Hi All,
Hope everyone is doing good. I am currently trying to copy an entire folder from the source location to a destination location. I have tried rename but its too expensive from time response stand point when the schema size is too large. To go around the problem I am trying to run the xquery using db:store (). But db:store doesn’t seem to work on folders. So I am wondering if there is any other efficient way ( apart from rename and db:store) which will work on the folder. I need to copy the entire folder from source location to destination and it may have a hierarchy of sub-folders in it. Any help on that is really appreciated!
Thanks,
Bhushan

How did you proceed so far?

Hi Bhushan (cc to the list),
So you are exclusively working with binary resources, right? In that case, a query like the following one can be used:
let $db := 'db'
let $src-path := 'src/'
let $trg-path := 'trg/'
for $src in db:list($db, $src-path)
let $trg := $trg-path || substring-after($src, $src-path)
return db:store($db, $trg, db:retrieve($db, $src))I have added a slightly revised version of this query in our Wiki [1].
Hope this helps,
Christian

I am currently trying to use the db:store(source, destination, file) in an xqeury. This approach works well when the source is a file but doesn’t work when the source is a folder. I need something that will move/copy and entire folder and not just a file. > > > > > > On 2/13/17, 1:46 PM, "Christian Grün" <christian.gruen at gmail.com> wrote: > > Hi Bhushan, > > > Hope everyone is doing good.

Written for BaseX 8.6. BaseX may have changed since: please check the current documentation.
