I just found and enter a ticket about this one.
I've been a little further.
Select Count(1) failes with "Unsupported FDO type in expression"
It was working ok in release 3.2
I think i have found were the problem is.
ProcessAggregateFunction has been overridden in release 3.3 ( to handle ALL
and distinct i guess)
extract of ProcessAggregateFunction function
if (dataValue->GetDataType() == FdoDataType_String)
// Omit ALL if specified as this keyword is not supported in
"Unsupported FDO type in expression"));
As 1 is not a string -> boom
I have tried with
Select Count('1') and it works fine
