When I execute:
Cursor newCursor = JDOCursorHelper.getCursor(<results variable>);
newCursor is always null even though there are valid results returned
and there are more in the datastore that fit the query.
Since I am filtering multiple times on the same property, is this
query getting treated as an "IN" query (and therefore not compatible
with cursors)?
If so, is there a way I can get around it?
If not, what did I do wrong?
Query getAllGameDataQuery = pm.newQuery(AllGameData.class,
"this.gameDate == d1 "
+ "|| this.gameDate == d2 "
+ "|| this.gameDate == d3 "
+ "|| this.gameDate == d4 "
+ "|| this.gameDate == d5 "
+ "|| this.gameDate == d6 "
+ "|| this.gameDate == d7");
getAllGameDataQuery.declareParameters("String d1, String d2,
String
d3, String d4, String d5, String d6, String d7");
Map<String, String> args = new HashMap<String, String>();
args.put("d1", dateArray[0]);
args.put("d2", dateArray[1]);
args.put("d3", dateArray[2]);
args.put("d4", dateArray[3]);
args.put("d5", dateArray[4]);
args.put("d6", dateArray[5]);
args.put("d7", dateArray[6]);
//Get only 20 results at a time
getAllGameDataQuery.setRange(0, 20);
// If this servlet is passed a cursor parameter, let's use it
if (startCursor != null) {
Cursor cursor = Cursor.fromWebSafeString(startCursor);
Map<String, Object> extensionMap = new HashMap<String,
Object>();
extensionMap.put(JDOCursorHelper.CURSOR_EXTENSION,
cursor);
getAllGameDataQuery.setExtensions(extensionMap);
}
@SuppressWarnings("unchecked")
List<AllGameData> AllGameDataResults = (List<AllGameData>)
getAllGameDataQuery.executeWithMap(args);
String newCursorString = "";
try{
Cursor newCursor =
JDOCursorHelper.getCursor(AllGameDataResults);
if(newCursor!=null){
newCursorString = newCursor.toWebSafeString();
}
}
