Hi,
I have table
CREATE TABLE [dbo].[Asset](
    [item] [nvarchar](50) NULL,
    [bought_date] [date] NULL,
    [price] [numeric](18, 2) NULL,
    [AssetLife] [numeric](18, 0) NULL,
    [end_date] [date] NULL,
    [AssetCurrentDate] [date] NULL,
    [AssetDedPercent] [numeric](18, 2) NULL
) ON [PRIMARY]
GO
and the data is 
INSERT INTO [Accounts].[dbo].[Asset]
           ([item]
           ,[bought_date]
           ,[price]
           ,[AssetLife]
           ,[end_date]
           ,[AssetCurrentDate]
           ,[AssetDedPercent])
     VALUES
           ('x',
           '2019-01-01'
           ,'4000000.00'
           ,'10'
           ,null
           ,null
           ,20)
GO
Looking for below result.
