SQL Syntax

I'm trying to understand someone else's syntax: -

These are the parameters: -
      DECLARE @TodayStart AS DATETIME, @TodayEnd AS DATETIME
      SET @TodayStart = DATEADD(dd, DATEDIFF(dd,0,getdate()), 0)
      SET @TodayEnd = DATEADD(dd, 1, @TodayStart)

This is the 'where' part of the query: -
      WHERE [ReceiptDate] >= '''+@TodayStart+'''
      AND [ReceiptDate] < '''+@TodayEnd+'''

Can anyone tell me what date range will be returned by this query?

lol ... i guess this are the same 2 lines
SET @TodayStart = DATEADD(dd, DATEDIFF(dd,0,getdate()), 0)

SET @TodayStart = getdate()


daterange is from today until tomorrow

So, even though it is convoluted, the results will be transactions from 'Today'?

You can also replace   SET @TodayStart = DATEADD(dd, DATEDIFF(dd,0,getdate()), 0)
with   SET @TodayStart = convert(varchar, getdate(), 111), which is just trimming the time part from datetime value.
