sql - Get default value for date

Question

According to the doc the default value of a date in SQL Server is

1900-01-01 00:00:00

Can I call the default value in any way? For instance like this

select isnull(date_column, default(date_column))
from my_table

Answer 1

也许：

SELECT DefaultDate = CAST(0 AS DATETIME)

如果你需要一个DATE，你也可以投射它：

SELECT DefaultDate = CAST(CAST(0 AS DATETIME) AS DATE)
