Hi Jackie,

Do you call the function like below?

Thanks,
Romy.

FdoPtr<FdoISelectAggregates> select = (FdoISelectAggregates*)m_connection->CreateCommand (FdoCommandType_SelectAggregates);
FdoPtr<FdoIdentifierCollection> identifiers = select->GetPropertyNames();
FdoPtr<FdoIdentifier> identifier;

identifier = FdoComputedIdentifier::Create(L"SE_NAME", FdoPtr<FdoExpression>(FdoExpression::Parse(L"SpatialExtents(geometry)")));
identifiers->Add(identifier);

Hi All,

Does the SQLite FDO provider support the SpatialExtent() aggregate function?

The capabilities say it does, but when I try to execute an
FdoISelectAggregate command containing a SpatialExtent() computed property,
it throws back an exception:

no such function: SpatialExtents
