Avoiding redeclaration for transactions in Xquery -


given: 

let $name := '751-1500'     return xdmp:node-delete(doc(concat('/', $name, '.xml'))//foo);  let $name := '751-1500' return xdmp:node-delete(doc(concat('/', $name, '.xml'))//bar);  let $name := '751-1500' return xdmp:node-delete(doc(concat('/', $name, '.xml'))//baz);

how can avoid having redeclare $name?

using separate transactions i'm not sure there nice way this. can declare variable external. still have declared multiple times, have assign once when called via xdmp:invoke (or xdmp:eval):

declare variable $name xs:string external ; xdmp:node-delete(doc(concat('/', $name, '.xml'))//foo);  declare variable $name xs:string external ;     xdmp:node-delete(doc(concat('/', $name, '.xml'))//bar);  declare variable $name xs:string external ; xdmp:node-delete(doc(concat('/', $name, '.xml'))//baz);

then can call module multiple times using invoke different values:

xdmp:invoke('delete-nodes.xqy', (xs:qname('name'), '751-1500')), xdmp:invoke('delete-nodes.xqy', (xs:qname('name'), '751-1501')), xdmp:invoke('delete-nodes.xqy', (xs:qname('name'), '751-1502'))

if don't want module, wrap in function accepts $name param , uses xdmp:eval instead.

Java, Hibernate, MySQL - store UTC date-time -

i saw here on few related questions (like this one , of course, this one )... essentially, want store date-time utc, , let application user choose time zone wants display date-time in. since seems date-time fields affected underlying jdbc driver, wonder if acceptable way go storing utc date-time: set both mysql , application server machine utc time zone (no need separate) both mysql , jvm should pick underlying system time settings (if not instructed otherwise) use datetime table columns on mysql side use java.util.date corresponding mapping on hibernate side (i guess java.sql.timestamp used too) let application worry interpreting date-time fields - i.e. let user choose preferred time zone is ok? edit clarify - here meant refer timestamps created strictly on server (e.g.date-time of record creation). application server instantiates date objects (new date() equals current date-time on server, , time zone agnostic). if client user wants supply date searching/filte...
