CFDJ Feature: Creating Subreports with the Report Builder in ColdFusion MX 7

With ColdFusion MX 7, you can use subreports to show more detailed reporting

  1. Double-click the following fields: Emp_ID, FirstName, LastName, Dept_ID, Salary, and Contract.
  2. For Dept_ID, deselect the Output check box so that this field will not actually be displayed as part of the report. It will, however, be part of the SQL Where clause.
  3. In the Dept_ID row, under the Condition column, select Where from the pop-up menu. From the Criteria column, select = #CFvariable#. Note that this is the unquoted option, not the "#CFvariable#" option. Selecting these options creates or changes the SQL query in the panel below.
  4. In the SQL query panel, modify the Where clause. Replace the value, CFvariable, in the Where clause with param.DeptID. Do not delete the pound signs around the variable. By changing the variable, the query references the input parameter for the report that you will create later. Your query appears like that shown in Figure 5.
  5. Click the Test Query button, enter a test value of 1 and click Run. The query will return seven results. Close the results window.
  6. Click Save. Click Next on the Define Group Reporting dialog box.
  7. On the Report Layout dialog box, make sure that you have only selected the Grid option. Click Next.
  8. On the Report Layout page, select the Only Detail Band option. Deselect the Create Totals for Numerical Fields option. Click Next.

    Note: The report will run properly if you select the Default option at this point.

  9. Click Next on the Report Theme dialog box.
  10. Enter Employees by Dept for all three title fields on the Report Name dialog box. Click Next.
  11. Click Next on the Subreport Binding dialog box.
  12. For the Subreport Filename, save it in the same directory as the main report. Name this report Employees. Click Next.
  13. Click Finish.
  14. Save the Employees report.
  15. In the Employees report, open the Fields and Parameters panel. If it isn't open already in the lower right corner of the Report Builder, select Window > Fields and Parameters.
  16. In the Fields and Parameters panel, click the Input Parameters option once and click the plus (+) button to add an input parameter. The Add Input Parameter dialog box appears.
  17. Enter DeptID for Name. Select Integer for the data type. This parameter corresponds to the param.DeptID referenced in the Where clause of your SQL statement you typed in earlier. Click OK.
  18. Save the Employee.cfr report and preview by pressing F12. Enter 1 for the DeptID parameter; your report appears.
  19. Toggle to the Company-Departments_v2.cfr report.
  20. Click the Subreport component once to select it. In the Properties inspector, click the plus (+) sign to expand the Data property. Click Subreport Parameters once to select it.
  21. Click the ellipses to add a parameter. The Subreports Parameters dialog box appears. Click Add.
  22. Enter DeptID for Name and select #query.Dept_ID# from the pop-up list (see Figure 6).
  23. Click OK, and then click OK again to close the Subreport Parameters dialog box.
  24. Save the Company-Departments_v2 report.
  25. Preview your report (press F12). It appears similar to the report in Figure 7.
Congratulations! You have successfully created a subreport from the main report.

Where to Go from Here
This article described two different techniques for linking subreports to main reports. You can bind the parameters property in the subreport component, which will match the input parameters of the subreport itself to link reports. I have found that creating the subreport through the Subreport Wizard, the second example, has proven to be easier and reduced the guesswork in formatting the subreport with the main report.

I hope that after following the sample reports and creating subreports you can appreciate how easy it is to develop and link subreports to a main report. I believe this will help you get up and running with the ColdFusion Report Builder so you can create reports and link subreports with little trouble.

When talking IoT we often focus on the devices, the sensors, the hardware itself. The new smart appliances, the new smart or self-driving cars (which are amalgamations of many ‘things'). When we are looking at the world of IoT, we should take a step back, look at the big picture. What value are these devices providing. IoT is not about the devices, its about the data consumed and generated. The devices are tools, mechanisms, conduits. This paper discusses the considerations when dealing with the...
