Hi,
I’ve got records like
XQueries like:
let $a := distinct-values(input()/xrecord/Author)
return $a
do return the expected values. When I replace “Author” in the xquery with any other field (i.e. “sourcetype”) Tamino returns:
ino:code=“INOXQE6301”>Runtime type exception
Does anyone have a suggestion what went wrong? All fields are defined similar in the schema.
Thanks for an answer,
Stephan
Hi Stephan,
Have you checked what the “explain” option gives for this query ?
Can it use indexes etc or does it do a “tablescan” ?
Different indexing could be the explanation between the field…
In any case - this does look like a very graceful answer to a polite xquery 
I can see that some runtime-errors have been fixed in PL8 from July, are you running latest PL ?

Hello Finn,
oh, you’re absolutely right. I should have checked that before. When I define an index on the fields polite xqueries get polite answers 
Thank you very much.
Kind regards,
Stephan
