Title Body

I need to make a temporary table that holds of range of dates, as well as a couple of columns that hold placeholder values (0) for future use. The dates I need are the first day of each month between $startDate and $endDate where these variables can be several years apart. My original sql statement looked like this: select dbo.FirstOfMonth(InsertDate) as Month, 0 as Trials, 0 as Sales into #dates from customer group by dbo.FirstOfMonth(InsertDate) "FirstOfMonth" is a user-defined function I made that pretty much does what it says, returning the first day of the month for the provided date with the time at exactly midnight. This produced almost exactly what I needed until I discovered there were occasionally gaps in my dates where I had a few months were there were no records insert dates. Since my result must still have the missing months I need a different approach. I have added the following declarations to the stored procedure anticipating their need for the range of the dates I need ... declare $startDate set $startDate = select min(InsertDate) from customer declare $endDate set $endDate = select max(InsertDate) from customer ... but I have no idea what to do from here. I know this question is similar to this question but, quite frankly, that answer is over my head (I don't often work with SQL and when I do it tends to be on older versions of SQL Server) and there are a few minor differences that are throwing me off.
