if you are using sql server , then you can create a stored procedure like this:

IF EXISTS (SELECT Name From table1 WHERE Name =@Name and address=@address and city=@city and pincode=@pincode)

BEGIN

SET @ReturnVal ='Already Exists!'

--Return @ReturnVal

END

ELSE

BEGIN

--here execute insert query
End
end try
