Constraint Prob -Please help

Question

Can we check default value while adding constraint in oracle9i like below example is in SQL and doing that.
ALTER TABLE dbo.AdjustmentReasons WITH NOCHECK ADD
CONSTRAINT DF_AdjustmentReasons_IAdjustmentType
DEFAULT (0) FOR IAdjustmentType,
CONSTRAINT DF_AdjustmentReasons_FLogicalAdjustment
DEFAULT (0) FOR FLogicalAdjustment,
CONSTRAINT DF_AdjustmentReasons_fGenerateAdvice
DEFAULT (0) FOR fGenerateAdvice,
CONSTRAINT DF_AdjustmentReasons_IForceBalType
DEFAULT (0) FOR IForceBalType,
CONSTRAINT IForceBalType_chk CHECK (IForceBalType >= 0
and IForceBalType <= 2),
CONSTRAINT DF_AdjustmentReasons_ILogicalInsertShortCutKey
DEFAULT (255) FOR ILogicalInsertShortCutKey,
CONSTRAINT DF_AdjustmentReasons_FLogicalInsertAutoPosition
DEFAULT (0) FOR FLogicalInsertAutoPosition
Can we do like
alter table <tablename> add constraint CON check (<fieldname> default 0))
