Frequent Visitor

DateTime comparisons



I have a table that shows data on when visits are created for different buildings and when the visitor has checked-in.

How could I check if a visit has been created after 4PM the previous day the visitor has come in and bring back the amount of such visits?


Thank you in advance!

SQL BI has a good article on how to add/remove date time in measures here:


You could use variables to store all the things you're comparing. My roundabout guesstimate to get the 4pm the day before for comparison would be to subtract a day from the given date, convert it to date only, then convert it back to date time and add the hours up to 4pm to it. Then you can compare it to the date field in your data and return a true/false if it's greater than or less than the 4pm prior day.
