  Hi,
  Anyone can help on sql how to display milliseconds to a date format?
  DateCreated
  -----------------
  1539453603609
  1539453605407
  1540436130996
  1542004320409
  ...
  ...

  I need an output format
  YYYYMMDD_HHMM

  Thank you in advanced;

  You will have to divide the values in hours and milliseconds.
  😎
  
DECLARE @BMS BIGINT = 1542004320409;
DECLARE @bh INT  = @BMS / 3600000;
DECLARE @ims INT  = @BMS % 3600000;
SELECT DATEADD(MILLISECOND,@IMS,DATEADD(HOUR,@BH,CONVERT(DATETIME2(3),'19700101',112)));


  Note that I put 1530-01-01 as the initial date, no idea what that should be.
  Edit: not enough coffee that morning, corrected the calculation.

  Hi Eirikur,

  Appreciate your great help, but how can I applied this on may table "system_log" column "DateCreated"?

  Thank you very much

  The format looks like a unix timestamp. Although the unix epoch is in "seconds" after Jan-1 -1970. Are you looking to convert from seconds to datetime format?

  Actually, it's milliseconds after 1 Jan 1970 and the following will easily do the initial conversion thanks to the inherent temporal math capabilities of the DATETIME datatype.

  SELECT CONVERT(DATETIME,1539453603609/86400000.0)+'1970';

  The number 86400000.0 is the number of milliseconds in a day. (1000*60*60*24)

  If you're one of those folks that don't believe in the simplicity of direct temporal math, you could also do this based on the SQL Server epoch of 1 Jan 1900.

  SELECT DATEADD(yy,70,1539453603609/86400000.0) --70 is the number of years since 1 Jan 1900

  Don't know what time of precision is required but the datetime conversion adds one millisecond.
  😎
  
DECLARE @BMS BIGINT = 1539453603609;
DECLARE @bh INT  = @BMS / 3600000;
DECLARE @ims INT = @BMS % 3600000;

  You can do that either via a view on top of the table or as a calculated column.

  Hopefully, this is just for presentation purposes and you won't actually store the information in any permanent table in the format you requested.

  This will do it if the column name for the original value actually is "DateCreated".
  
 SELECT DateCreated = REPLACE(REPLACE(REPLACE(
                        CONVERT(CHAR(16),DATEADD(yy,70,DateCreated/86400000.0),121) COLLATE Latin1_General_BIN
                      ,'-',''),':',''),' ','_')
   FROM dbo.YourTable
;

  The COLLATE clause can significantly increase the performance of the already fast nested REPLACEs, depending on what your current default collation is.
