Subject: [GENERAL] Days in month query
Greetings,
This is more of an SQL question, but since each database server seems
to use it's own syntax for handling dates...
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.
Mark
