While reading the JXQ draft specs, I stumbled upon the following query: (pegasus:sql/src/jdbc) fabian% JdbcClient -lxquery Welcome to the MonetDB interactive JDBC terminal! Type \q to quit, \h for a list of available commands auto commit mode: on monetdb-> import schema namespace foo='http://www.foo.com' monetdb=> at 'http://www.fooschema.com'; monetdb=> for $i in (foo:hatsize(1),foo:hatsize(4)) return $i monetdb=> Error: protocol violation, unexpected line: xquery_prepare: missing ';' after module import. monetdb-> Apart from the protocol violation (should be fixed, missing !) I was wondering whether the "at 'http://www.fooschema.com';" part is not supported by the compiler, or whether it may not reside on a new line. monetdb-> import schema namespace foo='http://www.foo.com' at 'http://www.fooschema.com'; monetdb=> for $i in (foo:hatsize(1),foo:hatsize(4)) return $i monetdb=> Error: protocol violation, unexpected line: xquery_prepare: missing ';' after module import. monetdb-> It seems not to matter. Not being an XQuery expert at all, I was wondering if someone could enlighten me on the validity of this statement. (PS: not a simple example from the JXQ draft works in MonetDB/XQuery, because we either don't support external variables, or their syntax is wrong... The notion of "prepared" xquery is quite central in JXQ, I was wondering whether this is available in MonetDB/XQuery, already or not.)
