Create a Dynamic Pivot Table 1

Hi

I have a small database on MS SQL 2008 R2 for holding call log data from our phone system. Recently I setup a small call centre and they need to see how many calls have come in during each hour of the day across a whole calendar month.

I immediately thought that a Pivot table would do the trick, but I'm having a lot of trouble trying to create one. I started out with the following query to extract the relavent data:

SQL:
DECLARE @DATEFROM DATETIME
DECLARE @DATETO DATETIME
DECLARE @LIST TABLE (Value VARCHAR(8))

Set @DATEFROM	= '2014-01-01T00:00:00'
Set @DATETO		= '2014-01-31T23:59:59'
INSERT INTO @LIST VALUES ('17351')
INSERT INTO @LIST VALUES ('17141')
INSERT INTO @LIST VALUES ('17401')
INSERT INTO @LIST VALUES ('17186')
INSERT INTO @LIST VALUES ('17264')
INSERT INTO @LIST VALUES ('17124')

Select		Convert(VarChar, LogDate, 103) As "Date",
			Convert(VarChar, DatePart(Hour, LogDate)) + ':00' As "Hour",
			COUNT(TermID) As "No. Of Calls"			
From		Calls
WHERE		Calls.TermID IN (SELECT Value FROM @LIST)
AND			Calls.LogDate BETWEEN @DATEFROM AND @DATETO
	
GROUP BY	Convert(VarChar, LogDate, 103), DatePart(Hour, LogDate)
ORDER BY	Convert(VarChar, LogDate, 103), DatePart(Hour, LogDate)

This produces the following result:

Code:
Date                           :Hour                             No. Of Calls

But try as I might, I cannot turn this query into a Pivot table. Has anyone done something similar or have any of you got any ideas that might help?
 
can you give a data example of what you have and what you want it to look like

This is a sample of the raw date from the Calls table:

(20 row(s) affected)

The OrigID and TermID are type VarChar(8) the LogDate is DateTime

I'd like to to come out something like this:

Code:
             08:00   09:00   10:00   11:00   12:00   13:00   14:00   15:00   16:00

14/01/2014       9       7       4       4       6       4       3       1       0


I'd like to produce this for each month (I've only got two days worth of data at the moment)
 
ah, Makes more since. Send your results from your query above to a Temp table. Then Pivot that.

insert into mypivot values ('01/13/2014','8:00',2)
insert into mypivot values ('01/13/2014','9:00',4)
insert into mypivot values ('01/13/2014','10:00',8)
insert into mypivot values ('01/13/2014','11:00',5)
insert into mypivot values ('01/13/2014','12:00',7)
insert into mypivot values ('01/13/2014','13:00',5)
insert into mypivot values ('01/13/2014','14:00',4)
insert into mypivot values ('01/13/2014','15:00',3)
insert into mypivot values ('01/13/2014','16:00',2)
insert into mypivot values ('01/14/2014','9:00',9)
insert into mypivot values ('01/14/2014','10:00',7)
insert into mypivot values ('01/14/2014','11:00',4)
insert into mypivot values ('01/14/2014','12:00',4)
insert into mypivot values ('01/14/2014','13:00',6)
insert into mypivot values ('01/14/2014','14:00',4)
insert into mypivot values ('01/14/2014','15:00',3)
insert into mypivot values ('01/14/2014','16:00',1)

select * from mypivot
pivot (max (numcalls)
for [hour] in ([1:00],[2:00],[3:00],[4:00],[5:00],[6:00],[7:00],[9:00],[10:00],[11:00],[12:00],[13:00],[14:00],[15:00],[16:00],[17:00],[18:00],[19:00],[20:00],[21:00],[22:00],[23:00]))

Just wanted to say thanks, with your suggestion I managed to get the query working.

SQL:
Use CallLog

DECLARE @DATEFROM DATETIME
DECLARE @DATETO DATETIME
DECLARE @LIST TABLE (Value VARCHAR(8))
--CREATE TABLE MYPIVOT (MyDate NVARCHAR(10),MyHour NVARCHAR(10),numcalls Int)

Set @DATEFROM	= '2014-01-01T00:00:00'
Set @DATETO		= '2014-01-31T23:59:59'
INSERT INTO @LIST VALUES ('17351')
INSERT INTO @LIST VALUES ('17141')
INSERT INTO @LIST VALUES ('17401')
INSERT INTO @LIST VALUES ('17186')
INSERT INTO @LIST VALUES ('17264')
INSERT INTO @LIST VALUES ('17124')

SELECT		Convert(VarChar, LogDate, 103) As MyDate,
			Convert(VarChar, DatePart(Hour, LogDate)) + ':00' As MyHour,
			COUNT(TermID) As NumCalls
INTO		MYPIVOT
From		Calls
WHERE		Calls.TermID IN (SELECT Value FROM @LIST)
AND			Calls.LogDate BETWEEN @DATEFROM AND @DATETO
GROUP BY	Convert(VarChar, LogDate, 103), DatePart(Hour, LogDate) 


select * from MYPIVOT
pivot (MAX (numcalls) for MyHour in ([9:00],[10:00],[11:00],[12:00],[13:00],[14:00],[15:00],[16:00]) ) as NoCallsPerDay


DROP TABLE MYPIVOT

Now gives me:

Code:
MyDate                         9:00        10:00       11:00       12:00       13:00       14:00       15:00       16:00

14/01/2014                     9           7           4           4           5           4           3           1
15/01/2014                     3           6           8           7           2           6           2           1
