How to modify a Crystal Report to use ADO instead of ODBC

Crystal reports which currently connect to an ODBC data source can be modified to use an ADO RecordSet:

  1. In the EMu module from which the Crystal Report is run, click Reports on the Home tab of the Ribbon to open the Reports box:


  2. Select the Crystal Report in the list and view the properties for the report by selecting .

    In this example we select the List (A4) report.

  3. In the Report Properties box, select Crystal ADO Report from the Type drop list:

    Report Type

    The fields for this report are:

    Two tables are generated in this report.

  4. Click OK and run the report.
  5. The ADO record set will be created and an error will display (the report is looking for a .csv data source).

    We now need to modify the Crystal Report.

  6. Click OK to close the error message and again display the Report Properties for the Crystal Report you are modifying (Step 2 above).
  7. Click Download to save the report locally and open it in the Crystal Report Designer.
  8. Select Database>Set Datasource Location from the Menu bar.
  9. The Set Datasource Location dialogue will display:

  10. In the Replace with pane, expand Create New Connection and then expand ADO.NET (XML).
  11. In the ADO.NET (XML) box, locate and select the xmldata.xml file created when the report was run by clicking the ellipsis beside File Path, e.g.:

  12. Click Finish to close the ADO.NET (XML) box and return to the Set Datasource Location box:

  13. Next we map fields from the old ODBC data source to the new ADO RecordSet. In this example there are two tables to map and one sub-report.

  14. To map the old ODBC Catalogue fields to the new Catalogue table, click e_csv in the Current Data Source pane and then click the row table in the Replace with pane.
  15. The Update button will be enabled:

  16. Click Update to display the Map Fields box:

    Fields with the same name are mapped automatically:

  17. Uncheck the Match type check box to reveal more fields in the Unmapped Fields pane:
  18. Complete mapping fields in the Unmapped Fields pane.
  19. In this example we map ecatalogue_key to ecatalogue_key and irn to irn by selecting both fields to map and clicking Map.

    As they are mapped, fields are moved to the Mapped Fields pane:

  20. When all fields are mapped click OK to return to the Set Datasource Location box.
  21. Repeat the mapping process for all fields (in this example, mapping fields in the Subreport CreatorD_csv to the ADO CreatorDetails table).
  22. When all fields have been mapped in all tables click Close to return to the Crystal design window.
  23. Refresh (F5) the report.
  24. Save the report.
  25.  The final step is to save the modified report back to EMu:
    1. In EMu, repeat Steps 1 and 2 above to display the Report Properties box for the report:

      Report Type

    2. Select Upload, locate the report file you modified and saved and save it back to EMu.

    The Crystal ADO Report can now be run.
