Hello, I am trying to run some Xqueries from command line but I am getting the following error: $ java -cp "C:\Program Files\BaseX\BaseX.jar" org.basex.BaseXClient -Uadmin -Pa dmin -c"open dbname;xquery <results>{ let $total:=count(//callRecords/*) return <t otal>{$total}</total>}</results>" Error: Stopped at line 1, column 30: [XPST0003] Expecting "}", found ":". If I run the query from the GUI it runs correctly, but here I am always getting this error. I tried running other dummy queries that work in the GUI but here I get an error like this: $ java -cp "C:\Program Files\BaseX\BaseX.jar" org.basex.BaseXClient -Uadmin -Pa dmin -c"open dbname;xquery let $total := count(//callRecords/*) return $total" Error: Stopped at line 1, column 23: Syntax: XQUERY [query] Evaluate XQuery. Any idea of how to solve this? Is it possible to use let in queries from command? Thanks in advance for your help. Hector
