Hi,
we have in fcl-db TField.AsBCD: TBCD; but we do not have TParam.AsBCD, nor
TParam.AsFMTBCD
Delphi defines:
TParam.AsBCD: Currency ...

TParam.AsFMTBCD: TBCD ...
http://docwiki.embarcadero.com/VCL/XE/en/DB.TParam.AsFMTBCD
But for me sounds more logical and consistent, that TParam.AsBCD will be like
TField.AsBCD so result type will be TBCD
(TParam.AsBCD: Currency is more like TParam.AsCurrency: Currency)
So what way to go ?
1. TParam.AsBCD: TBCD
2. TParam.AsFMTBCD: TBCD
Well, the Delphi compatible way is usually preferred.
It makes no sense to have both .asBCD and asFMTBCD to have the same result type.
The same can of course be said about .asBCD and .AsCurrency; But since
Delphi compatibility is a goal, I think we should follow them.
Borland could perfectly have sufficed with 2 properties (.AsCurrency, AsBCD).
For some reason they introduced 3.
