12. Skills  page numbers, names, dates  displaying summary calculations grand summary group summary  non-repeating of repetitive data  minimising the number of pages  controlling printing, including page and column breaks.

13. Page numbers pages numbers are displayed by the field titled [Page] and the number of pages in the report by the field titled [Pages] Text can be added to the numbers by enclosing in quotes. For example, =“page “&[Page] or ="page " & [Page] & " of " & [Pages] NB:page numbers are only for multi-page reports.

14. Displaying dates as in queries, the current date can be displayed dynamically by using the calculation =Date() in a text box.

15. Summaries Two types, namely Grand summary Summary (group summary) A Grand Summary appears in a Report Footer or Header A Summary appears in a Group Footer or Header

16. Calculating the Summaries The following functions are typically used Count Sum Avg Max Min

17. Examples of Summaries =Count([Surname]) =Sum([Appearance Fee]) =Avg([Age]) =Max([Mark])

18. Examples of Summaries When placed in the Report Footer =Count([Surname]) will display the number of records that reside in the output

19. Examples of Summaries When placed in a Group Footer =Avg([Age]) will display the average age for each group in the report, eg. each Hair Colour group.

20. Avoiding repetitive data Method 1 - Hiding select the field showing the repetitive data in the Details section of the report choose Properties and set the property Hide Duplicates to Yes set to Yes

21. Avoiding repetitive data Method 2 - Groups click the Sorting and Grouping button and choose a field on which to set the Grouping set the Group Header and/or Footer to Yes set to Yes

22. Minimising the number of pages Keep the detail section as clean and short as possible. Hint Eliminate or minimise the gaps above and below the text boxes.

23. Columns Set these properties in Page Setup Columns

24. when using Group Headers with Columns In Group Header Properties set the property Repeat Section to yes. Hint set to Yes to avoid this problem

25. Controlling printing The printing of data in groups can be controlled by utilising the properties called Force New Page and/or New Column.

26. Sample output

27. Example 2 IT Key Ideas, Dynamic Database Systems, 2002 Print a list of the (full) names of people (alphabetically) without brownish hair colour, displaying the number of people in each hair colour group and also overall (using a minimum number of pages).

30. Producing an output that displays Female Abbott Abram Almond Apponyi … Male Abbery Aitchison Auerbach Auld … where the column headings are the full word version of the gender.

31. Create a new table In the new table create two fields, according to the data dictionary shown Field NameData TypeSize SexText1 GenderText6 Save the table, eg. Genders.

32. Enter data into the new table

33. Creating a lookup list in the many table The data relationship between the Genders and Details tables is one to many, as a Gender has many people, but any person only has one gender. The Genders table is referred to as the one table and the Details table is then referred to as the many table. In this table it is possible to create a Lookup List that allows for easy data entry when entering each new person’s gender.

35. Creating the lookup list Choose Design view for the Details table. Select the Sex field At the bottom, next to General, select the Lookup tab.

36. Change the Display Control to Combo Box. Click on the Build button on the Row Source and this opens a query.

37. Add the Genders table to the query and the two fields to the query close and update the row source.

38. Change the column count to 2 as two fields were placed in the QBE, enter two Column Widths, eg. 1.5, 2.5 enter a total width in List Width, eg. 4 * * * NB: the SQL statement

39. View the table. Click anywhere in the Sex field (column) and click the Lookup arrow.
