SMALLDATETIMEFROMPARTS ( year, month, day, hour, minute ) Returns a datetimeoffset value for the specified date and time, with the specified offsets and precision. Returns a datetime value for the specified date and time.ĭATETIMEOFFSETFROMPARTS ( year, month, day, hour, minute, seconds, fractions, hour_offset, minute_offset, precision) Returns a datetime2 value for the specified date and time, with the specified precision.ĭATETIMEFROMPARTS ( year, month, day, hour, minute, seconds, milliseconds)
Returns a date value for the specified year, month, and day.ĭATETIME2FROMPARTS ( year, month, day, hour, minute, seconds, fractions, precision) Returns an integer representing the year part of a specified date.įunctions that return date and time values from their parts Function Returns an integer representing the month part of a specified date. Returns an integer representing the day part of the specified date. Returns an input date truncated to a specified datepart. Returns an integer representing the specified datepart of the specified date. Returns a character string representing the specified datepart of the specified date. The return type depends on the argument supplied for date. Returns a value corresponding to the start of each date-time bucket from the timestamp defined by the origin parameter, or the default origin value of 00:00:00.000 if the origin parameter isn't specified. The function returns the date and time values as UTC time (Coordinated Universal Time).įunctions that return date and time parts FunctionĭATE_BUCKET ( datepart, number, date, origin ) Returns a datetime value containing the date and time of the computer on which the instance of SQL Server runs. The returned value doesn't include the time zone offset. Lower-precision system date and time functions Function The function returns the date and time values as UTC time (Coordinated Universal Time). Returns a datetime2(7) value containing the date and time of the computer on which the instance of SQL Server is running. The returned value includes the time zone offset. Returns a datetimeoffset(7) value containing the date and time of the computer on which the instance of SQL Server runs. Returns a datetime2(7) value containing the date and time of the computer on which the instance of SQL Server runs.
SETDATE SQL WINDOWS
Use the GetSystemTimeAdjustment() Windows API to determine the accuracy. This API has a precision fixed at 100 nanoseconds. The accuracy depends on the computer hardware and version of Windows on which the instance of SQL Server running. Since SQL Server 2008 (10.0.x), the Database Engine derives the date and time values through use of the GetSystemTimeAsFileTime() Windows API. Higher-precision system date and time functions Transact-SQL derives all system date and time values from the operating system of the computer on which the instance of SQL Server runs. Functions that return system date and time values See Deterministic and Nondeterministic Functions for more information about determinism. The following tables list the Transact-SQL date and time functions. timestamp is a deprecated synonym for rowversion. The Transact-SQL rowversion data type is not a date or time data type. The Transact-SQL date and time data types are listed in the following table: Data typeĠ0:00:00.0000000 through 23:59:59.9999999 Functions that validate date and time values.Functions that set or return session format functions.Functions that modify date and time values.Functions that return date and time difference values.Functions that return date and time values from their parts.
