Gilles Bayon commented on IBATISNET-165:
----------------------------------------
I don't think we need the attribute UseReturnValue whcih can be replace by
_statement.ResultClass != null ) &&
_sqlMap.TypeHandlerFactory.IsSimpleType (
_statement.ResultClass )
and so we have the code
else if (_statement is Procedure && (_statement.ResultClass != null) &&
_sqlMap.TypeHandlerFactory.IsSimpleType(_statement.ResultClass) )
{
IDataParameter returnValueParameter =
command.CreateParameter();
returnValueParameter.Direction =
ParameterDirection.ReturnValue;
command.Parameters.Add(returnValueParameter);
command.ExecuteNonQuery ( );
generatedKey = returnValueParameter.Value;
ITypeHandler typeHandler =
_sqlMap.TypeHandlerFactory.GetTypeHandler ( _statement.ResultClass );
generatedKey = typeHandler.GetDataBaseValue ( generatedKey,
_statement.ResultClass );
}
}
