Question

Hi All,
I need to do the batch wise query to product catalog.
For that i have use Query builder but that is giving me repeated items, now i wanted to use RQL using rqlStatement.
Please help me in solving the issue.
Query which i have used using QueryBuilder.
                RepositoryView productView = productRepo.getView("product");          
                QueryBuilder productBuilder = productView.getQueryBuilder();
                Query productQuery = productBuilder.createUnconstrainedQuery();           
                RepositoryItems[] productItems = productView.executeQuery(productQuery,startIndex,endIndex);
Can anybody help me in writing RQL Query to get the specific range of product items from product catalog.

Hi Shakuntala,
There is no executeQuery method defined in RqlStatement Interface, which will accept index for output result.
So As far as I know, what u are trying to achieve is not possible with RQL statements OOTB way.U can consider range of results based on some condition from Repository items.
Please let me know if u find any way to implement it.
Above Query builder should always return different ids if range is not overlapping with previous range.
Please verify that repeated items ids are same or different,
Quoting from API docs:
RepositoryItem[] executeQuery(Query pQuery,
                              int pStartingIndex,
                              int pEndingIndex)
                              throws RepositoryException
    Executes the given query and returns an array of matching RepositoryItems, which are contained within a total potential result set. For example used if one wanted to retrieve elements 50-60 from a query which could return 100 elements.
