date_diff()

Returns the amount of time between two dates. This function is only valid in a foreach statement.

Syntax

date_diff(datepart,startdate,enddate)

datepart specifies how you want to measure the time interval:
  • year
  • month
  • quarter
  • day
  • week
  • hour
  • minute
  • second

startdate specifies the start date.

enddate specifies the end date.

Usage

Returns the time difference between two dates in years, months, or days. For example,

date_diff("year", toDate("31-12-2015", "dd-MM-yyyy"), toDate("1-1-2016", "dd-MM-yyyy")) returns 1.

If startdate is after enddate the difference is returned as a negative number.

You must use date_diff() in a foreach() statement. You cannot use this function in group by, order by, or filter statements.

Example - How Many Weeks Did Each Opportunity Take to Close?

Use date_diff() with datepart = week to calculate how long, in weeks, it took to close each opportunity.

Example - How Long Ago Was an Opportunity Closed?

Use date_diff() with datepart = month to calculate how many months have passed since each opportunity closed. Use now() as the end date.
