  2. Lesson A Objectives • Understand Reports Builder report styles • Use the Report Wizard to create a report • Configure the appearance of a report • View a report in a Web browser • Create a master-detail report • Create a custom template • Apply a custom template to a report A Guide to Oracle9i

  3. Introduction to Reports Builder Database Reports • Reports Builder allows developers to distribute reports as: • Web pages • .pdf files • Printed • And other formats • Layout styles include: • Tabular • Form • Mailing Label • Form Letter • Matrix A Guide to Oracle9i

  4. Sample Matrix Report A Guide to Oracle9i

  5. Using the Report Wizard to Create a Report • Basic steps using Report Wizard: • Specify the data that the report displays • Select the report style • Configure the report properties and layout A Guide to Oracle9i

  6. Paper Design Window A Guide to Oracle9i

  7. Modifying the Report Appearance • Use Reports Builder environment to modify the report appearance and customize the report features • Paper design window shows how report appears on paper • To view as web page • preview paper design as web page • Make sure form displays correct values before editing design • Use the Paper Design window to change fonts, item sizes, etc. A Guide to Oracle9i

  8. Reports Builder Object Navigator A Guide to Oracle9i

  9. Viewing the Report as a Web Page • To preview a report as a Web page: • Click the Run Web Layout button on the Reports Builder toolbar • Creates the Web page source code for the report • Displays as Page Design view without any formatting changes • To view formatting changes: preview the report using either a Paginated HTML or a Paginated HTMLCSS format A Guide to Oracle9i

  10. Viewing a Report as a Web Page A Guide to Oracle9i

  11. Creating a Master-Detail Report • Report can display master-detail data • SQL query must retrieve master and detail data • Use Groups page to define master and detail groups • Two report styles: • Group left: master records appear on the left side of the report; detail records appear in columns to the right of the master records • Group above: detail records appear below the master records • Place column names in Levels on Available Columns page A Guide to Oracle9i

  12. Example Grouped Report A Guide to Oracle9i

  13. Creating Groups/Levels A Guide to Oracle9i

  14. Report Templates • Custom templates store common formatting information such as: • Font • Background color • Graphics • Stored in .tdf file • Use Paper Layout Template Editor to edit A Guide to Oracle9i

  15. Paper Layout Template Editor A Guide to Oracle9i

  16. Applying Custom Templates to Reports • Templates are applied to reports using Reports Wizard Template page • Use Template file specification option button to select a custom template • Or register template as a predefined template: • Modify the Developer user preferences file, so the custom template appears in the Predefined Templates list • Copy the template file to the Reports Builder templates folder A Guide to Oracle9i

  17. Lesson B Objectives • Understand the components of a report • Modify report components • Modify the format of master-detail reports • Create parameters to allow the user to customize report data A Guide to Oracle9i

  18. Report Components • Data Model • Specifies the data that the report displays • Paper Layout view • Displays the report components as symbolic objects • Report frames • Group related report objects A Guide to Oracle9i

  19. Data Model Window A Guide to Oracle9i

  20. Data Model Window • Modify data model properties using Property Inspector • Can modify the report’s SQL query • Create a group filterto limit the number of records that a report query retrieves • Assign a value to the Filter Type property in the report record group’s Property Inspector • Faster to limit retrieved values with SQL query where clause A Guide to Oracle9i

  21. Paper Layout Window A Guide to Oracle9i

  22. Report Display • Reports have a header, main section and footer • Frames • Containers for grouping related report objects • Use to set specific properties for a group of objects • Record group • Have corresponding group frame • Encloses a repeating frame and an optional header frame A Guide to Oracle9i

  23. Components of a Master-Detail Report • Master-detail reports: • Display master-detail data • Multiple record groups: master in one, detail in another • Multiple group frames A Guide to Oracle9i

  24. Master-Detail Data Model A Guide to Oracle9i

  25. Master-Detail Report Layout A Guide to Oracle9i

  26. Master-Detail Group Frame Relationships A Guide to Oracle9i

  27. Report Parameters • Specifies how a report appears • Specifies the report’s behavior when it runs • System parameters • Specify properties that control how the report appears in the user display and how the report application environment behaves • Examples: currency symbol, whether the print dialog box opens when the user prints the report • User parameters • Allow the user to select values that specify the data that the report displays • Example: allow the user to select a specific term ID value from a list, and the report would then display class lists for that term only A Guide to Oracle9i

  28. System Parameters A Guide to Oracle9i

  29. User Parameters • User selects from parameter list • Inserted into search condition • To create: • Create the user parameter • Create the parameter list • Modify the report query so it uses the parameter as a search condition A Guide to Oracle9i

  30. Lesson C Objectives • Display image data in a report • Manually create queries and data links • Create summary columns • Create formula columns • Create reports that display formatted data in a Web browser window A Guide to Oracle9i

  31. Displaying Image Data In Reports • Retrieve and display LOB image data on reports • Use Property Inspector to change File Format to Image to display image data A Guide to Oracle9i

  32. Report with Images from the Database A Guide to Oracle9i

  33. Creating Report Queries and Data Links Manually • To create a query manually: • Open the Data Model window • Select the SQL Query tool on the Data Model tool palette • Click in the painting region, and type the SQL query • To create a data link: • Select the Data Link tool on the Data Model tool palette • Draw a link between linked objects • Types of data links: • Query to Query • Group to Group • Column to Column A Guide to Oracle9i

  34. Manually Creating a Query and Data Link A Guide to Oracle9i

  35. Creating Reports that Display Calculated Values • Formula columns • Display values that PL/SQL functions calculate using report data field values as input parameters • Summary columns • Perform summary functions (such as SUM,AVG, or MAX) on report data fields A Guide to Oracle9i

  36. Example of Calculated Values A Guide to Oracle9i

  37. Creating Formula Columns • Formula columns: • Display a value that a user-defined function returns as a result of performing computations on report data values • To create: • Create the formula column in the report Data Model • Write the user-defined function that returns the calculated value for the formula column • Create a layout field in the report to display the formula column value A Guide to Oracle9i

  38. Syntax for Formula Column A Guide to Oracle9i

  39. Creating Summary Columns • Summary columns: • Return a summary value, such as the sum or average, of a series of data fields in a repeating frame • Create summary columns for any report data field using the Totals page in the Report Wizard • Can also create summary columns manually A Guide to Oracle9i

  40. Creating Summary Columns with Reports Wizard A Guide to Oracle9i

  41. Displaying Formatted Reports as Web Pages • Use Oracle9i Application Server to generate reports dynamically • See Figure 7-70 A Guide to Oracle9i

  42. Summary • Reports Builder creates formatted reports using database data • Reports are drawn using the Paper Design Window • Templates can be created to format reports • Reports can be created to display master-detail data • Report columns can be set to display calculations, formulas and summary information • Reports can be generated in paper, pdf, or html format • Dynamic reports are generated using Oracle9i Application Server A Guide to Oracle9i
