I have a table such as http://sqlfiddle.com/#!6/e4f6f which contains records that need to be reported on an Excel using SSIS.
However, the ordering of records needs to be custom.
Such as below
AID BID CID CurrencyID ClassID Year MetricID Value ReferenceID
220 1 3 6 1147 2012 C1 653465.751842658967 V001
220 1 3 6 1147 2012 C2 0.000000000000 V001
220 1 3 6 1156 2012 C1 1151019.50078003120 V001
220 1 3 6 1156 2012 C2 0.000000000000 V001
As you can see the records are grouped such that they are ordered on ReferenceID first and then all the other dimension keys except the MetricID. Any help is much appreciated
Put MetricID as the last column in your ORDER BY:
SELECT *
FROM [FactValidationResult]
ORDER BY
ReferenceID,
AID,
BID,
CID,
CurrencyID,
Year,
ClassID,
MetricID
I have 2 tables with the following datas in them:-
Company
CompanyId CompanyName
1 Company1
2 Company2
3 Company3
Employees
EmployeeId EmployeeName CompanyId StartDate
1 Employee1 1 12/21/2011
2 Employee2 1 01/20/2012
3 Employee3 2 03/23/2012
4 Employee4 2 07/15/2012
5 Employee5 2 01/20/2013
6 Employee6 3 12/17/2013
Now i want to check, How many people were recruited in the team in the specified month and year? I have the storage table as follows:-
RecruiterIndicator
CompanyId Year Month EmployeeRecruited
1 2011 12 1
1 2012 1 1
2 2012 3 1
2 2012 7 1
2 2013 1 1
3 2013 12 1
This should be a merge stored procedure that should update the data if it is present for the same month year and company and insert if that is not present? The loop would start from a particular date that can be an parameter and it would loop through the current month.
Please help me with this
Thanks

SELECT YEAR(StartDate) AS [Year], MONTH(StartDate) AS [Month], COUNT(*) EmpTotal
FROM Employees
GROUP BY YEAR(StartDate), MONTH(StartDate)
If you want to see the Total Employees by company as well you can do something like this
SELECT YEAR(StartDate) AS [Year], MONTH(StartDate) AS [Month]
,C.CompanyName , COUNT(E.EmployeeId) EmpTotal
FROM Employees E INNER JOIN Company C
ON E.CompanyId = C.CompanyId
GROUP BY YEAR(StartDate), MONTH(StartDate) ,C.CompanyName
Im using Ms SQL database,
My table looks,
SrNo Emp_ID Date Time
------------------------------------
1 25 03-Sep-12 9:35:35 AM
2 25 03-Sep-12 10:31:32 AM
3 25 03-Sep-12 10:34:13 AM
4 25 03-Sep-12 11:05:08 AM
5 25 03-Sep-12 11:08:39 AM
6 25 04-Sep-12 09.05.40 AM
The expected output is
SrNo Emp_ID Date Time Type
---------------------------------------------
1 25 03-Sep-12 9:35:35 AM IN
2 25 03-Sep-12 10:31:32 AM OUT

4 25 03-Sep-12 11:05:08 AM OUT
5 25 03-Sep-12 11:08:39 AM IN
6 25 04-Sep-12 09.05.40 AM IN
For an employee, type "in" and "out" has to be added simultaneously for particular date. For the next date or next /same employee, type has to start with "IN". Can any 1 help me in writing the sql query.
You can achieve this using an additional column
ROW_NUMBER() OVER (PARTITION BY Emp_ID, Date ORDER BY Time) AS RN
then checking modulus 2 on it, if remainder is 1, it's an IN, if it's 0 it's an OUT, based on your requirements.
More specifically
CASE WHEN
ROW_NUMBER() OVER (PARTITION BY Emp_ID, Date ORDER BY Time) % 2 = 1
THEN 'IN'
ELSE 'OUT'
END AS [Type]
I have a query that pulls out month/year totals for customers, and add the ntile ranking. If I were to be able to pull out the max subtotal for ntile 1, 2, 3, 4, and 5, I would ALMOST get what I'm after, but I do not know how to proceed.
For example, the result I want would look something like:
Month Year CustomerCode SubTotal ntile
1 2012 CCC 131.45 1
1 2012 CCC 342.95 2
1 2012 ELITE 643.92 3
1 2012 CCC 1454.05 4
1 2012 CCC 12971.78 5
2 2012 CCC 135.99 1
2 2012 CCI 370.47 2
2 2012 NOC 766.84 3
2 2012 ELITE 1428.26 4
2 2012 VBC 5073.20 5
3 2012 CCC 119.02 1
3 2012 CCC 323.78 2
3 2012 HUCC 759.66 3
3 2012 ELITE 1402.95 4
3 2012 CCC 7964.20 5
EXCEPT - I would expect ranking to be different customers like for month 2, but my base query isn't giving me that result - and I obviously don't know how to get it in T-SQL on SQL SERVER 2005 - in fact I'm not sure what I'm getting.
My next option is to pull a DataTable in C# and do some gymnastics to get there, but there has to be an easier way :)
My base query is
SELECT
i.DateOrdered
,LTRIM(STR(DATEPART(MONTH,i.DateOrdered))) AS [Month]
,LTRIM(STR(YEAR(i.Dateordered))) AS [Year]
,c.CustomerCode
,SUM(i.Jobprice) AS Subtotal
,NTILE(5) OVER(ORDER BY SUM(i.JobPrice)) AS [ntile]
FROM Invoices i
JOIN
Customers c
ON i.CustomerID = c.ID
WHERE i.DateOrdered >= '1/1/2012'
AND i.DateOrdered <= '9/30/2012'
GROUP BY YEAR(i.DateOrdered), MONTH(i.DateOrdered), i.DateOrdered, c.CustomerCode
ORDER BY LTRIM(STR(DATEPART(MONTH,i.DateOrdered))),
TRIM(STR(YEAR(i.Dateordered))),
SUM(i.JobPrice), c.CustomerCode ASC
I'd really appreciate help getting this right.
Thanks in advance

If I read you correctly, what you are after is
For each month in the range,
Show 5 customers who have the greatest SUMs in that month
And against each customer, show the corresponding SUM.
In that case, this SQL Fiddle creates a sample table and runs the query that gives you the output described above. If you wanted to see what's in the created tables, just do simple SELECTs on the right panel.
The query is:
; WITH G as -- grouped by month and customer
(
SELECT DATEADD(D,1-DAY(i.DateOrdered),i.DateOrdered) [Month],
c.CustomerCode,
SUM(i.Jobprice) Subtotal
FROM Invoices i
JOIN Customers c ON i.CustomerID = c.ID
WHERE i.DateOrdered >= '1/1/2012' AND i.DateOrdered <= '9/30/2012'
GROUP BY DATEADD(D,1-DAY(i.DateOrdered),i.DateOrdered), c.CustomerCode
)
SELECT MONTH([Month]) [Month],
YEAR([Month]) [Year],
CustomerCode,
SubTotal,
Rnk [Rank]
FROM
(
SELECT *, RANK() OVER (partition by [Month] order by Subtotal desc) Rnk
FROM G
) X
WHERE Rnk <= 5
ORDER BY Month, Rnk
To explain, the first part (WITH block) is just a fancy way of writing a subquery, that GROUPs the data by month and Customer. The expression DATEADD(D,1-DAY(i.DateOrdered),i.DateOrdered) turns every date into the FIRST day of that month, so that the data can be easily grouped by month. The next subquery written in traditional form adds a RANK column within each month by the subtotal, which is finally SELECTed to give the top 5*.
Note that RANK allows for equal rankings, which may end up showing 6 customers for a month, if 3 of them are ranked equally at position 4. If that is not what you want, then you can change the word RANK to ROW_NUMBER which will randomly tie-break between equal Subtotals.
The query needs to be modified to only get the month and year dateparts. The issue you are having with the same customer showing multiple times in the same month is due to the inclusion of i.DateOrdered in the select and group by clauses.
The following query should give you what you need. Also, I suspect it is a typo on the next to last line of the query, but tsql doesn't have a TRIM() function only LTRIM and RTRIM.
SELECT
LTRIM(STR(DATEPART(MONTH,i.DateOrdered))) AS [Month]
,LTRIM(STR(YEAR(i.Dateordered))) AS [Year]
,c.CustomerCode
,SUM(i.Jobprice) AS Subtotal
,NTILE(5) OVER(ORDER BY SUM(i.JobPrice)) AS [ntile]
FROM Invoices i
JOIN
Customers c
ON i.CustomerID = c.ID
WHERE i.DateOrdered >= '1/1/2012'
AND i.DateOrdered <= '9/30/2012'
GROUP BY YEAR(i.DateOrdered), MONTH(i.DateOrdered), c.CustomerCode
ORDER BY LTRIM(STR(DATEPART(MONTH,i.DateOrdered))),
LTRIM(STR(YEAR(i.Dateordered))),
SUM(i.JobPrice), c.CustomerCode ASC
This gives these results
Month Year CustomerCode Subtotal ntile
1 2012 ELITE 643.92 2
1 2012 CCC 14900.23 5
2 2012 CCC 135.99 1
2 2012 CCI 370.47 1
2 2012 NOC 766.84 3
2 2012 ELITE 1428.26 4
2 2012 VBC 5073.20 4
3 2012 HUCC 759.66 2
3 2012 ELITE 1402.95 3
3 2012 CCC 8407.00 5
Try this:
declare #tab table
(
[month] int,
[year] int,
CustomerCode varchar(20),
SubTotal float
)
insert into #tab
select
1,2012,'ccc',131.45 union all
select
1,2012,'ccc',343.45 union all
select
1,2012,'ELITE',643.92 union all
select

select

select
2,2012,'ELITE',643.92 union all
select
3,2012,'ccc',131.45 union all
select
3,2012,'ccc',343.45 union all
select
3,2012,'ELITE',643.92
;with cte as
(
select NTILE(3) OVER(partition by [month] ORDER BY [month]) AS [ntile],* from #tab
)
select * from cte
Even in your base query you need to add partition by, so that you will get correct output.
I can't see how to solve this problem without double ranking:
You need to get the largest sums per customer & month.
You then need, for every month, to retrieve the top five of the found sums.
Here's how I would approach this:
;
WITH MaxSubtotals AS (
SELECT DISTINCT
CustomerID,
MonthDate = DATEADD(MONTH, DATEDIFF(MONTH, 0, DateOrdered), 0),
Subtotal = MAX(SUM(JobPrice)) OVER (
PARTITION BY Customer, DATEADD(MONTH, DATEDIFF(MONTH, 0, DateOrdered), 0)
ORDER BY SUM(JobPrice)
)
FROM Invoices
GROUP BY
CustomerID,
DateOrdered
),
TotalsRanked AS (
SELECT
CustomerID,
MonthDate,
Subtotal,
Ranking = ROW_NUMBER() OVER (PARTITION BY MonthDate ORDER BY Subtotal DESC)
FROM MaxDailyTotals
)
SELECT
Month = MONTH(i.MonthDate),
Year = YEAR(i.MonthDate),
c.CustomerCode,
i.Subtotal,
i.Ranking
FROM TotalsRanked i
INNER JOIN Customers ON i.CustomerID = c.ID
WHERE i.Ranking <= 5
;
The first CTE, MaxSubtotals, determines the maximum subtotals per customer & month. Involving DISTINCT and a window aggregating function, it is essentially a "shortcut" for the following two-step query:
SELECT
CustomerID,
MonthDate,
Subtotal = MAX(Subtotal)
FROM (
SELECT
CustomerID,
MonthDate = DATEADD(MONTH, DATEDIFF(MONTH, 0, DateOrdered), 0),
Subtotal = SUM(JobPrice)
FROM Invoices
GROUP BY
CustomerID,
DateOrdered
) s
GROUP BY
CustomerID,
MonthDate
The other CTE, TotalsRanked, simply adds ranking numbers for the found susbtotals, partitioning by customer and month. As a final step, you only need to limit the rows to those that have rankings not greater than 5 (or whatever you might choose another time).
Note that using ROW_NUMBER() to rank the rows in this case guarantees that you'll get no more than 5 rows with the Ranking <= 5 filter. If there were two or more rows with the same subtotal, the would get distinct rankings, and in the end you might end up with an output like this:
Month Year CustomerCode Subtotal Ranking
----- ---- ------------ -------- -------
1 2012 CCC 1500.00 1
1 2012 ELITE 1400.00 2
1 2012 NOC 900.00 3
1 2012 VBC 700.00 4
1 2012 HUCC 700.00 5
-- 1 2012 ABC 690.00 6 -- not returned
-- 1 2012 ... ... ...
Even though there might be other customers with Subtotals of 700.00 for the same month, they wouldn't be returned, because they would be assigned rankings after 5.
You could use RANK() instead of ROW_NUMBER() to account for that. But note that you might end up with more than 5 rows per month then, with an output like this:
Month Year CustomerCode Subtotal Ranking
----- ---- ------------ -------- -------
1 2012 CCC 1500.00 1
1 2012 ELITE 1400.00 2
1 2012 NOC 900.00 3
1 2012 VBC 700.00 4
1 2012 HUCC 700.00 4
1 2012 ABC 700.00 4
-- 1 2012 DEF 690.00 7 -- not returned
-- 1 2012 ... ... ...
Customers with subtotals less than 700.00 wouldn't make it to the output because they would have rankings starting with 7, which would correspond to the ranking of the first under-700.00 sum if ranked by ROW_NUMBER().
And there's another option, DENSE_RANK(). You might want to use it if you want up to 5 distinct sums per month in your output. With DENSE_RANK() your output might contain even more rows per month than it would have with RANK(), but the number of distinct subtotals would be exactly 5 (or fewer if the original dataset can't provide you with 5). That is, your output might then look like this:
Month Year CustomerCode Subtotal Ranking
----- ---- ------------ -------- -------
1 2012 CCC 1500.00 1
1 2012 ELITE 1400.00 2
1 2012 NOC 900.00 3
1 2012 VBC 700.00 4
1 2012 HUCC 700.00 4
1 2012 ABC 700.00 4
1 2012 DEF 650.00 5
1 2012 GHI 650.00 5
1 2012 JKL 650.00 5
-- 1 2012 MNO 600.00 5 -- not returned
-- 1 2012 ... ... ...
Like RANK(), the DENSE_RANK() function assigns same rankings to identical values, but, unlike RANK(), it doesn't produce gaps in the ranking sequence.

I have a resultset that looks like this (note [price] is numeric, NULL below represents a
NULL value, the result set is ordered by product_id and timestamp)
product timestamp price
------- ---------------- -----
5678 2008-01-01 12:00 12.34
5678 2008-01-01 12:01 NULL
5678 2008-01-01 12:02 NULL
5678 2008-01-01 12:03 23.45
5678 2008-01-01 12:04 NULL
I want to transform that to a result set that (essentially) copies a non-null value from the latest preceding row, to produce a resultset that looks like this:
product timestamp price
------- ---------------- -----
5678 2008-01-01 12:00 12.34
5678 2008-01-01 12:01 12.34
5678 2008-01-01 12:02 12.34
5678 2008-01-01 12:03 23.45
5678 2008-01-01 12:04 23.45
I don't find any aggregate/windowing function that will allow me to do this (again this ONLY needed for SQL Server 2008 R2.)
I was hoping to find an analytic aggregate function that do this for me, something like...
LAST_VALUE(price) OVER (PARTITION BY product_id ORDER BY timestamp)
But I don't seem to find any way to do a "cumulative latest non-null value" in the window (to bound the window to the preceding rows, rather than the entire partition)
Aside from creating a table-valued user defined function, is there any builtin that would accomplish this?
UPDATE:
Apparently, this functionality is available in the 'Denali' CTP, but not in SQL Server 2008 R2.
LAST_VALUE http://msdn.microsoft.com/en-us/library/hh231517%28v=SQL.110%29.aspx
I just expected it to be available in SQL Server 2008. It's available in Oracle (since 10gR2 at least), and I can do something similar in MySQL 5.1, using a local variable.

I have a table containing the following data. I want to update all nulls in salary columns with previous value without taking null value.
Table:

here is the query that works for me.
select a.*,first_value(a.salary)over(partition by a.value order by a.id) as abc from

Try this:
;WITH SortedData AS
(
SELECT

ROW_NUMBER() OVER(PARTITION BY ProductID ORDER BY TimeStamp DESC) AS 'RowNum'
FROM dbo.YourTable
)
UPDATE SortedData
SET Price = (SELECT TOP 1 Price
FROM SortedData sd2
WHERE sd2.RowNum > SortedData.RowNum
AND sd2.Price IS NOT NULL)
WHERE
SortedData.Price IS NULL
Basically, the CTE creates a list sorted by timestamp (descending) - the newest first. Whenever a NULL is found, the next row that contains a NOT NULL price will be found and that value is used to update the row with the NULL price.
