Specifying Parameter Values

You need to specify the parameter values when you run or schedule a report via API, and if the report contains parameters. This topic describes how you can specify values to Multi-valued Parameters and specify dynamic parameter values.

This topic contains the following sections:

• Setting Values of Multi-valued Parameters
• Setting Dynamic Parameter Values

Setting Values of Multi-valued Parameters

Take the following example to set values to a multi-valued parameter Customers_Country:

String[] a = {"USA", "Canada"};
props.put(APIConst.TAG_PARAM_PREFIX + "Customers_Country", a);

If you want the parameter to use all its values, take the following:

props.put(APIConst.TAG_PARAM_PREFIX + "Customers_Country", new String[]{APIConst.MULTIPLE_ALL_VALUE});

For the API code of running a report, see APIDemoRunReport.java in <install_root>\help\samples\APIServer.

Setting Dynamic Parameter Values

You can specify dynamic parameter values by implementing the ParameterGenerator interface.

To set dynamic parameter values to a report:

1. Create a class MyParameterGeneratorImpl to implement the ParameterGenerator interface. See the API demo DemoParameterGenerator.java in <install_root>\help\samples\APIParameter for an example of implementing the ParameterGenerator interface.
2. Add the class path into the class path of your implementation of running or scheduling the report such as DemoParameterRunReport.
3. In DemoParameterRunReport, replace the way of setting static parameter values and instead set dynamic values of the parameters you want in the report. Take the parameter PToday for example:

   First disable or delete the line:

   props.put(APIConst.TAG_PARAM_PREFIX + "PToday", "2007-5-21");

   and then add a line:

   props.put(APIConst.TAG_PARAM_PREFIX + "PToday", APIConst.TAG_PARAM_GEN_PREFIX + "MyParameterGeneratorImpl";
