Hello, I have a problem with a query.
The query is this:

let $añoMin := min(/nacimiento/nacido/fecha/anno)
let $meses := /nacimiento/nacido/fecha[anno = $añoMin]/mes
let $mesMin := min($meses)
let $diaMin := /nacimiento/nacido/fecha[anno = $añoMin and
mes = $mesMin]/dia[1]/text()
return
<nacimiento>
<nacido>
<atributo>nacido antes de</atributo>
<fecha>
<dia>{$diaMin}</dia>
<mes>{$mesMin}</mes>
<anno>{$añoMin}</anno>
</fecha>
</nacido>
</nacimiento>

The problem is that when I execute the query, Excelon Stylus Studio closes and the typical
error message of Windows XP apperas.
I have tried to execute the XQuery with several versions of stylus studio but it always
crashes. Anybody knows the cause of this problem?

Thanks.

Hi Jose,
I have tried running the query using version 5.3 and it did
not crashed, but I didn't have the source XML file.
Can you try running the query using an empty scenario?
If it doesn't crash I would like to see the XML source you
are using; if it still crashes it could be because of the "ñ"
character, expecially if you wrote the query file using a
different editor than Stylus (this because Stylus assumes the
query file to be saved in the UTF-8 encoding).
In the latter case you could try either saving the query in the
original editor using UTF-8, or rewrite it inside Stylus Studio.

Let me know how it works,
Alberto

Hello again, I still have the problem with the Query.

I have tried running the query changing the 'ñ' character by 'n' and it crashes, so it is not the error.
I have also tried running the query using an empty scenario and it doesn't crash.
This is the source XML:

<nacimiento>
<nacido>
<atributo>nacido antes de</atributo>
<fecha>
<dia>05</dia>
<mes>08</mes>
<anno>1667</anno>
</fecha>
<fuente>c:\oshi\doc\notarial\arrendamientos\3160p-05-08-1667-04-211r.214v.xml</fuente>
</nacido>
<nacido>
<atributo>nacido antes de</atributo>
<fecha>
<dia>12</dia>
<mes>09</mes>
<anno>1661</anno>
</fecha>
<fuente>c:\oshi\doc\notarial\arrendamientos\2741p-12-09-1661-04-279r-282v.xml</fuente>
</nacido>
</nacimiento>

I have no idea about the cause of the error, because, actually, there is no error message, only the Stylus studio is closed. Can you help me? Thanks

Hi Jose,
thanks for the XML fragment; now I can reproduce the crash, that is caused
by invoking the min() function on a sequence containing a single item.
A fix for this bug will be available in the next update of Stylus.

Thanks again for the bug report,
Alberto

Thanks for your help Alberto.
Why it doesn't crash with the 'max' function?
How could I do it with this version? (I'm using v5.3)
Do you konw when will the new version be available?

Thanks again.

The implementations for the min() and max() functions share almost the same
code, but the bug was in a piece of code only used by min().

You can workaround the bug by making sure that min() is not invoked with
just one argument, like changing

let $mesMin := min($meses)

into

let $mesMin := min(($meses,999))

>Do you konw when will the new version be available?

This is the first bug we found after bl179g was made available, so it's
still too early to guess when bl179h will be out.
