SQL Server : pivot or not to pivot - sql-server

Question

I have a table in which I run a select statement and returns the following data
Name date skill seconds calls
----------------------------------------------
bob 9/2/2016 706 12771 56
bob 9/2/2016 707 4061 16
bob 9/2/2016 708 2577 15
bob 9/2/2016 709 2156 6
I want to return like below one row of data:
Name date 706sec 706call 707sec 707call 708sec 708call 709sec 709call
----------------------------------------------------------------------------------
bob 9/2/2016 12771 56 4061 16 2577 15 2156 6
My first attempt was a pivot but does not return a single row:
Select
name, date, seconds, calls, [706], [707],[708],[709],
from
(Select
name, date, skill, seconds, calls
From
tablecalls
Where
date between '09/02/2016 00:00' and '09/02/2016 23:59'
and name = 'bob') as b
pivot
(sum(seconds) for skill in ([706], [707], [708], [709] )) as p1
This returns:
name date calls 706sec 707sec 708sec 709sec
---------------------------------------------------------
bob 9/2/2016 6 NULL NULL NULL 2156
bob 9/2/2016 15 NULL NULL 2577 NULL
bob 9/2/2016 16 NULL 4061 NULL NULL
bob 9/2/2016 56 12771 NULL NULL NULL
Maybe PIVOT is not the right way to do this. Is there another way?

Answer 1

can you format your data in question. I am not sure whether I get youe point?
CREATE TABLE #tt([name] VARCHAR(10),[date] DATE,skill INT,seconds INT, calls int )
INSERT INTO #tt
SELECT 'bob','9/2/2016',706,12771,56 UNION all
SELECT 'bob','9/2/2016',707,4061,16 UNION all
SELECT 'bob','9/2/2016',708,2577,15 UNION all
SELECT 'bob','9/2/2016',709,2156,6
SELECT * FROM (
SELECT t.name,t.date,c.* FROM #tt AS t
CROSS APPLY(VALUES(LTRIM(t.skill)+'sec',t.seconds),(LTRIM(t.skill)+'calls',t.seconds)) c(t,v)
) AS A
PIVOT(MAX(v) FOR t IN ([706sec],[706calls],[707sec],[707calls],[708sec],[708calls],[709sec],[709calls])) p
name date 706sec 706calls 707sec 707calls 708sec 708calls 709sec 709calls
---------- ---------- ----------- ----------- ----------- ----------- ----------- ----------- ----------- -----------
bob 2016-09-02 12771 12771 4061 4061 2577 2577 2156 2156
if the count of skill is not fix, you can use dynamic script：
DECLARE #col VARCHAR(max),#sql VARCHAR(max)
SELECT #col=ISNULL(#col+',[','[')+LTRIM(skill)+'sec],['+LTRIM(skill)+'calls]' FROM #tt GROUP BY skill
SET #sql='
SELECT * FROM (
SELECT t.name,t.date,c.* FROM #tt AS t
CROSS APPLY(VALUES(LTRIM(t.skill)+''sec'',t.seconds),(LTRIM(t.skill)+''calls'',t.seconds)) c(t,v)
) AS A
PIVOT(MAX(v) FOR t IN ('+#col+')) p'
EXEC (#sql)
