Answer 1

这是我计算总金额的方法：

DECLARE @Current_LeaseEndDate DATE = '01/31/2021'  --3 Years
DECLARE @PercentIncrease  FLOAT = .05
DECLARE @Principal FLOAT = 100

SELECT 
YEAR(DATEADD(day, 1, CAST(@Current_LeaseEndDate AS VARCHAR(10))) + 1),
CASE WHEN YEAR(DATEADD(day, 1, CAST(@Current_LeaseEndDate AS VARCHAR(10))) + 1) >= YEAR(GETDATE())
        THEN @Principal * POWER((1 + @PercentIncrease), YEAR(DATEADD(day, 1, CAST(@Current_LeaseEndDate AS VARCHAR(10))) + 1) - YEAR(GETDATE()))
        END AS MEH
