1. Creating Simple and Complex Queries

2. Starter
What does query mean? What does sorting mean?

3. Lesson Objectives By the end of the lesson you will be able to:
Define the key term query
Create queries using appropriate search criteria
Create queries using mathematical operators
Sort data in a query

4. Scenario - Reminder Our school arranges school trips.
Students hand in letters which must be collected and passed on to the school office.
Office staff then enter this information into a database.
The database has been modified to include the tutor group students belong to.
Before we start you need to copy the new database from Dept Share/VLE into your Practical Skills folder.

5. Recap from last Practical Lessons
So far we have:
Created a database structure
Imported data
Edited data types
Created calculated fields

6. Queries A “Query" is basically a "question" that you ask the database.
Static /Simple query = one question
Complex query = two or more questions
Make a Note.

7. Task 1 – Simple Queries
Watch the video from start to end called Creating a Simple Query. This is in the Dept Share.
Use the video to help you create queries for each of the following:
Students with an allergy
Students from HA1
*Note use appropriate names for each query.
3. Under the subheading Query Steps, write a numbered
list of the steps for creating a query.

8. Task 2 – Sorting
Your teacher will now demonstrate how to use the sorting tool.
Modify your query for HA1 to sort the students into alphabetical order by surname.
Create the following query:
Students who have paid a deposit
Sort by the date paid into ascending order.

9. Task 3 – Mathematical Operators
We can use mathematical operators in the criteria field…
Operator
Meaning =
Equal to
>
Greater than
<
Less than
>=
Greater than and equal to
<=
Less than and equal to
Make a Note.
Create a query for people who have paid a deposit on or after 12th March 2012.

10. Plenary – Hands Up! What is a simple query? What is a complex query?
What is sorting?
What are the 5 mathematical operators?
