declare namespace xs=‘XML Schema’
let $listKeys := distinct-values(
for $b in input()/oDocument [
/oDocument/@type=‘Element’
and /oDocument/@parent = ‘C13ECC62C52B8000’]
/attributes/attribute
where $b/@key=‘C13ED8481ECA0000’ and $b/text() != 123
return $b/@oDocKey
)

return $listKeys

This example works
/*-------------------------------------------------------------------

And here this returns a error

declare namespace xs=‘XML Schema’
let $listKeys := distinct-values(
for $b in input()/oDocument [
/oDocument/@type=‘Element’
and /oDocument/@parent = ‘C13ECC62C52B8000’]
/attributes/attribute
where $b/@key=‘C13ED8481ECA0000’ and xs:int($b/text()) != 123
return $b/@oDocKey
)

return $listKeys

In what a problem?

An initial comment: you don

I thought that too, but it works like this!

declare namespace xs='http://www.w3.org/2001/XMLSchema' 
let $listKeys := ( 
for $b in input()/oDocument [ 
/oDocument/@type='Element' 
and /oDocument/@parent = 'C13ECC62C52B8000'] 
/attributes/attribute 
where $b/@key='C13ED8481ECA0000' and xs:int($b/text()) != 123 
return $b/@oDocKey 
)
return $listKeys

And on sharing of function distinct-values(); and xs:int() gives out a mistake

Then I don

Full text XQuery:

 
declare namespace xs='http://www.w3.org/2001/XMLSchema' 
let $oDocs := ( 
for $b in input()/oDocument[
/oDocument/@type='Елемент' and 
/oDocument/@parent='C13ECC62C52B8000'
]/attributes/attribute  
where ($b/@key='C13ED8481ECA0000' and $b/text()!= '123')
return $b/@oDocKey) [position() >= 0 and position() <= 10] 

return ($oDocs)

OR

 
declare namespace xs='http://www.w3.org/2001/XMLSchema' 
let $oDocs := ( 
for $b in input()/oDocument[
/oDocument/@type='Елемент' and 
/oDocument/@parent='C13ECC62C52B8000'
]/attributes/attribute  
where ($b/@key='C13ED8481ECA0000' and xs:int($b/text())!= 123)
return $b/@oDocKey) [position() >= 0 and position() <= 10] 

return ($oDocs)

I think at this point I would contact Software AG support. It looks like a bug.
