Hi Rashid,
The answer is yes... and I believe that the following code achieves that on
both single and multi tier approaches (well it works on multi-tier client
code):
String entity = getContext().getEntityResolver().lookupObjEntity(
persistentClass).getName();
HashMap map = new HashMap();
map.put("entityName", entity);
addWhereClause(map);
NamedQuery query = new NamedQuery("EntityCount", map);
Map row = (Map) getContext().performQuery(query).get(0);
return ((Number) row.get("C")).intValue();
Then, in the modeller create the following Query, in this case it is
called "EntityCount":
SELECT #result('count(*)' 'int' 'C') FROM $entityName $whereClause
Hope that helps,
