[basex-talk] Reg : Group By Clause

Dear Team ,

I am following the below steps to execute my XQuery 1) I am Created collection with the MyFile.xml 2) I am running the query which is in attached file(query.txt) on the above collection 3) I am Grouping the C4 element for Grouping 4)I am running this query in java

Java code : new XQuery(query).execute(context,fileoutstream);

Query running properly when I am not using the group by clause

Problem : If I use the group by ,exception is coming like out of main memory,can you please tell me Is their any alternate to reduce the memory when using group by

Thanks & Regards Chandra Sekhar
