Module 05 Assignment
Developing Data Queries to Produce Information from Data Sets
Please open the Microsoft Access file Assignment_Mod05.accdb. The data may look
similar to that for Module 01, but they have been converted into a database instead of an
Excel Table.
1. Open the Copy of Patient Information table.
2. List the data fields that you see.
3. Now, open the query named “query on tetanus time”. This query computed the days
and years from last tetanus immunization to hospital admission date. First view the
query in the datasheet view. Next, click on view in the upper left corner and click on
SQL view. You will see the input language needed to pull these fields and compute
the time. There is also a red exclamation mark called “run”. Each time we want to
re-run the query, click on that exclamation mark.
Why re-run a query? Whenever the underlying data are changed or updated, the query can
be re-run to get the current results. This becomes a rapid way of updating results when
dealing with thousands of records instead of a couple dozen.
Fortunately, using Access we do not need to generate much SQL language from scratch.
4. Now, click on View—Design View in the same query. The run symbol mark will be
present, still. The bottom of the query table space now shows the fields selected for
analysis or printing.
5. Which data fields are in the original data table but not in the query? Which fields are
new fields, in the query but not in the original data?
Now, design your own queries:
Query 1
1. Choose Create—Query Design. By double clicking on fields, they are added to the
design view below. Use the copy of patient information table as the data source
2. Develop a query that includes Last name, first name, city, state, DRG, Admission
Date, Discharge date, DRG code, bill amount, and patient birthdate.
3. Select for Discharge date prior to 12/31/2001
4. Sort by last name, Ascending.
5. Save the query as query 1.
Query 2
1. Now we create a query based on an earlier query.
2. Select Create- Query Design again.
3. This time, select the Query on Tetanus time as the input, instead of the original
table.
4. In this new query please show Last name, First name, Admission date, Patient
birthdate, and Years since Tetanus.
5. Sort results by birth-date with oldest patients at the top of the page.
6. There is an issue with the Years since Tetanus field. When a new query is
formulated, the formatting may not copy over. Within design view, select the Years
since Tetanus field. The right hand corner displays field properties. From the format
area there, click to drop down options and choose fixed to show only two decimal
places.
7. Observe the other options for formatting within the query window.
Whenever you run a “cascading” query such as this one, which is based on an earlier query,
remember that to get current information it may be necessary to run the first query, then
run your second query, again.
Be sure to “save as” after each query is run so that the queries save in the database.
