The DATE function creates a date in the standard date format from a text string representing the day, month and year. You can also optionally include the time with this function.

Syntax

DATE(year, month, day [,hour, minute, second])

Return: Date in the format defined by Date Format

Example

DATE (1988, 3, 7, 3, 22, 45) = '03/07/1988 03:22:45'

DATEADD

The DATEADD function adds a number to an existing date, date/time, or time variable.

Syntax

DATEADD('dString', number[,DAY or MONTH or YEAR or HOUR or MINUTE])

DATEADD('time field', number[,DAY or MONTH or YEAR or HOUR or MINUTE])

DATEADD('date field', number[,DAY or MONTH or YEAR or HOUR or MINUTE])

DATEADD('time and date field', number[,DAY or MONTH or YEAR or HOUR or MINUTE])

where number represents a day, month, year, hour, or minute.

If the first argument is of type time, only hour or minute are allowed as the last argument.

Return: Date in the format defined by Date Format

Examples

DATEADD('11/24/1963', 6) = '11/30/1963 12:00 AM'
DATEADD('01/24/1964 12:12 PM', 6, 'MONTH') = '07/24/1964 12;12 PM'
DATEADD('02:12 PM', 40) = '02:52 PM'

DATECOMP

The DATECOMP function compares two given dates, datetimes, or times and returns:

For two given dates or datetimes, the difference in days
For two given times, the difference in minutes

Syntax

DATECOMP(dString, dString)

See Date Format for more detail on the parameters used in this function.

If the first argument is of type time, only hour or minute are allowed as the last argument.

Return: Number

Example

DATECOMP('04/15/2010', '04/05/2010') = 10
DATECOMP('04/05/2010', '04/15/2010') = -10
DATECOMP(TODAY(), '04/05/2010') = 10 when TODAY is 04/15/2010 
DATECOMP(TODAY(), Closed_Date) = 10 when TODAY is 04/15/2010 and Closed_Date is 04/05/2010
DATECOMP('04/15/2010 10:15 am', '04/05/2010 1:15 am') = 10
DATECOMP('10:23 PM', '2:52 AM') = 1171.0
DATECOMP('10:23 AM', '2:52 PM') = -269.0

DATEPART

The DATEPART function returns a date/time value that is normalized to the start of the day, to match other date/time values on the same day.

Note:
To get a string that contains the date only, use this:

TEXT(MONTH(date_modified))+'/'+TEXT(DAY(date_modified))+'/'+TEXT(YEAR(date_modified)) </syntaxhighlight>

Syntax: <syntaxhighlight lang="java" enclose="div">

DATEPART('dString')) </syntaxhighlight>

Return: A date in the format defined by Date Format

Examples: <syntaxhighlight lang="java" enclose="div">

DATEPART('04/22/2009 03:15 am') = '04/22/2009 12:00:00 AM'

DATEPART(DATE ('2009', '04', '22', '03', '15', '00')) = '04/22/2009 12:00:00 AM' </syntaxhighlight>

DATESUB

The DATESUB function does one of two things:

Subtracts a number from a date, datetime, or time variable, and returns a date
Subtracts a date, datetime, or time variable from another date, datetime, or time variable, and returns a number

Syntax

 DATESUB('dString', 'dString' or number [,'DAY' or 'MONTH' or 'YEAR' or 'HOUR' or 'MINUTE'])

Return: A date in the format defined by Date Format; An integer representing the number of days

Example

DATESUB('12/06/2010', 2, 'MONTH') = '10/06/2010'
DATESUB('12/06/2010', 2, 'YEAR') = '12/06/2008'
DATESUB('12/06/2010', 2, 'DAY') = '12/04/2010'
