How to use Union method or left outer join?
I cannot join #Temp with scr_SecuristLog. How can I do it?
CREATE TABLE #Temp (VisitingCount int, [Time] int )
DECLARE @DateNow DATETIME,@i int,@Time int
set @DateNow='00:00'
set @i=1;
while(@i<48)
begin
set @DateNow = DATEADD(minute, 30, @DateNow)
set @Time = (datepart(hour,@DateNow)*60+datepart(minute,@DateNow))/30
insert into #Temp(VisitingCount,[Time]) values(0,@Time )
set @i=@i+1
end
select VisitingCount, [Time]
from #Temp as t
left outer join (
select count(page) as VisitingCount,
(datepart(hour,Date)*60+datepart(minute,Date))/30 as [Time]
from scr_SecuristLog
where Date between '2009-05-04' and '2009-05-05'
) as s
on t.VisitingCount = s.VisitingCount
and t.Time = s.Time
These codes give an error:
Msg 8120, Level 16, State 1, Line 1 Column "scr_SecuristLog.Date" is not valid in the select list because it is not contained in either an aggregate function or a GROUP BY clause.
Msg 8120, Level 16, State 1, Line 1 Column "scr_SecuristLog.Date" is not valid in the select list because it is not contained in either an aggregate function or a GROUP BY clause.
Msg 209, Level 16, State 1, Line 1 Ambiguous column name "VisitingCount".
Msg 209, Level 16, State 1, Line 1 Ambiguous column name "Time".

As you didn't mention the specific error, I'm guessing that your error comes from the fact that you are not prefixing your select values.
select t.VisitingCount, t.[Time]
Edit
Your second error should be resolved with this group.
select count(page) as VisitingCount,
(datepart(hour,Date)*60+datepart(minute,Date))/30 as [Time]
from scr_SecuristLog
where Date between '2009-05-04' and '2009-05-05'
GROUP BY (datepart(hour,Date)*60+datepart(minute,Date))/30

Ok try this
CREATE TABLE #Temp (VisitingCount int, [Time] int )
DECLARE @DateNow DATETIME,@i int,@Time int
set @DateNow='00:00'
set @i=1;
while(@i<48)
begin
set @DateNow = DATEADD(minute, 30, @DateNow)
set @Time = (datepart(hour,@DateNow)*60+datepart(minute,@DateNow))/30
insert into #Temp(VisitingCount,[Time]) values(0,@Time )
set @i=@i+1
end
select t.VisitingCount, t.[Time]
from #Temp as t
left outer join (
select count(page) as VisitingCount,
(datepart(hour,Date)*60+datepart(minute,Date))/30 as [Time]
from scr_SecuristLog
where Date between '2009-05-04' and '2009-05-05'
GROUP BY scr_SecuristLog.Date
) as s
on t.VisitingCount = s.VisitingCount
and t.Time = s.Time

Your inner choices (which you are joining) are not being aggregated properly. You have a counter and a column. This means you need to group the SQL column to understand correctly.
select t.VisitingCount, t.[Time]
from #Temp as t
left outer join (
select count(page) as VisitingCount,
(datepart(hour,Date)*60+datepart(minute,Date))/30 as [Time]
from scr_SecuristLog
where Date between '2009-05-04' and '2009-05-05'
GROUP BY [Date]
) as s
on t.VisitingCount = s.VisitingCount
and t.Time = s.Time
Actually you may need to group the calculated column, in which case your group should be:
GROUP BY (datepart(hour,Date)*60+datepart(minute,Date))/30
