Hi,
I have a Phone Log table consist of CalledBy and CallOn.
I am trying to write a query that show each sales person calls per week.
The data looks like this

Bob Smith     1/7/2014
Bob Smith     1/8/2014
Bob Smith     1/17/2014
Mary Jane      1/8/2014
Mary Jane      1/9/2014

I want the result to look like this

Name           TotalCallsInWeekOf1/7/2014    TotalCallsInWeekOf1/14/2014
Bob Smith                            2                                             1
Mary Jane                             1                                             0

I have a query in progress but it doesn't really do what I needed.
Please help!

Select
A.CalledBy,
A.WeekOf,
sum(A.calls) AS NumOfCallsMade
from
(
    SELECT
    CONVERT(varchar, DATEADD(dd, -(DATEPART(dw, CalledOn)-2), CalledOn), 101) AS WeekOf,
    CalledBy
    ,1 AS calls
    FROM PhoneLog
   
) A
GROUP BY CalledBy, WeekOf
ORDER BY CalledBy, WeekOf

For just two weeks specifically, the code below should work ok.

If you really need the actual date in the column name, you will have to use dynamic SQL or a temp table for the results.



DROP TABLE #PhoneLog
CREATE TABLE #PhoneLog (
    CalledBy varchar(30),
    CalledOn datetime
    )
INSERT INTO #PhoneLog VALUES('Bob Smith',     '1/5/2014') --should be ignored, before start date
INSERT INTO #PhoneLog VALUES('Bob Smith',     '1/6/2014') --should be ignored, before start date
INSERT INTO #PhoneLog VALUES('Bob Smith',     '1/7/2014')
INSERT INTO #PhoneLog VALUES('Bob Smith',     '1/8/2014')
INSERT INTO #PhoneLog VALUES('Bob Smith',     '1/17/2014')
INSERT INTO #PhoneLog VALUES('Bob Smith',     '1/22/2014') --should be ignored, after start date + 2 weeks
INSERT INTO #PhoneLog VALUES('Mary Jane',     '1/8/2014')
INSERT INTO #PhoneLog VALUES('Mary Jane',     '1/9/2014')


DECLARE @start_date datetime
SET @start_date = '20140107'

----------------------------------------------------------------------------------------------------

SELECT
    pl.CalledBy AS Name,
    SUM(CASE WHEN pl.CalledOn >= @start_date AND pl.CalledOn < DATEADD(DAY, 8, @start_date) THEN 1 ELSE 0 END) AS Week1,
    SUM(CASE WHEN pl.CalledOn >= DATEADD(DAY, 7, @start_date) AND pl.CalledOn < DATEADD(DAY, 15, @start_date) THEN 1 ELSE 0 END) AS Week2
FROM #PhoneLog pl --dbo.PhoneLog pl
WHERE
    pl.CalledOn >= @start_date AND
    pl.CalledOn < DATEADD(DAY, 15, @start_date)
GROUP BY
    pl.CalledBy
0
