[MonetDB-users] How could I run a set of XQuery in a batch?

Hello, everyone May I ask you how to run a set of XQueries in a batch? I am using MonetDB v4.22.0 on Redhat Linux. I have a set of XQueries. I want to run them against a single xml document and collect the running time. Currently I am only able to submit one XQuery at a time at the mclient commandline. Is there anyway for me to send all my XQueries in a batch and get the total running time? I also have another question. Does MonetDB handle multi-query optimization? I mean if more than one query have common subexpressions, will MonetDB evaluate them just once? Thanks in advance. Chinyi
