hello,          thanks for help, but also can u tell me any way to find the cost of final execution plan, m unable to find any option to see what is the actual cost of final execution plan.

The actual cost (i.e., time) to execute a query (plan) is reported when mclient is called with the "-t / --time" option; see also `mclient --help` and/or http://monetdb.cwi.nl/XQuery/Documentation/The-Mapi-Client-Utility.html . As explained in previous posting on this list, the current open-source release of MonetDB/XQuery does not use/have any cost estimation.
