Pivot Rows to Column with SUM if Hours between two Time Value - sql-server

Question

Im using MS SQL Server 2008
Table name is tblDateTimeLog:
ID INT(AI)
RecordID INT
DateLog DATE
TimeLog TIME
DetachmentCode INT
EntryDate DATETIME
IsDeleted BIT
UserID VARCHAR(50)
I have a table containing this:
RecordID | DateLog | TimeLog
11 | 2013-06-01 | 07:59:00
11 | 2013-06-01 | 19:01:00
11 | 2013-06-02 | 07:57:00
11 | 2013-06-02 | 19:03:00
11 | 2013-06-03 | 07:49:00
11 | 2013-06-03 | 19:11:00
14 | 2013-06-04 | 08:01:00
14 | 2013-06-04 | 19:03:00
14 | 2013-06-05 | 07:52:00
14 | 2013-06-05 | 19:02:00
One Record ID can have multiple TimeLog on the same DateLog
Now I want it to show like this:
The Dates as columns and the Total No. of Hours between MIN(TimeLog) and MAX(TimeLog)
RecordID | 2013-06-01 | 2013-06-02 | 2013-06-03 | 2013-06-04 | 2013-06-05
11 | 11:02:00 | 11:06:00 | 11:22:00 | NULL | NULL
14 | NULL | NULL | NULL | 11:02:00 | 11:10:00
As per Mikael's Answer, this works but as I understand his query, this returns MIN(TimeLog):
DECLARE #SQL NVARCHAR(MAX)
DECLARE #ColumnList NVARCHAR(MAX)
SELECT #ColumnList =
STUFF
(
(
SELECT DISTINCT ','+QUOTENAME(DateLog)
FROM TESTPIS.dbo.tblDateTimeLog
WHERE IsDeleted=0 AND DateLog >= '2013-06-15' AND DateLog <= '2013-06-30'
ORDER BY 1
FOR XML PATH('')
), 1, 1, ''
)
SET #SQL = 'SELECT P.RecordID, '+#ColumnList+'
FROM
(
SELECT RecordID, TimeLog, DateLog FROM TESTPIS.dbo.tblDateTimeLog WHERE isDeleted=0
) AS T
PIVOT
(
MIN(TimeLog) FOR DateLog IN ('+#ColumnList+')
) as P'
EXEC (#SQL)
What I want to return is like DATEDIFF(MINUTES,MIN(TimeLog),MAX(TimeLog)
I tried replacing the MIN(TimeLog) in the query with this
SUM(DATEDIFF(MINUTES,MIN(TimeLog),MAX(TimeLog))
However, I got this error
Incorrect syntax near '('.

Answer 1

select P.RecordID,
P.[2013-06-01],
P.[2013-06-02],
P.[2013-06-03],
P.[2013-06-04],
P.[2013-06-05]
from (
select RecordID,
TimeLog,
DateLog
from YourTable
) as T
pivot(min(TimeLog) for DateLog in ([2013-06-01],
[2013-06-02],
[2013-06-03],
[2013-06-04],
[2013-06-05])) as P
To build the query dynamically you have to first figure out what the column list should contain.
select distinct DateLog
from YourTable
order by 1
The result from that query has to be turned into a comma separated list and since numbers like that is invalid column names you can use quotename() to enclose the value in [].
To build the comma separated list of column you can use for xml path('').
select stuff((select distinct ','+quotename(DateLog)
from YourTable
order by 1
for xml path('')), 1, 1, '')
stuff() is there to remove the first comma.
Then you just need to put it all together and execute the query you have built.
declare #SQL nvarchar(max)
declare #ColumnList nvarchar(max)
select #ColumnList = stuff((select distinct ','+quotename(DateLog)
from YourTable
order by 1
for xml path('')), 1, 1, '')
set #SQL = '
select P.RecordID, '+#ColumnList+'
from (
select RecordID,
TimeLog,
DateLog
from YourTable
) as T
pivot(min(TimeLog) for DateLog in ('+#ColumnList+')) as P'
exec (#SQL)

Update
To get the diff between max and min timelog value for each day you can do a group by on RecordID and DateLog in the derived table and calculate the diff in seconds between min and max and use that value to calculate a new time value using dateadd.
select P.RecordID,
P.[2013-06-01],
P.[2013-06-02],
P.[2013-06-03],
P.[2013-06-04],
P.[2013-06-05]
from (
select RecordID,
dateadd(second, datediff(second, min(TimeLog), max(TimeLog)), convert(time(0), '00:00')) as TimeDiff,
DateLog
from YourTable
group by RecordID,
DateLog
) as T
pivot(min(TimeDiff) for DateLog in ([2013-06-01],
[2013-06-02],
[2013-06-03],
[2013-06-04],
[2013-06-05])) as P
Dynamic version:
declare #SQL nvarchar(max)
declare #ColumnList nvarchar(max)
select #ColumnList = stuff((select distinct ','+quotename(DateLog)
from YourTable
order by 1
for xml path('')), 1, 1, '')
set #SQL = '
select P.RecordID, '+#ColumnList+'
from (
select RecordID,
dateadd(second, datediff(second, min(TimeLog), max(TimeLog)), convert(time(0), ''00:00'')) as TimeDiff,
DateLog
from YourTable
group by RecordID,
DateLog
) as T
pivot(min(TimeDiff) for DateLog in ('+#ColumnList+')) as P'
exec (#SQL)

Answer 2

Try this one -
Query:
IF OBJECT_ID (N'tempdb.dbo.#temp') IS NOT NULL
DROP TABLE #temp
CREATE TABLE #temp
(
RecordID INT
, DateLog DATETIME
, TimeLog TIME
)
INSERT INTO #temp (RecordID, DateLog, TimeLog)
VALUES
(11, '2013-06-01', '08:00:00'), (11, '2013-06-02', '09:00:00'),
(11, '2013-06-03', '10:00:00'), (11, '2013-06-04', '11:00:00'),
(11, '2013-06-05', '12:00:00'), (14, '2013-06-01', '13:00:00'),
(14, '2013-06-02', '14:00:00'), (14, '2013-06-03', '15:00:00'),
(14, '2013-06-04', '16:00:00')
DECLARE #SQL NVARCHAR(MAX)
SELECT #SQL = 'SELECT *
FROM (
SELECT DateLog, RecordID, tt = CAST(TimeLog AS VARCHAR(8))
FROM #temp
) src
PIVOT (
MAX(tt)
FOR DateLog IN (' + STUFF((
SELECT ', [' + CONVERT(VARCHAR(10), DateLog, 120) + ']'
FROM #temp
GROUP BY DateLog
ORDER BY DateLog
FOR XML PATH(''), TYPE).value('.', 'NVARCHAR(MAX)'), 1, 2, '') + ')
) p'
PRINT #SQL
EXEC sys.sp_executesql #SQL
Output:
SELECT *
FROM (
SELECT DateLog, RecordID, tt = CAST(TimeLog AS VARCHAR(8))
FROM #temp
) src
PIVOT (
MAX(tt)
FOR DateLog IN ([2013-06-01], [2013-06-02], [2013-06-03], [2013-06-04], [2013-06-05])
) p
Results:
RecordID 2013-06-01 2013-06-02 2013-06-03 2013-06-04 2013-06-05
----------- ---------- ---------- ---------- ---------- ----------
11 08:00:00 09:00:00 10:00:00 11:00:00 12:00:00
14 13:00:00 14:00:00 15:00:00 16:00:00 NULL
Update with results:
