Hi, the pf:recursion-depth function has nothing to do with the errors you are getting. The problem is that your query is too long with too many operators and the compiler runs out of space for recursive calling the function that creates the algebraic tree. lefteris On Sun, Mar 1, 2009 at 9:09 PM, Lazaros Koromilas wrote:

First of all thank you for the quick reply,

I have compiled MonetDB on FreeBSD 7.0.

An xquery code snipet is here: http://pastebin.com/m50d9c7fb

where <xpath> are very simple auto-generated xpath queries using only child axes; one could see them as unix paths.

What about the `pf:recursion-depth' option?

Thanx again, Lazaros.

Hi,

It looks like you have hit the limit of the query size that the MonetDB/XQuery compiler can handle (i.e., optimize and compile a plan). What platform are you using? Windows or Linux? Can you share with us the query that you are trying to run?

The -G option does not make any difference because by default the algebra is enabled.

Also I would suggest to upgrade Monet as soon as the new release is out, because there were some fixes regarding this issue.

Kind regards,

lefteris

Hi all,

We are trying to annotate some XML data with MonetDB/XQuery. For this I run some big queries, that contain unions of many Xpath expressions (say 100).

I get the following error: ERROR = !fatal error: aborted too deep recursion

Tried to use the option declare option pf:recursion-depth "<number>"; I see no difference in bahaviour. I also call mclient with -G, though I don't know if it's needed.

MonetDB Server is v4.26.2 and default back-end is 'algebra'.

Any help with this?

Thank you, Lazaros.
