sql-server - Date format with zeros

Question

With this:

, CAST(DATEPART(Yy,DATEADD(Month,1,GETDATE())) as varchar(4)) + '-' + 
CAST(DATEPART(Mm,DATEADD(Month,1,GETDATE())) as varchar(2)) + '-' +
CAST(DATEPART(Dd,DATEADD(Month,1,GETDATE())) AS varchar(2)) AS expiration_date

I get this: 2013-9-2

What I need is 2013-09-02

Need to have the 0 before single digit dates. What needs to be changed?

Thank you

如果这是 SQL Server，请使用CONVERT：

 SELECT CONVERT(varchar(10), DATEADD(Month,1,GETDATE()), 120)

如果您需要该日期的前一天，请DATEADD再次使用：

SELECT CONVERT(varchar(10), DATEADD(Day, -1, DATEADD(Month,1,GETDATE())), 120)
