How to compare a field value that contains date only to today's date?

maurkb — Thu, 22 Dec 2016 23:05:16 GMT

I have looked at all of the date comparison questions/answers but cannot find an answer to this question. I have a field (StandInDay) which contains only the date, no time (StandInDay=2016-12-01). In my dashboard, I want a panel that displays the number of transactions in which this StandInDay value matches today's date (among other criteria). So basically, the number of these transactions in which the StandInDay is equal to today, but I cannot seem to get it to work. I have tried converting to epoch and comparing to now() but that doesn't work. Any suggestions?

Today's date is not a single epoch time value, but a range of values, so comparing to now() - which is the precise start time of the search - isn't going to work.

The easiest way to do this is to convert now() to a text field in the same format as StandInDay, like this

yoursearchhere
| eval today=strftime(now(),"%Y-%m-%d")
| where StandInDay=today

This should do the trick.
