Example 2: DATETIMEFROMPARTS – with valid date and time part integer variables

DECLARE @year INT = 2013, @month INT = 6, @day INT = 23,
        @hour INT = 1, @minute INT = 20, @seconds INT = 14, 
        @milliseconds INT = 878
SELECT DATETIMEFROMPARTS( @year, @month, @day, 
        @hour , @minute, @seconds, @milliseconds) AS 'DATETIME'

Result:

DATETIME

Example 3: DATETIMEFROMPARTS – with Invalid part

DECLARE @year INT = 2013, @invalidmonth INT = 15, @day INT = 23,
        @hour INT = 1, @minute INT = 20, @seconds INT = 14, 
        @milliseconds INT = 878
SELECT DATETIMEFROMPARTS( @year, @invalidmonth, @day, 
        @hour , @minute, @seconds, @milliseconds) AS 'DATETIME'

Result:
Msg 289, Level 16, State 3, Line 3
Cannot construct data type datetime, some of the arguments have values which are not valid.

Example 4: DATETIMEFROMPARTS – with one of the part as NULL

DECLARE @year INT = 2013, @month INT = 6, @day INT = 23,
        @hour INT = 1, @minute INT = 20, @seconds INT = NULL, 
        @milliseconds INT = 878
SELECT DATETIMEFROMPARTS( @year, @month, @day, 
        @hour , @minute, @seconds, @milliseconds) AS 'DATETIME'
