Transact SQL :: Efficient Way To Calculate Unique Values?
Jul 14, 2015
I have a data set as -
ID Set Date DB Date
100 Null 07/01/15
100 07/05/15 07/02/15
100 07/10/15 07/08/15
I want to able to get 2 unique dates
1. 07/02/15 - As I want the DB date for ID - 100 when set date changed from a null value to non null value.
2. 07/08/15 - As I want the DB date for ID - 100 when a non null set date changes.
The table has such records for lot of different ID's.

I'm trying to use merge data from a staging table to a production table. There are a lot of duplicate values for serverName and I only want to insert one instance where there are duplicates.
How I can adapt the code I have so far to achieve this?
MERGE tblServer AS TARGET
USING tblTemp AS SOURCE
ON (TARGET.serverName = SOURCE.serverName)
WHEN MATCHED THEN
UPDATE SET TARGET.serverName = SOURCE.serverName, TARGET.serverLocation = SOURCE.serverLocation
WHEN NOT MATCHED BY TARGET THEN
INSERT (serverName, serverLocation)
VALUES (SOURCE.serverName, SOURCE.serverLocation)
WHEN NOT MATCHED BY SOURCE THEN
DELETE;

I have the following two tables...
tblServer
-serverID
-serverName
-serverLocation
tblSite
-siteID
-serverID
-siteName
-siteIpAddress
I need to write a select query that gets the values of all columns but only returns unique sites because some sites are load balanced across several servers and where this is the case I don't want the site to appear multiple times in the list.

SELECT '100','Inplace','01/05/2015 05:00' UNION ALL
SELECT '100','Removed','03/05/2015 10:00' UNION ALL
SELECT '100','Inplace','05/05/2015 10:41' UNION ALL
[Code] ....
I need an output to look like on each day how many events were in place.
E.g.: for the month on May , Event_id 100 was inplace on 1st and removed on 3rd , so on 1st may 2 event_ids (100, 103) hence 2 .
event_ids - 103 / 104 and inplace the whole month and not removed. so its calculated the count as 2 til towards teh end of the month.
So I need to count of all each event_id in place for each day in may.

Hi ALL,
I need help in calculating sum of market value based on property_id. The sum should be calculated by finding the average market value for a given property and then sum the individual average of the property to get the Distinct sum.
I have a very little knowlegde in Cubes and analysis services. I need to perform this distinct sum by using calculated members using MDX on SQL server 2000.
Data example
P_Code Cus Prpty_IdMrkt Val
3000 1234 1111 $10,000 $10,000
3000 1234 2222 $20,000
3000 1234 3333 $30,000 $20,000
3000 5678 1111 $10,000
3000 5678 2222 $20,000 $30,000
3000 5678 3333 $30,000
3000 1020 1111 $10,000
3000 1020 3333 $30,000
Distinct Sum $60,000
Thanks in Advance

I have the following store procedure :
SELECT APHIST.ReturnDate AS ATDATE
,API_HIST.[ActionPlanItemID]
,API_HIST.[ActionPlanID]
,PIT.[ProductItemID]
,PIT.ProductItemCode
,PIT.Name,
[code]....
What I am trying to get is a RunningStock level column which is able to display stock level as describe below :
If ItemStatus value is 0, that means that the item has been taken out from stock.
So based on that the first row running Stock level is calclulated as
(ProductQuantity * ItemUnitWeight)-ItemQuantity=9...
For the second record, ItemsStatus=1 which means the item return to stock, at the time the running stock value calculation should be the previous row Running Stok value (=9 ) +(ItemQuantity*ItemUnitWeight)When the ItemStatus=2, that means the item is definitely out and will be never back to current stock. Is there a way to get that calculation field ?

I am trying to create a "Loan Ledger Card" in SSRS which does the calculation up to report extracting time. I was able to create it on Excel (Click to download the Excel file) as we can calculate amounts for each installment based on Row and Column name. You can test it by putting any amount (Here it should be below 62000 as it is the total balance of loan) in "Amount Paid" yellow cell and see the effect.
I have made a selection in SQL (attached query and result in screenshot). It calculates the total paid amount by now on the first row, and all due amounts in other rows. Basically, It should first deduct the interest from first row, then principle, same process for second row and so on until it covers the whole paid amount.
SELECT
'0' As RN
,memrepay.lnr
,'Repayment' AS Type
,SYSDATETIME() AS NOW
,SUM(memrepay.mprinc) As PrincPaid
,SUM(memrepay.mint) As IntPaid
[Code] .....
How can I do the similar calculation of Excel file in "SQL query" or "SSRS custom code"?

I am on SQL Server 2008 R2. I have a table that contains a field called [Location]. In that field is a UNC path to the physical file on the repository. Is there a way in SQL Server that I can say give me the select sum([Location] UNC file) where criteria? I saw some posts about xp_filesize or xp_GetFileDetails, but I do not see them in master. I am unable to add anything and wondering if there is any native functionality that would allow me to accomplish this!?

I have a table which has name,Speciality,start date and end date. So each person may have 1/more rows .They will have more if they change their specialities. For example if you look at the data below.
AdjusterNameSpecialtyDatestartDateEnd
Test Inside Property2009-08-29 2010-07-31
Test Management2010-08-012012-07-31
If we see at the data above Test has 2 rows because he changed his specialty in the middle.My requirement is to calculate the total number of employees in each month for last 2 years in each speciality. For example if we look at the example above, Test was in Inside property from 2009 Aug to 2010 Aug but if i use just the date start and take the month for each adjuster it gives me the number of adjusters started in that year and month but what i want is Test should be counted in all the months for Inside property until 2010 07 month. Which means i want to have the total number of adjusters present by each speciality for each month of last 2 years .

How to calculate estimated completion time of a job and what is the variance/difference in time based on previous job history. Looking for tsql query which can accomplish this.For example)...Daily a job is taking 10 mins to complete. However, today due to some reason, the job is running over an hour and still running. It could be a blocking issue or some performance issue on the server due to which the job is still running.
In such cases, using a tsql query or a stored proc which monitor these jobs every 3 mins (Configurable value), so every 3 mins , query has to check, if they are any jobs which are taking more time than its usual completion time/avg completion time in that case shoot an email using dbmail functionality i.e. sp_Senddbmail .. From there, DBA can dig further using waits or sql trace etc...

below is what I am trying to achieve:
DateStatesTotal_CompletedCompleted_Difference
08/27/15CA 19,952 0
09/11/15CA 26,336 6,384
10/02/15CA 35,444 9,108
10/08/15CA 38,278 2,834
08/27/15CO27970
09/11/15CO3264467
10/02/15CO42701,006
10/08/15CO429727
below is my code (I almost have what I need) I just can't figure out how show 0 as the completed_difference for the first Date for each state since there is no prior date to calculate against.
MRR_TOTALS_WEEK_OVER_WEEK AS
(
SELECT
T1.[Date]
,T1.States
,T2.Total_Completed
,ROW_NUMBER() OVER(PARTITION BY T1.States ORDER BY T1.States,T1.[Date]) AS ORDERING
FROM TOTAL_CHARTS T1
LEFT JOIN TOTAL_COMPLETED T2 ON T1.[Date] = T2.[Date] AND T1.States = T2.States
)
[code].....

Developing a measure which displays the difference of two values from the selected years.
An example : Show the difference of the sales amount from 2013 and 2015.
Since i am not really into mdx or calculated members.
