A
If only time value is provided in a DATETIME variable, the SQL Server will pad the date value with a zero, representing the base date, January 1, 1900. The tutorial exercise below gives you some good examples:
-- 'hh:mi:ss.mmm' format DECLARE @x DATETIME; SET @x = '22:55:07.233'; SELECT @x; ----------------------- 1900-01-01 22:55:07.233 -- 'hh:mi:ss.mmmAM/PM' format DECLARE @x DATETIME; SET @x = '10:55:07.233PM'; SELECT @x; ----------------------- 1900-01-01 22:55:07.233 -- 'hh:miAM/PM' format DECLARE @x DATETIME; SET @x = '10:55PM'; SELECT @x; ----------------------- 1900-01-01 22:55:00.000
