I am trying to declare a datetime variable with the value 1001-01-01 00:00:00.000

I have tried the following approaches with no luck

declare @d1 datetime = '1001-01-01';
declare @d2 datetime = 10010101;
declare @d3 datetime = '1001-01-01 00:00:00';
declare @d4 datetime = cast ('1001-01-01' as datetime)

I get the following errors

Msg 242, Level 16, State 3, Line 1
The conversion of a varchar data type to a datetime data type resulted in an out-of-range value.
Msg 8115, Level 16, State 2, Line 2

Is it possible to declare a datetime variable which can hold the value 1001-01-01 00:00:00.000?

Try DATETIME2, using:

DECLARE @d4 DATETIME2 = '1001-01-01'

The minimum valid date for DATETIME2 is 0001-01-01

  • datetime is not a structure, it's a data type. I think that you have it confused with the DateTime structure in the .NET framework. You don't need to cast a date literal to assign it to a datetime2 variable. Also, was it you who downvoted all other answers?
  • @Guffa Ah yeah, thanks for the clarity :). Nah it wasn't me, I'll upvote you at the daily reset to thank you for the edit clarifications :).
  • There is nothing wrong with your answer and it doesn't warrant a downvote at all. Seems like a drive-by serial downvoter came by
