Is there a way to query for the days in a month? For example, querying for the days in January of this year? Listing the days between two dates would be useful as well. I'm sure I saw a query like this somewhere, but I can't track it down. Just to be clear, there were no tables involved. Just a SELECT statement that returned all the days in a given month. Basically, I have a table of "events" and I'd like to generate a histogram of how many events occur on the days of a particular month. What I do now is create a temporary table, fill it with the appropriate days, and then do a cross join and summation to generate what I need. This works, but seems messy to me.
