Terry,
Do these parameters just reduce the number of rows or does the schema
change. Because you could always use a beforeOpen script on the data
set to open a URL connection and load up a byte array input stream and
set the appcontext variable:
"org.eclipse.datatools.enablement.oda.xml.inputStream" This will cause
the xml data source to use this data. For example I hard code the
results in the example below.
importPackage( Packages.java.io );
var mystr = "<?xml version=\"1.0\"?>";
mystr = mystr + "<library>";
mystr = mystr + "<book category=\"COOKING\">";
mystr = mystr + "<title lang=\"en\">The test3 Cook Book</title>";
mystr = mystr + "<author name=\"Miguel Ortiz\" country=\"es\"/>";
mystr = mystr + "<sold>10,312</sold>";
mystr = mystr + "<year>2005</year>";
mystr = mystr + "</book>";
mystr = mystr + "<book category=\"CHILDREN\">";
mystr = mystr + "<title lang=\"en\">Everyone is Super Special</title>";
mystr = mystr + "<author name=\"Sally Bush\" country=\"uk\"/>";
mystr = mystr + "<sold>8,222</sold>";
mystr = mystr + "<year>2005</year>";
mystr = mystr + "</book>";
mystr = mystr + "<book category=\"AUTOBIOGRAPHY\">";
mystr = mystr + "<title lang=\"en\">Japanese Greetings</title>";
mystr = mystr + "<author name=\"Taro Yamada\" country=\"uk\"/>";
mystr = mystr + "<sold>7,852</sold>";
mystr = mystr + "<year>2005</year>";
mystr = mystr + "</book>";
mystr = mystr + "<book category=\"WEB\">";
mystr = mystr + "<title lang=\"en\">Query Kick End</title>";
mystr = mystr + "<author name=\"James McGovern\" country=\"us\"/>";
mystr = mystr + "<sold>15,111</sold>";
mystr = mystr + "<year>2006</year>";
mystr = mystr + "</book>";
mystr = mystr + "<audio format=\"CD\" category=\"MUSIC\">";
mystr = mystr + "<title lang=\"en\">Feels Like Home</title>";
mystr = mystr + "<artist name=\"Norah Jones\" country=\"us\"/>";
mystr = mystr + "<sold>9,675</sold>";
mystr = mystr + "<year>2005</year>";
mystr = mystr + "</audio>";
mystr = mystr +"</library>";
JavaStr = new java.lang.String( mystr );
bais = new ByteArrayInputStream( JavaStr.getBytes());
appcon = reportContext.getAppContext();
appcon.put("org.eclipse.datatools.enablement.oda.xml.inputStream", bais);
You could always open the url like:
importPackage(Packages.java.net);
importPackage(Packages.java.io);
dataURL = new URL("http://..");
dataConnection = dataURL.openConnection();
inp = new BufferedReader( new
InputStreamReader(dataConnection.getInputStream()));
//while loop load up bais
inputLine = inp.readLine();
