join two PIVOT table - sql

Question

I have this query
With
NoOfOrder as
(
SELECT Apr,May,Jun,Jul,Aug,Sep,Oct,Nov,Dec,Jan,Feb,Mar
FROM
(
select LEFT(datename(month,InvoiceDate),3) mon,InvoiceNo as InvoiceNo
from tbl_InvoiceMain ,tbl_OrderMain,tbl_CompanyMaster
where tbl_InvoiceMain.OrderID = tbl_OrderMain.OrderID
and (CAST(tbl_InvoiceMain.InvoiceDate AS date) BETWEEN tbl_CompanyMaster.YearStart AND tbl_CompanyMaster.YearEnd)
) P
PIVOT (count(InvoiceNo)for mon in (Jan,Feb,Mar,Apr,May,Jun,Jul,Aug,Sep,Oct,Nov,Dec)) PV
),
OnTime as
(
SELECT Apr,May,Jun,Jul,Aug,Sep,Oct,Nov,Dec,Jan,Feb,Mar
FROM
(
select LEFT(datename(month,InvoiceDate),3) mon,InvoiceNo as InvoiceNo
from tbl_InvoiceMain ,tbl_OrderMain,tbl_CompanyMaster
where tbl_InvoiceMain.OrderID = tbl_OrderMain.OrderID
and (CAST(tbl_InvoiceMain.InvoiceDate AS date) BETWEEN tbl_CompanyMaster.YearStart AND tbl_CompanyMaster.YearEnd)
and CAST(tbl_InvoiceMain.InvoiceDate AS date) <= CAST(tbl_OrderMain.ScheduledDispatchDate AS date)
) P
PIVOT (count(InvoiceNo)for mon in (Jan,Feb,Mar,Apr,May,Jun,Jul,Aug,Sep,Oct,Nov,Dec)) PV
)
Select * From NoOfOrder
union all
Select * From OnTime
It gives this result:
Apr May Jun Jul Aug Sep Oct Nov Dec Jan Feb Mar
18 35 39 52 32 47 47 22 14 0 0 0
9 10 16 22 6 11 19 10 5 0 0 0
Here is my expected result
Apr May Jun Jul Aug Sep Oct Nov Dec Jan Feb Mar
NoOfOrder 18 35 39 52 32 47 47 22 14 0 0 0
OnTimeDelivered 9 10 16 22 6 11 19 10 5 0 0 0
DeliverPerformance% 50.00 28.57 41.03 42.31 18.75 23.40 40.43 45.45 35.71 0.00 0.00 0.00
The formula for DeliverPerformance is:
DeliverPerformance% = (OnTimeDelivered/NoOfOrder) X 100
How do I achieve this result on the next row?

Answer 1

My immediate suggestion is to combine everything first prior to pivoting the results.
Your first query might look like this:
SELECT
LEFT(datename(month, InvoiceDate), 3) InvMon,
SUM(1) AS NoOfOrder,
SUM(CASE WHEN CAST(tbl_InvoiceMain.InvoiceDate AS date) <= CAST(tbl_OrderMain.ScheduledDispatchDate AS date) THEN 1 ELSE 0 END) OnTimeDelivered
FROM tbl_InvoiceMain, tbl_OrderMain, tbl_CompanyMaster
WHERE tbl_InvoiceMain.OrderID = tbl_OrderMain.OrderID
AND (CAST(tbl_InvoiceMain.InvoiceDate AS date) BETWEEN tbl_CompanyMaster.YearStart AND tbl_CompanyMaster.YearEnd)
GROUP BY LEFT(datename(month, InvoiceDate), 3)
Note that I'm always counting every invoice record and optionally counting the "on time" invoices with that CASE statement and the respective SUM functions.
My next thought is to put that query in a CTE and then the statement that uses that CTE will do the additional calculation like so:
SELECT InvMon, NoOfOrder, OnTimeDelivered, ((OnTimeDelivered / NoOfOrder) * 100) DeliverPerformance ...
And finally, that's what I pivot.
