Enumerated type a character limitation

BIZ TMS Aurelius

Hello!

I have a legacy DB and I want the application to use Aurelius on it, but I have a problem.

There is a field in the DB table that is char(1) and can have values "0" (zero), "+","-". The classes are already defined in the old version of the App (before Aurelius), so I wouldn't like to change the classes if possible.

I try to use this mapping

  [Enumeration(TEnumMappingType.emChar, '0,+,-')]
  TDocStockInfluence = (dsiNoInfluence, dsiIncrease, dsiDecrease);

myclass = class
...
    [Column('STOCK_INFLUENCE')]
    FStockInfluence: TDocStockInfluence;
...

But in run-time i get the error Enum mapped value "0" is invalid for type "emChar", I suppose the problem will be also for "+" and "-" character..?

Is possible to alter the enum to accept and character? I would suggest to allow any character to be used.

Why is zero not allowed? It's treated like a character, not a number in the application. Since there are around 200 databases, is very important to achive the goal without DB or class changes for compatibility with the old application.

You can simply use emString instead of emChar and everything will work the same.

Ops, I haven't even seen the option. Sorry, my mistake.
