SQL Server 2008 :: Compare Data Between Identical Table Structure?

I have two identical table structure with at least 60 or more columns!!

Table A
ID numeric(18, 0) Primary Key,
RefID numeric(18, 0),
CoNum Varchar(15),
PrevCode Varchar(15),
DispCode VArchar(15),
EffDate Date,
Sal numeric(18, 0),
SDeposit numeric(18, 0) Etc....

I need to compare Data between two table and provide result like this!

RefId ID, CoNum, PrevCode, DispCode, EffDate, Sal, SDeposit
1, ,No Match, ,20,5200,0

So condition like. If table A Column Data does not Equal Table B Column data then

If datatype is Date then display Difference of Days.

if Datatype is Numeric then display Difference between value.( it display 0 if doesn't have difference)

if Datatype is Varchar then display No Match word.
