You need to use a calendar table or a tally table as the main table for your query. You need to have a row for the date when there are no details. Do a quick search on this site for calendar tables.
If you need specific coding help please take a few minutes and read the article at the first link in my signature for best practices when posting questions.

Are you using SSRS or Crystal Reports? I had this issue once with Crystal. First I used data grouping to summarize records for each day of the week, but if there were no records for a particular day, that day was missing - but the client wanted to see all 7 days with zero total if the day had no records.
What I ended up doing was a separate formula for each day of the week that counts records for that day, then put all seven formulas in one report section. It was more work, but it did show all seven days and zeros for days with no records.
I'm not very familiar with SSRS, so if that's what you're using I hope this is helpful.

you have to select form a CalendarTable, which would contain all possible dates, and left join it to your data that has the rest of the data.
you can generate a Calendar on the fly, or create a permanent one , because it's very useful for reports like this.
one example:
SET DATEFORMAT MDY
CREATE TABLE #myBalances (
[TranDate] DATETIME,
[TransactionAmount] money,
[Balance] money)
INSERT INTO #myBalances VALUES ('12/1/2008',100,100)
INSERT INTO #myBalances VALUES ('12/3/2008',-60,40)
INSERT INTO #myBalances VALUES ('12/4/2008',10,50)
DECLARE @StartDate DATETIME, @EndDate DATETIME
SET @StartDate = '11/15/2008'
SET @EndDate = '12/6/2008'
SELECT TallyCalendar.TheDate AS TranDate, ISNULL(b.TransactionAmount, 0) AS TransactionAmount, ISNULL(x.Balance ,0)
FROM (
SELECT dateadd( dd,-3650 + RW ,DATEADD(dd, DATEDIFF(dd,0,getdate()), 0)) As TheDate
FROM (
SELECT TOP 7300
row_number() OVER (ORDER BY sc1.id) AS RW
FROM Master.dbo.SysColumns sc1
CROSS JOIN Master.dbo.SysColumns sc2
) X
)TallyCalendar
LEFT JOIN #myBalances b ON b.TranDate = DATEADD(DD, 0, TallyCalendar.TheDate)
LEFT JOIN #myBalances x ON x.TranDate = (SELECT MAX(TranDate) AS TranDate FROM #myBalances WHERE TranDate <= TallyCalendar.TheDate)
WHERE TallyCalendar.TheDate BETWEEN @StartDate AND @EndDate
DROP TABLE #myBalances

That won't work for missing days unless you have a reference (like a Calendar table or Tally Table driven result set) to be able to join to to establish what the missing days actually are.
