Specifying Parameter Values
When you run or schedule a report via API, if the report contains parameters, you need to specify the parameter values. This topic is about setting parameter values.
Select the following links to view the topics:
Setting Values of Multi-value Parameters
Take the following example to set values to a multi-value 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:
- 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. - Add the class path into the class path of your implementation of running or scheduling the report such as DemoParameterRunReport.
- In DemoParameterRunReport, replace the way of setting static parameter values and instead set dynamic values of the required parameters 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 as follows:
props.put(APIConst.TAG_PARAM_PREFIX + "PToday", APIConst.TAG_PARAM_GEN_PREFIX + "MyParameterGeneratorImpl";
