Using built-in CRM functions when writing SQL Reports

If you've ever worked with CRM's Advanced Find you know what an amazing number of built-in date query parameters there are.  It turns out, that those query parameters have corresponding user-defined SQL functions that you can use in your own queries for operations such as custom reports.

Here is a list of some of the more common date functions:

fn_BeginOfDay
fn_BeginOfHour
fn_BeginOfLastMonth
fn_BeginOfLastSevenDay
fn_BeginOfLastWeek
fn_BeginOfLastXDay
fn_BeginOfLastXHour
fn_BeginOfLastXWeek
fn_BeginOfLastYear
fn_BeginOfMonth
fn_BeginOfNextMonth
fn_BeginOfNextWeek
fn_BeginOfNextYear
fn_BeginOfThisMonth
fn_BeginOfThisWeek
fn_BeginOfThisYear
fn_BeginOfToday
fn_BeginOfTomorrow
fn_BeginOfWeek
fn_BeginOfYear
fn_BeginOfYesterday
fn_EndOfLastMonth
fn_EndOfLastWeek
fn_EndOfLastYear
fn_EndOfNextMonth
fn_EndOfNextSevenDay
fn_EndOfNextWeek
fn_EndOfNextXDay
fn_EndOfNextXHour
fn_EndOfNextXWeek
fn_EndOfNextYear
fn_EndOfThisMonth
fn_EndOfThisWeek
fn_EndOfThisYear
fn_EndOfToday
fn_EndOfTomorrow
fn_EndOfYesterday
fn_FirstDayOfMonth
fn_LastXMonth
fn_LastXYear
fn_LocalTimeToUTC
fn_NextXMonth
fn_NextXYear
fn_NTDayOfWeek

If you would like to see these functions in action, copy the following script into SQL Management Studio and run it ( after connecting to the CRM database ):
