queries in design view, you will be able
to select sorting options for multiple fields.
You can also save queries and produce a report
with the data you have obtained.

Creating queries
This query has been set up to sort by age, but within each age
group the results are to be sorted alphabetically by surname.
The top line of the query specifies the fields to be displayed.
The second line
specifies which
table will provide
the data.

The third line
selects if the data
is to be sorted in
ascending or
descending order.
Remember to tick
the show boxes or
your data will not
be displayed.

Advanced queries
Database queries really come into their own when you want
to put together advanced searches.
Imagine you had a database of valued customers. What if
you wanted to find all the customers under thirty, living in
London who spent over a £1,000 in the previous year.
This would take you a long time to find on paper reports, but
with a database query it can be done very simply.
Table name Customers
under 30 in London

Advanced queries
Entering data into the criteria box allows you to be very
selective about what data is returned.
To help with this you can use logical and relational operators.
Logical operators
A forename search for “Pete” OR
(AND, OR and NOT)
“Peter” will return results for anyone
help to create logic
statements for queries. called Pete or Peter.
Relational operators
(=,<,>,=,<=,>=) help
to construct
range statements.

An age search for >=14 AND <= 18
will return all the records with ages
between 14 and 18.
