I have a basic query which shows what the latest product to be put in each location (FVTank) is:
SELECT TOP 1
T0.[DateTime],
T0.[TankName],
T1.[Item]
FROM
t005_pci_data T0
INNER JOIN t001_fvbatch T1 ON T1.[FVBatch] = T0.[FVBatch]
WHERE
T0.[TankName] = 'FV101'
UNION
SELECT TOP 1
T0.[DateTime],
T0.[TankName],
T1.[Item]
FROM
t005_pci_data T0
INNER JOIN t001_fvbatch T1 ON T1.[FVBatch] = T0.[FVBatch]
WHERE
T0.[TankName] = 'FV102'
[...etc...]
ORDER BY
T0.[DateTime] DESC
Which gives a result like this:
What I'd like to do is create a summary page on SSRS which would display all the locations which currently hold each item. Ideally it would look something like this:
There are 50 locations and 7 main items so I need it to have 8 headers (one additional one for "other".)
Is there a way to do this in SSRS? Or is there a better solution by doing it in SQL?
Thank you.
Add an additional column to your dataset that calculates a row number for each Item, ordered by the DateTime field:
row_number() over (partition by Item order by DateTime desc) as rn
Judging by your source query in your question, this may be best included as a wrapping select around your final query:
select DateTime
,TankName
,Item
,row_number() over (partition by Item order by DateTime desc) as rn
from(
<Your original query here>
) a
You can then use this as your row group, as without one you will not get the top aligned format you are after in each Item x column. Remember to delete the rn column but keep the grouping:
When you run this report you will get the following format (I didn't bother typing out all your data into my dataset query, hence the missing values):

I have run into an issue I don't know how to solve. I'm working with a MS Access DB.
I have this data:
I want to write a SELECT statement, that gives the following result:
For each combination of Project and Invoice, I want to return the record containing the maximum date, conditional on all records for that combination of Project and Invoice being Signed (i.e. Signed or Date column not empty).
In my head, first I would sort the irrelevant records out, and then return the max date for the remaining records. I'm stuck on the first part.
Could anyone point me in the right direction?
Thanks,
Hulu
Start with an initial query which fetches the combinations of Project, Invoice, Date from the rows you want returned by your final query.
SELECT
y0.Project,
y0.Invoice,
Max(y0.Date) AS MaxOfDate
FROM YourTable AS y0
GROUP BY y0.Project, y0.Invoice
HAVING Sum(IIf(y0.Signed Is Null,1,0))=0;
The HAVING clause discards any Project/Invoice groups which include a row with a Null in the Signed column.
If you save that query as qryTargetRows, you can then join it back to your original table to select the matching rows.
SELECT
y1.Project,
y1.Invoice,
y1.Desc,
y1.Value,
y1.Signed,
y1.Date
FROM
YourTable AS y1
INNER JOIN qryTargetRows AS sub
ON (y1.Project = sub.Project)
AND (y1.Invoice = sub.Invoice)
AND (y1.Date = sub.MaxOfDate);
Or you can do it without the saved query by directly including its SQL as a subquery.
SELECT
y1.Project,
y1.Invoice,
y1.Desc,
y1.Value,
y1.Signed,
y1.Date
FROM
YourTable AS y1
INNER JOIN
(
SELECT y0.Project, y0.Invoice, Max(y0.Date) AS MaxOfDate
FROM YourTable AS y0
GROUP BY y0.Project, y0.Invoice
HAVING Sum(IIf(y0.Signed Is Null,1,0))=0
) AS sub
ON (y1.Project = sub.Project)
AND (y1.Invoice = sub.Invoice)
AND (y1.Date = sub.MaxOfDate);
Write A SQL query, which should be possible in MS-Access too, like this:
SELECT
Project,
Invoice,
MIN([Desc]) Descriptions,
SUM(Value) Value,
MIN(Signed) Signed,
MAX([Date]) "Date"
FROM data
WHERE Signed<>'' AND [Date]<>''
GROUP BY
Project,
Invoice
output:
Project
Invoice
Descriptions
Value
Signed
Date

Note: for invoice 1 on project A, you will see a value of 300, which is the total for that invoice (when grouping on Project='A' and Invoice=1).
Maybe I should have used DCONCAT (see: Concatenation in between records in Access Query ) for the Description, to include 'TV' in it. But I am unable to test that so I am only referring to this answer.
Try joining a second query:
Select *
From YourTable As T
Inner Join
(Select Project, Invoice, Max([Date]) As MaxDate
From YourTable
Group By Project, Invoice) As S
On T.Project = S.Project And T.Invoice = S.Invoice And T.Date = S.MaxDate
I need to update the following query so that it only returns one child record (remittance) per parent (claim).
Table Remit_To_Activate contains exactly one date/timestamp per claim, which is what I wanted.
But when I join the full Remittance table to it, since some claims have multiple remittances with the same date/timestamps, the outermost query returns more than 1 row per claim for those claim IDs.
SELECT * FROM REMITTANCE
WHERE BILLED_AMOUNT>0 AND ACTIVE=0
AND REMITTANCE_UUID IN (
SELECT REMITTANCE_UUID FROM Claims_Group2 G2
INNER JOIN Remit_To_Activate t ON (
(t.ClaimID = G2.CLAIM_ID) AND
(t.DATE_OF_LATEST_REGULAR_REMIT = G2.CREATE_DATETIME)
)
where ACTIVE=0 and BILLED_AMOUNT>0
)
I believe the problem would be resolved if I included REMITTANCE_UUID as a column in Remit_To_Activate. That's the REAL issue. This is how I created the Remit_To_Activate table (trying to get the most recent remittance for a claim):
SELECT MAX(create_datetime) as DATE_OF_LATEST_REMIT,
MAX(claim_id) AS ClaimID,
INTO Latest_Remit_To_Activate
FROM Claims_Group2
WHERE BILLED_AMOUNT>0
GROUP BY Claim_ID
ORDER BY Claim_ID
Claims_Group2 contains these fields:
REMITTANCE_UUID,
CLAIM_ID,
BILLED_AMOUNT,
CREATE_DATETIME
Here are the 2 rows that are currently giving me the problem--they're both remitts for the SAME CLAIM, with the SAME TIMESTAMP. I only want one of them in the Remits_To_Activate table, so only ONE remittance will be "activated" per Claim:
enter image description here
You can change your query like this:
SELECT
p.*, latest_remit.DATE_OF_LATEST_REMIT
FROM
Remittance AS p inner join
(SELECT MAX(create_datetime) as DATE_OF_LATEST_REMIT,
claim_id,
FROM Claims_Group2
WHERE BILLED_AMOUNT>0
GROUP BY Claim_ID
ORDER BY Claim_ID) as latest_remit
on latest_remit.claim_id = p.claim_id;
This will give you only one row. Untested (so please run and make changes).
Without having more information on the structure of your database -- especially the structure of Claims_Group2 and REMITTANCE, and the relationship between them, it's not really possible to advise you on how to introduce a remittance UUID into DATE_OF_LATEST_REMIT.
Since you are using SQL Server, however, it is possible to use a window function to introduce a synthetic means to choose among remittances having the same timestamp. For example, it looks like you could approach the problem something like this:
select *
from (
select
r.*,
row_number() over (partition by cg2.claim_id order by cg2.create_datetime desc) as rn
from
remittance r
join claims_group2 cg2
on r.remittance_uuid = cg2.remittance_uuid
where
r.active = 0
and r.billed_amount > 0
and cg2.active = 0
and cg2.billed_amount > 0
) t
where t.rn = 1
Note that that that does not depend on your DATE_OF_LATEST_REMIT table at all, it having been subsumed into the inline view. Note also that this will introduce one extra column into your results, though you could avoid that by enumerating the columns of table remittance in the outer select clause.
It also seems odd to be filtering on two sets of active and billed_amount columns, but that appears to follow from what you were doing in your original queries. In that vein, I urge you to check the results carefully, as lifting the filter conditions on cg2 columns up to the level of the join to remittance yields a result that may return rows that the original query did not (but never more than one per claim_id).
A co-worker offered me this elegant demonstration of a solution. I'd never used "over" or "partition" before. Works great! Thank you John and Gaurasvsa for your input.

My SQL experience is fairly minimal so please go easy on me here. I have a table tblForEx and I'm trying to create a query that looks at one particular column LastSalesRateChangeDate and also ForExRate.
Basically what I want to do is for the query to check that LastSalesRateChangeDate and then pull the ForExRate that is on the same line (obviously in the ForExRate column), then I need to check to see if there is a +/- 5% change since the last time the LastSalesRateChangeDate changed. I hope this makes sense, I tried to explain it as clearly as possible.
I believe I would need to create a 'subquery' to look at the LastSalesRateChangeDate and pull the ForEx rate from that date, but I just don't know how to go about this.
I should add this is being done in Access (SQL)
Sample data, here is what the table looks like:
| BaseCur | ForCur | ForExRate | LastSalesRateChangeDate
| USD | BRL | 1.718 | 12/9/2008
| USD | BRL | 1.65 | 11/8/2008
So I would need a query to look at the LastSalesRateChangeDate column, check to see if the date has changed, if so take the ForExRate value and then give a percentage difference of that ForExRate value since the last record.
So the final result would likely look like
"BaseCur" "ForCur" "Percentage Change since Last Sales Rate Change"
USD BRL X%
Gordon's answer pointed in the right direction:
SELECT t2.*, (SELECT top 1 t.ForExRate
FROM tblForEx t
where t.BaseCur=t2.BaseCur AND t.ForCur=t2.ForCur and t.LastSalesRateChangeDate<t2.LastSalesRateChangeDate
order by t.LastSalesRateChangeDate DESC, t.ForExRate DESC
) AS PreviousRate, [ForExRate]/[PreviousRate]-1 AS ChangeRatio
FROM tblForEx AS t2;
Access gives errors where the TOP 1 in the subquery causes "ties". We broke the ties and therefore removed the error by adding an extra item to the ORDER BY clause. To get the ratio to display as a percentage, switch to the design view and change the properties of that column accordingly.
If I understand correctly, you want the previous value. In MS Access, you can use a correlated subquery:
select t.*,
(select top (1) t2.LastSalesRateChangeDate
from tblForEx as t2
where t2.BaseCur = t.BaseCur and t2.ForCur = t.ForCur
t2.LastSalesRateChangeDate < t.LastSalesRateChangeDate
order by t2.LastSalesRateChangeDate desc
) as prev_LastSalesRateChangeDate
from t;
Now, with this as a subquery, you can get the previous exchange rate using a join:
select t.*, ( (t.ForExRate / tprev.ForExRate) - 1) as change_ratio
from (select t.*,
(select top (1) t2.LastSalesRateChangeDate
from tblForEx as t2
where t2.BaseCur = t.BaseCur and t2.ForCur = t.ForCur
t2.LastSalesRateChangeDate < t.LastSalesRateChangeDate
order by t2.LastSalesRateChangeDate desc
) as prev_LastSalesRateChangeDate
from t
) as t inner join
tblForEx as tprev
on tprev.BaseCur = t.BaseCur and tprev.ForCur = t.ForCur
tprev.LastSalesRateChangeDate = t.prev_LastSalesRateChangeDate;
As per my understanding, you can use LEAD function to get last changed date Rate in a new column by using below query:
WITH CTE AS (
SELECT *, LEAD(ForExRate, 1) OVER(PARTITION BY BaseCur, ForCur ORDER BY LastChangeDate DESC) LastValue
FROM #TT
)
SELECT BaseCur, ForCur, ForExRate, LastChangeDate , CAST( ((ForExRate - ISNULL(LastValue, 0))/LastValue)*100 AS float)
FROM CTE
Problem here is:
for every last row in group by you will have new calculalted column which we have made using LEAD function.
If there is only a single row for a particular BaseCur and ForCur, then also you will have NULL in column.
Resolution:
If you are sure that there will be at least two rows for each BaseCur and ForCur, then you can use WHERE clause to remove NULL values in final result.
WITH CTE AS (
SELECT *, LEAD(ForExRate, 1) OVER(PARTITION BY BaseCur, ForCur ORDER BY LastChangeDate DESC) LastValue
FROM #TT
)
SELECT BaseCur, ForCur, ForExRate, LastChangeDate , CAST( ((ForExRate - ISNULL(LastValue, 0))/LastValue)*100 AS float) Percentage
FROM CTE
WHERE LastValue IS NOT NULL
SELECT basetbl.BaseCur, basetbl.ForCur, basetbl.NewDate, basetbl.OldDate, num2.ForExRate/num1.ForExRate*100 AS PercentChange FROM
(((SELECT t.BaseCur, t.ForCur, MAX(t.LastSalesRateChangeDate) AS NewDate, summary.Last_Date AS OldDate
FROM (tblForEx AS t
LEFT JOIN (SELECT TOP 2 BaseCur, ForCur, MAX(LastSalesRateChangeDate) AS Last_Date FROM tblForEx AS t1
WHERE LastSalesRateChangeDate <>
(SELECT MAX(LastSalesRateChangeDate) FROM tblForEx t2 WHERE t2.BaseCur = t1.BaseCur AND t2.ForCur = t1.ForCur)
GROUP BY BaseCur, ForCur) AS summary
ON summary.ForCur = t.ForCur AND summary.BaseCur = t.BaseCur)
GROUP BY t.BaseCur, t.ForCur, summary.Last_Date) basetbl
LEFT JOIN tblForEx num1 ON num1.BaseCur=basetbl.BaseCur AND num1.ForCur = basetbl.ForCur AND num1.LastSalesRateChangeDate = basetbl.OldDate))
LEFT JOIN tblForEx num2 ON num2.BaseCur=basetbl.BaseCur AND num2.ForCur = basetbl.ForCur AND num2.LastSalesRateChangeDate = basetbl.NewDate;
This uses a series of subqueries. First, you are selecting the most recent date for the BaseCur and ForCur. Then, you are joining onto that the previous date. I do that by using another subquery to select the top two dates, and exclude the one that is equal to the previously established most recent date. This is the "summary" subquery.
Then, you get the BaseCur, ForCur, NewDate, and OldDate in the "basetbl" subquery. After that, it is two simple joins of the original table back onto those dates to get the rate that was applicable then.
Finally, you are selecting your BaseCur, ForCur, and whatever formula you want to use to calculate the rate change. I used a simple ratio in that one, but it is easy to change. You can remove the dates in the first line if you want, they are there solely as a reference point.
It doesn't look pretty, but complicated Access SQL queries never do.
Query:
SELECT *
FROM [MemberBackup].[dbo].[OriginalBackup]
where ration_card_id in
(
1247881,174772,
808454,2326154
)
Right now the data is ordered by the auto id or whatever clause I'm passing in order by.
But I want the data to come in sequential format as per id's I have passed
Expected Output:
All Data for 1247881
All Data for 174772
All Data for 808454
All Data for 2326154
Note:
Number of Id's to be passed will 300 000
One option would be to create a CTE containing the ration_card_id values and the orders which you are imposing, and the join to this table:
WITH cte AS (
SELECT 1247881 AS ration_card_id, 1 AS position
UNION ALL
SELECT 174772, 2
UNION ALL
SELECT 808454, 3
UNION ALL
SELECT 2326154, 4
)
SELECT t1.*
FROM [MemberBackup].[dbo].[OriginalBackup] t1
INNER JOIN cte t2
ON t1.ration_card_id = t2.ration_card_id
ORDER BY t2.position DESC
Edit:
If you have many IDs, then neither the answer above nor the answer given using a CASE expression will suffice. In this case, your best bet would be to load the list of IDs into a table, containing an auto increment ID column. Then, each number would be labelled with a position as its record is being loaded into your database. After this, you can join as I have done above.
If the desired order does not reflect a sequential ordering of some preexisting data, you will have to specify the ordering yourself. One way to do this is with a case statement:
SELECT *
FROM [MemberBackup].[dbo].[OriginalBackup]
where ration_card_id in
(
1247881,174772,
808454,2326154
)
ORDER BY CASE ration_card_id
WHEN 1247881 THEN 0
WHEN 174772 THEN 1
WHEN 808454 THEN 2
WHEN 2326154 THEN 3
END
Stating the obvious but note that this ordering most likely is not represented by any indexes, and will therefore not be indexed.
Insert your ration_card_id's in #temp table with one identity column.
Re-write your sql query as:
SELECT a.*
FROM [MemberBackup].[dbo].[OriginalBackup] a
JOIN #temps b
on a.ration_card_id = b.ration_card_id
order by b.id
I have a query:
;with date_cte as(
SELECT r.starburst_dept_name,r.monthly_past_date as PrevDate,x.monthly_past_date as CurrDate,r.starburst_dept_average - x.starburst_dept_average as Average
FROM
(
SELECT *,ROW_NUMBER() OVER(PARTITION BY starburst_dept_name ORDER BY monthly_past_date) AS rowid
FROM intranet.dbo.cse_reports_month
) r
JOIN
(
SELECT *,ROW_NUMBER() OVER(PARTITION BY starburst_dept_name ORDER BY monthly_past_date) AS rowid
FROM intranet.dbo.cse_reports_month
Where month(monthly_past_date) > month(DATEADD(m,-2,monthly_past_date))
) x
ON r.starburst_dept_name = x.starburst_dept_name AND r.rowid = x.rowid+1
Where r.starburst_dept_name is NOT NULL
)
Select *
From date_cte
Order by Average DESC
So doing some testing, I have alter some columns data, to see why it gives me certain information. I don't know why when I run the query it gives my a date column that should not be there from "january" (row 4) like the picture below:
The database has more data that has the same exact date '2014-01-25 00:00:00.000', so I'm not sure why it would only get that row and compare the average?
I did before I run the query alter the column in that row and change the date? But I'm not sure if that would have something to do with it.
UPDATE:
I have added the sqlfinddle,
What I would like to get it subtract the average
from last_month - last 2 month ago.
It Was actually working until I made a change and alter the data.
I made the changes to test a certain situation, which obviously lead
to learning that there are flaws to the query.
Based on your SQL Fiddle, this eliminates joins from prior than month-2 from showing up.
SELECT
thismonth.starburst_dept_name
,lastmonth.monthtly_past_date [PrevDate]
,thismonth.monthtly_past_date [CurrDate]
,thismonth.starburst_dept_average - lastmonth.starburst_dept_average as Average
FROM dbo.cse_reports thismonth
inner join dbo.cse_reports lastmonth on
thismonth.starburst_dept_name = lastmonth.starburst_dept_name
AND month(DATEADD(MONTH,-1,thismonth.monthtly_past_date))=month(lastmonth.monthtly_past_date)
WHERE MONTH(thismonth.monthtly_past_date)=month(DATEADD(MONTH,-1,GETDATE()))
Order by thismonth.starburst_dept_average - lastmonth.starburst_dept_average DESC
