Summary: Effective boolean value of sequence results in an error
Initial Comment:
We use the MonetDB Nov 2008 SP1 server supplied by the Fedora 9 RPM's.
When we execute the following query, which we believe is valid, it results in
the following error:
Query:
element result {
if (distinct-values(exactly-one(doc("bookmarks.xml"))//*)) then 1 else 2
}
Mclient output:
xquery>\</media/disk/querylog
MAPI = mone...@localhost:51240
QUERY = element result {
ERROR = !fatal error: attribute 'item' with type '0x20' not found in environment
It executes without a problem, when we rewrite the query to the following:
Query:
element result {
if (not(empty(distinct-values(exactly-one(doc("bookmarks.xml"))//*)))) then 1
else 2
}
Mclient output:
xquery>\</media/disk/querylog.workaround
<result>1</result>
