The approach you outline, building a new date from the various date parts, looks something like this: select convert(varchar, datepart(year, @MyDate1)) + '/' -- year + right('0' + convert(varchar, datepart(month, @MyDate1)), 2) + '/' -- month + right('0' + convert(varchar, datepart(day, @MyDate1)), 2) + ' ' -- day + right('0' + convert(varchar, datepart(hour, @MyDate1)), 2) + ':00:00' -- hour plus 0 minutes and seconds A more streamlined way to drop the minutes and seconds would take advantage of the formatting options of the convert function ([ https://msdn.microsoft.com/en-us/library/ms187928.aspx][1]). I added the replace to conform to your desired format with the forward slash: select replace(left(convert(varchar, @MyDate1, 120), 14) + '00:00', '-', '/') If you prefer the output to be a datetime datatype, you can "replace" the replace function with another convert: select convert(datetime, (left(convert(varchar, @MyDate1, 120), 14) + '00:00')) [1]: https://msdn.microsoft.com/en-us/library/ms187928.aspx

I see someone beat me to it, but I was going to suggest: DECLARE @MyDate1 DATETIME='2014/04/28 15:15:15'; SELECT CAST((CAST(CAST(@MyDate1 AS DATE) AS VARCHAR) + ' ' + CAST(DATEPART(HOUR, @MyDate1) AS VARCHAR) + ':00:00') AS DATETIME);
