SDU Tools: Dates in a Period in SQL Server T-SQL

It’s common to need to get a table of all dates between two dates, and in our free SDU Tools for developers and DBAs, we have a function DatesBetween that I’ve previously talked about. But sometimes it’s not a start and end date that you have, it’s a start date and a number of intervals. For example, I might want all the dates for the next three months, or three weeks, or two years. To make that easy, we’ve added a function called DatesInPeriod.

It’s a table-valued function that takes three parameters:

@StartDate is the first date to return @NumberOfIntervals is (no surprise) the number of intervals to include @IntervalCode is a string that can include YEAR, QUARTER, MONTH, WEEK or DAY.

For each date in the number of intervals, it returns a key (an incrementing number for the position of the date within that period), and the date.

You can use our tools as a set or as a great example of how to write functions like these.
