Convert multiple Rows into Columns EDIT - sql

Question

OK. I edit my question. This is my script:
CREATE TABLE #Table (
Data Date,
Max_Temp Real,
Min_Temp Real,
Sr_Temp Real,
Sr_Temp_work Real)
SET NOCOUNT ON
DECLARE #StartTime Time
DECLARE #EndTime Time
DECLARE #StartTime1 Time
DECLARE #EndTime1 Time
DECLARE #data_start Date
DECLARE #data_stop Date
DECLARE #Data Date
DECLARE #Data_stop_while Date
DECLARE #Max_Temp Real
DECLARE #Min_Temp Real
DECLARE #Sr_Temp Real
DECLARE #Sr_Temp_work Real
SET #data_start = '20140713'
SET #data_stop = '20140719'
SET #StartTime = '00:00:00.000'
SET #EndTime = '23:59:59.998'
SET #StartTime1 = '08:00:00.000'
SET #EndTime1 = '16:30:00.000'
Set NOCOUNT OFF
SELECT #Data = #data_start
SELECT #Data_stop_while = DATEADD(day,1,#data_stop)
WHILE (#Data_stop_while<>#Data)
BEGIN
SELECT #Max_Temp = MAX(Value), #Min_Temp = MIN(Value), #Sr_Temp = AVG(Value) FROM INSQL.Runtime.dbo.History WHERE TagName IN ('VariableName')
and wwRetrievalMode = 'Cyclic'
AND DateTime >= (#Data + cast(#StartTime as datetime))
AND DateTime <= (#Data + cast(#EndTime as datetime))
SELECT #Sr_Temp_work = AVG(Value) FROM INSQL.Runtime.dbo.History WHERE TagName IN ('VariableName')
and wwRetrievalMode = 'Cyclic'
AND DateTime >= (#Data + cast(#StartTime1 as datetime))
AND DateTime <= (#Data + cast(#EndTime1 as datetime))
INSERT INTO #Table(Data, Max_Temp, Min_Temp, Sr_Temp, Sr_Temp_work) VALUES (#Data, #Max_Temp, #Min_Temp, #Sr_Temp, #Sr_Temp_work)
SELECT #Data = DATEADD(day,1,#Data)
END
SELECT Data, Max_Temp, Min_Temp, Sr_Temp, Sr_Temp_work FROM #Table GO
When I set a specific time interval, I have those tables and now I need convert this table:
I used pivot, unpivot and any links with forums and I can't do it...

Answer 1

Actually you need to use dynamic pivot and unpivot together. Check the following query. Use the following code in place of the last select query in your procedure
DECLARE #Columns NVARCHAR(MAX)
DECLARE #MainQuery NVARCHAR(MAX)
SELECT #Columns = ISNULL( #Columns + ',','') + QUOTENAME(CONVERT(VARCHAR(10),Data,20))
FROM (SELECT DISTINCT Data FROM #Table) C
SET #MainQuery ='SELECT [Temperature],' + #Columns + '
FROM
(
SELECT Data,Max_Temp,Min_Temp,Sr_Temp,Sr_Temp_work
FROM #Table
) as T
UNPIVOT
(
Value FOR [Temperature] in (Max_Temp,Min_Temp,Sr_Temp,Sr_Temp_work)
) AS U
PIVOT
(
MAX(Value) FOR [Data] IN ('+ #Columns +')
) as P
'
EXEC sp_executesql #MainQuery

Answer 2

It's not by far the most elegant solution but with some dynamic SQL you should be able to replicate the logic.
DECLARE #temp TABLE (
Data DATE,
Max_temp FLOAT,
Min_Temp FLOAT,
Sr_Temp FLOAT,
Sr_Temp_work FLOAT
)
INSERT INTO #temp
select
*
from (values
('2014-07-13',25.8,25.6,25.701,25.668),
('2014-07-14',26.8,26.6,26.701,26.668),
('2014-07-15',27.8,27.6,27.701,27.668),
('2014-07-16',28.8,28.6,28.701,28.668))T (Data,Max_temp,Min_Temp,Sr_Temp, Sr_Temp_work)
SELECT
Data,
Max_temp,
Min_Temp,
Sr_Temp,
Sr_Temp_work

SELECT

ON A DIFFERENT NOTE!
Dont use row by row..
DECLARE
#data_start Date = '2014-07-13',
#data_stop Date = '2014-07-19'
SELECT
[DateTime] Data
MAX(Value) Max_temp,
MIX(Value) Min_temp,
AVG(Value) Sr_Temp
AVG(case when CONVERT(TIME(7),DateTime) between '08:00:00.000' and '16:30:00.000' then Value else NULL end) Sr_Temp_work
FROM INSQL.Runtime.dbo.History
WHERE
TagName IN ('VariableName') and
wwRetrievalMode = 'Cyclic' AND
CONVERT(DATE, Datetime) between #data_start and #data_stop
