Hello,
I'm having trouble when using SPIN function arguments within a FILTER
statement. E.g. using the spinsquare model I initially added a simple
twoDimArea function that seems to work correctly:
SELECT ?result
WHERE {
LET (?result := (?arg1 * ?arg2)) .
}
When I call it with something like:
SELECT ?value
WHERE {
?rec spinsquare:width ?width .
?rec spinsquare:height ?height .
LET (?value := SpinLib:twoDimArea(?width, ?height))
}
the correct values are returned based on what's in the model. However,
if I change the function query to filter out everything except squares:
SELECT ?result
WHERE {
FILTER (?arg1 = ?arg2) .
LET (?result := (?arg1 * ?arg2)) .
}
The filtering doesn't happen, I still get all the results. I've tried
other variations of FILTER statements that uses only one argument and
none of them seem to do any filtering. Should FILTER statements within
SPIN Functions work?
Thanks,
Jeff
