Hello all,
BaseX doesn't seem to like the query below. Any particular reason - it makes sense to me. I'm trying to add items to a DB incrementally to (attempt to) avoid running into out of memory exceptions when cutting a slice of a large DB into a smaller one.
for tumbling window $w in db:open(myDB')//ani:ref-authors/ani:author start at $s when $s mod 50000 = 1 return db:add( 'sliceDB', <index>{$w}</index>, 'somepath.xml' )
Improper use? Potential bug?
