A way to extract from a DateTime value data without seconds

Question

I have an sql DateTime (ms sql server) and want to extract the same date without the seconds: e.g. 2011-11-22 12:14:58.000 to become: 2011-11

Answer 1

To Round Off it:

DECLARE @TheDate DATETIME;
SET @TheDate = '2019-1-2 12:14:58.400';

SELECT CAST(@TheDate AS SMALLDATETIME);

To just Truncate:

DECLARE @TruncTheDate DATETIME;
SET @TruncTheDate = '2019-1-2 12:14:58.400';

SELECT DATEADD(mi, DATEDIFF(mi, 0, @TruncTheDate), 0);
