I have two queryDataSet, what I want to do is loop one
querydataset and for each row, find the corresponding row in
another queryDataset by a common fieldNames, the question seems
simple, but I don't know how to find a row based on a
fieldName. what I find is goToRow(int row), which seems not
suitable for my need (I need the parameter is a fieldName,
string, not row), is there any method?

Thx!!

Here's some code I pulled out of one of my applications:

DataSet gamesDataSet = mainDataModule.getGamesDataSet();
DataSetView gamesDataSetView = gamesDataSet.cloneDataSetView();

try {
DataRow locateRow = new DataRow(gamesDataSetView, new String[] { "eventKey" });

locateRow.setInt("eventKey", eventsDataSet.getInt("eventKey"));

if (!gamesDataSetView.locate(locateRow, Locate.FIRST)) {
gamesDataSetView.close();
gamesDataSetView = null;
}
}
catch (DataSetException ex) {
gamesDataSetView.close();
throw ex;
}
