SQL Server 2012 :: Running Totals With OVER Clause?
May 28, 2015
A while back, a "quirky update" method was proposed for lightning fast running totals based on the three-part MSSQL UPDATE's SET statement and tally tables. However, some claimed this was not 100% absolutely guaranteed behavior.
How does the new OVER clause compare in terms of performance ?
DECLARE @Tbl TABLE
(
pk int not null primary key identity,
N int
)
INSERT INTO @Tbl (N) SELECT TOP 1000 1 FROM syscolumns a CROSS JOIN syscolumns b
SELECT pk, SUM(pk) OVER (ORDER BY pk )
FROM @Tbl
get the desired results for the following sample data set. I was able to come up with a query that returns the the expected results however only for a given day, so I'd need to union several select statements the get the desired results which is definitely not ideal. I'd like to pass a parameter in (number of days) instead of doing a unions for each select.
DECLARE @T TABLE (Id INT, Category VARCHAR(1), [Date] DATE) INSERT INTO @T SELECT 1 AS Id, 'A' AS Category, '2015-5-13' AS ActivationDate UNION ALL SELECT 1, 'A', NULL UNION ALL SELECT 1, 'A', '2015-5-13' UNION ALL SELECT 1, 'A', NULL UNION ALL
I want to create the following scenario. I have a table that stores employees working on projects and their project hours by week, but now I also need a running total per week for each of those projects. For example take a look below:
EmployeeID, Project, Sunday, Monday, Tuesday,....Saturday, ProjectHours, TotalProjectHoursPerWeek(this is the column I am trying to derive), FiscalWeek
Correlated Subquery: SELECT EmployeeID,Project, Sunday, Monday,....Saturday, ProjectHours, SELECT(SUM(ProjectHours) FROM dbo.TableABC ap GROUP BY FiscalWeek), FROM dbo.TableABC a
I got this to work one time before, but now I am getting the following error:
Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.
I have a situation where I want to get running totals of a potentionally very large table. Say I have a million records with a table with few fields. Table structure like this UID value 1 3 2 9 3 4 4 7 5 2
I want to return a result set of something like this select uid, value, (rtotal???) from table
This is to be used for sort of a lotery. Say I have 1 million users with a variety of points tward the lotery. I total the points, is say 5 million, determined the winner to be say 3,234,563 Now I have to determine which uid is the winner. So I planned to to do a running total till the winning value is less then or equal to the running total and I have my winner. I am looking for a fast way to do this on a large database.
I have a problem that I know that i should be able to code up but have drawn a blank due to it being monday. Anyway......
Have a table :
create table test_registrations ( date_maint smalldatetime, user_name1 varchar (255), user_address1 varchar (255), total_users int ) go
If i have a number of registrations on a particular date then I can tell all how many users have registered in any date by :
select date_maint , count (1) from test_registrations group by date_maint order by date_maint desc go
The qestion is how can I keep a total registared users count. Say if I have 10 users join on the 1st of Jan and 15 on the 3rd then I want the total users for the users on 1st to read 10 and total users on the 3rd to read 25.
I know i should be able to code this up but I'm being a dumb ass. Can someone show me a way to code it. Is it some sort of correlated sub query to keep a running total ?
On SQL Server 2005 at least, this works efficiently where we have an indexed row number.
It does seem to be very sensitive to the join condition in the recursive part of the CTE: changing it to the equivalent "ON T.rn - 1 = RT.rn" results in a scan of T each time instead of a seek!
DROP TABLE dbo.T
-- rn must have contiguous values for this to work: CREATE TABLE dbo.T (rn int PRIMARY KEY, f float NOT NULL)
-- 100000 random floats between 0 and 1: INSERT INTO dbo.T SELECT n+1 AS rn, RAND(CAST(NEWID() AS binary(4))) AS f FROM dbo.Numbers GO
;WITH RT AS ( SELECT rn, f AS rt FROM dbo.T WHERE rn = 1
UNION ALL
SELECT T.rn, RT.rt + T.f FROM RT INNER JOIN dbo.T AS T ON T.rn = RT.rn + 1 ) SELECT * INTO dbo.TRT FROM RT --ORDER BY rn OPTION (MAXRECURSION 0)
Now my code below brings everything i want it too, the problems comes is I need to get a running total of sales for each day. Currently it shows the sales for a store for each day and what there projections should be. I need a running total for each day so if you were to have todays date it would have the sum(sales) between today and the first or the month that im in. but still show what the total was on the 10th, 9th, and so on.

I've tried using an if statement (if date = current week, Qty, 0) and then sum the data but I get an error message that reportitems can only be summed in the page header and footer. I've also tried running totals, but it doesn't like the iif statement. Any ideas on how to do this?
I have a table for which I need a “special� running total. More specifically there should be a close communication between the credit and the debit column. The scenario should be in the following order “Credit�“Debit�“Balance credit�“Balance debit� 6 0 6 0 5 0 11 0 0 4 7 0 0 9 0 2 3 0 1 0 0 5 0 4 0 2 0 6
I have to point out that this is done in a grouped form, where the CustormerID is the grouped clause. Now I have achieved this to a point where the calculations work only if the credit column is bigger than 0, but when the account starts with debit I get only sums of the column not the needed subtractions. What am I missing? Thanks in advance.

I want to produce a query that shows on a month/year bases the number of users joined for each month AND show a running total of membership, I'm almost there....just got a problem getting the running totals:
this is what I have so far:
SELECT DATEPART(MONTH, DateJoined) AS Month, DATEPART(YEAR, DateJoined) AS Year, COUNT(UserID) AS NuAccounts FROM Accounts_Users GROUP BY DATEPART(MONTH, DateJoined), DATEPART(YEAR, DateJoined) ORDER BY DATEPART(YEAR, DateJoined), DATEPART(MONTH, DateJoined)
How do I produce a column that shows the running total of accounts?
I have a ms-sql 2012 for this task. I read that running totals / sum over is better supported here.
There are customers with an account where they can insert or withdraw cash. When they insert, the inserted amount will get a date where it expires. After the expiration date, the cash becomes unavailable.
I'm not sure how to design the tables to meet my needs, but this is my best guess. And below is the first problem in the view.
Table: deposit    This table will hold all deposits
customerId    (string) balanceType    (string) transactionDate   (date) expiresOnDate   (date) amount     (decimal) transactionText   (string)
The data set for the deposit table could be:
1 Bonus 01-05-2015 30-04-2016  500  Inserted 500 2 Bonus 01-05-2015 30-04-2016  500  Inserted 500 3 Bonus2 01-01-2015 31-12-2015  100  Inserted 100 2 Bonus2 01-01-2015 31-12-2015  100  Inserted 100
Table: withdrawal  This table will hold all withdrawals
customerId    (string) balanceType    (string) transactionDate   (date) amount     (decimal) transactionText   (string)
The data set for the withdrawal table could be:
2Â Bonus2Â 01-04-2015Â -100Â Â Needed 100 2Â Bonus2Â 02-04-2015Â -100Â Â Needed 100 2Â Bonus2Â 03-01-2015Â -100Â Â Needed 100 3Â Bonus2Â 10-04-2015Â -50Â Â Â Took out 50 3Â Bonus2Â 11-04-2015Â -100Â Â Took out 100
[Code] .....
Now I need to combine the two tables in a view with a running total, ordered by customerId, balanceType and transactionDate
customerId balanceType transactionDate amount Total Text
The view must show this, when selecting all records:
1 Bonus 01-05-2015 500  500  Inserted 500 1 Bonus 01-07-2015 -100 400  Yes, got 100 1 Bonus 02-07-2015 -100 300  Yes, got 100 1 Bonus 03-07-2015 -100 200  Yes, got 100
[Code] ....
And a last view that will show distinct totals for each customer and balanceType
INSERT INTO #t1 (CODE,COLUMN1,COLUMN2) VALUES ('432', 0,100), ('TOTAL FOR 432',0,100), ('4320001',0,250), ('4320001',50,0), ('4320001',0,140), ('4320001',300,0), ('TOTAL FOR 4320001',350,390), ('432002',200,0), ('432002',0,100), ('TOTAL FOR 432002',200,100) drop table #t1
I want to have 4 column (named BALANCE). Balance must be column that represent running totals between two columns (Column1 - Column2) for each group of data. For each group total must start from zero.after total 432 it starts to count again for total 4320001 and again for total 432002. I'm using MS SQL SERVER 2014.
I've created a Report Builder Column chart with months as the x-axis (category) and revenue as the y-axis (value). This correctly displays the revenue for each month, but I'd like to display a running total of the revenue for the year.
I'm currently displaying: Jan $2 Feb $1 Mar $4
I want to display: Jan $2 Feb $3 Mar $7
I know this is possibly using the RunningTotal formula in Reporting Services, but I'd like to do this in Report Builder so the users can change and create their own graphs with running totals. Is there a way to do this in Report Builder?
I have two queries that give me the total sales amount for the current year, and the last year.
SELECT SUM([Sales (LCY)]) FROM [$Cust_ Ledger Entry] cle LEFT OUTER JOIN dw.dim.FiscalDate fd ON fd.CalendarDate = cle.[Posting Date] WHERE [Customer No_] = '10135' AND fd.CalendarYear = '2013'
[Code] ....
I would like to learn how to be able to make this a single query and end up with two columns and their summed up totals. Like it shows on the attached image.
This is my query without the columns I need:
SELECT c.CustomerNumber ,c.Name ,c.ChainName ,c.PaymentTermsCode ,cle.CreditLimit AS 'CreditLimit' ,SUM(cle.Amount) AS 'Amount'
From MS Dynamics NAV 2013 I get a lot of querries that have a where clause like this:
where [Field1] like @p1 and [Field1] < @p2. Field1 is the only primary key field and clustered index. The query also has a TOP 50 clause. @p1 is always a "Starts-With"-value (something like N'abc%').
The query plan uses a clustered index seek but the number of reads look more like a clustered index scan.
Depending on the table size I see 1M or more reads for these querries.
If I rebuild the query in SSMS, but replace the paramerters with actual values I only see a few reads.
I was able to reproduce the issue with a temp table. See code below.
Is there a way to make SQL Server use another strategy when using the parameterized query?
SQL Server Version is 11.0.3401. if object_id('tempdb..#tbl') is not null drop table #tbl; create table #tbl ( [No] nvarchar(20) ,[Description1] nvarchar(250)
Right now I have to do something like this and it is time consuming every time I have to query a specific table...
SELECT lots_of_columns FROM table WHERE (column5 = '1' OR column6 = '1' OR column7 = '1' OR column8 = '1' OR column9 = '1' OR column10 = '1' OR column11 = '1' OR column12 = '1') AND other_query_critiera_here
Typing out the OR statement gets long, time consuming and prone to errors because that first where line with all the ORs can sometimes have 20+ ORs in it. As some insight, the columns are text columns, sometimes they have data, sometimes they are NULL. Sometimes they have the same data (i.e., column5 and column6 and column12 could both have '1' as values).
I would like to be able to combine the functionality of IN and LIKE in a WHERE clause. Although the simple AdventureWorks2012 example below illustrates the concept with 3 search criteria, the real-world example I need to apply the concept to has a couple dozen. This returns 50 rows, but requires multiple OR ... LIKE functions:
SELECT DISTINCT c.Name FROM Sales.Store c WHERE c.Name LIKE '% sports %' OR c.Name LIKE '% exercise %' OR c.Name LIKE '%toy%'
What I would like to do is something like this, which doesn't work:
SELECT DISTINCT c.Name FROM Sales.Store c WHERE c.Name IN(LIKE '% sports %', LIKE '% exercise %', LIKE '%toy%')
I could load up a cursor and loop through it, but the syntax is more cumbersome than the multiple LIKE statements, not to mention most SQL programmers are horrified at the mention of the abominable word 'cursor' for performance reasons.
I am creating a dynamic query where i am appending a where clause something like -
IF (@CurCaptureDate IS NOT NULL) SET @where_clause = @where_clause + CHAR(10) + 'AND CD.CaptureDate = ' + @CurCaptureDate
PS - CD.CaptureDate is datetime and @CurCaptureDate is also datetime
but when executing , it gives this error - Msg 241, Level 16, State 1, Line 169 Conversion failed when converting date and/or time from character string.
i am not able to use convert here with these quotes.
i tried this - SET @where_clause = @where_clause + CHAR(10) + 'AND CD.CaptureDate = ' + CONVERT(VARCHAR(25),@CurCaptureDate )
but it makes it to -
AND CD.CaptureDate = Jul 19 2014 12:00AM. I would need the date in quotes.
Because of the way in which a specific piece of code is written, I'm bound into using a WHERE clause for a report generation.Each Inspection generates a unique Inspection Number. Any re-inspection created from that inspection is assigned that Inspection Number and appended with ".A", ".B", ".C" and so on.
The problem is this: Each row's Primary Key is the "InspectionId" in "dbo.v_InspectionDetailsReports". I need to return not only the data related to that particular InspectionId, but also the data related to any previous related inspection. For example, if I have a main number of CCS-2012 and three re-inspections, CCS-2012.A, CCS-2012.B and CCS-2012.C, and I report on CCS-2012.B, I need all the data for CCS-2012, CCS-2012.A and CCS-2012.B but NOT CCS-2012.C.
I would prefer to not have to do everything in a WHERE statement, but my hands are a bit tied.
The "SELECT * FROM dbo.v_InspectionDetailsReports WHERE . . ." is already hardcoded (don't ask). SELECT * FROM dbo.v_InspectionDetailsReports WHERE ( RefOnly = 0 OR RefOnly IS NULL
I am using an aggregate with the OVER clause.Running the script is fast less than 1 second but when I say insert into a temp table the execution plan is very different at it take 8 seconds.I have attached the execution plans. Also the Statistics IO, Time messages. I am using SQL Server 2014 with backward compatibility to 2008 R2.
if (select OBJECT_ID('tempdb..#MM')) is not null drop table #MM CREATE TABLE #MM ([MyTableID] [int], [ParticipantID] [int], [ConferenceID] [nvarchar](50), [Points] [money], [DateCreated] [datetime], [StartPoints] [money], [EndPoints] [money], [LowPoints] [money], [HighPoints] [money]) insert into #MM ([MyTableID], [ParticipantID], [ConferenceID], [Points], [DateCreated], [StartPoints], [EndPoints], [LowPoints], [HighPoints]) selectmm.MyTableID, mm.ParticipantID, mm.ConferenceID, mm.Points, mm.DateCreated,
I have 10k indexes I need to rebuild and each time the script reaches an error it stops all further activity. How can I append 'GO' to the end of each line so it will continue on error messages?
Once I have the syntax I can do a find and replace function in Notepad++

I have a data table which has list of bills with date and outstanding total.
If the bills dates between 0 and 30 I like to insert the Outstanding total into Colum K , If the bills dates between 31 and 60 I like to insert the Outstanding total into Colum L , If the bills dates between 61 and 90 I like to insert the Outstanding total into Colum M and so on ..
I tried below formula but it is not working
CASE DATEDIFF(day, Ac_Billbook.BillDate, getdate()) Between 0 and 30 THEN Insert into (Ac_Billbook.OutstandingTotal) Value ('K') CASE DATEDIFF(day, Ac_Billbook.BillDate, getdate()) Between 31 and 60 THEN Insert into (Ac_Billbook.OutstandingTotal) Value ('L') CASE DATEDIFF(day, Ac_Billbook.BillDate, getdate()) Between 61 and 90 THEN Insert into (Ac_Billbook.OutstandingTotal) Value ('M')
How I am using a CASE statement within a WHERE clause to filter data:
CREATE PROCEDURE dbo.GetSomeStuff @filter1 varchar(100) = '', @filter2 varchar(100) = '' AS BEGIN SELECT
[Code] .
What I want, is to be able to pass in a single value to filter the table, or if I pass in (at the moment a blank) for no filter to be applied to the table.
Is this a good way to accomplish that, or is there a better way? Also, down the line I'm probably going to want to have multiple filter items for a single filter, what would be the best way to implement that?
the code below works (this is only a quick dumbed down version of the actual code, it might not work 100% for all cases). Is it at all possible to exploit the functions that were added to SSQL since v. 2005 to simplify this code ?
In SSRS, a parameter allows the user to create a list of invoices (from CRM) to be ordered in any of the following ways the user prefers:
'Document Date (most recent date first)' 'Document Number (highest number first)' 'Document Date (most recent first) and Number' 'Document Number (lowest number first)'
The invoices have a (supposedly) sequential identity-generated number. However Accounting may want to set a different date than the creation date on some invoices. So there is no way the invoice numbers will be in the same sequence as the invoice dates.
So I just created the "sorting fields" - they appear as junk in the output dataset (just do not drop them in the SSRS tablix - they have to be part of the SELECT statement to be usable in the ORDER BY clause.
The code is:
DECLARE @ls_OrderBy varchar(80) --'Document Number (highest number first)' --'Customer and Document Date (most recent date first)' --'Customer and Document Number (highest number first)' --'Document Date (most recent first) and Number'
I have a two tables each having a uniqueidentifier column person_id
I am trying to a select statement where I want a list of the person_id's in one table that are not in another table.
-- insert into wch_needed those who need checked
insert into #wch_needed (person_id, rendered_by ) select distinct e.person_id, e.rendered_by from #wch_who o, encounter e where o.person_id not in (select distinct person_id from #wch_have ) and o.person_id = e.person_id
the where conditional
where o.person_id not in (select distinct person_id from #wch_have )
I have some data grouped in a table by a certain criteria, and for each group it is computed a subtotal for the group. Of the values from each of the group, I want to create a grand total on the report by adding every subtotal from each group.
Example: ... .... Group1        Value               10               20 Sub Total 1:     30
Group2         Value                15                25 Sub Total 2:      40
Now, I would like to be able to add subtotal 1 (30) to subtotal 2 (40) and my grand total would be 70. Can I accomplish this task in SSRS?
I'm trying to write a query to select various columns from 3 tables. In the where clause I use a set of conditions, but most important condition is that I only want to see all results from the different columns where the ph.ProdHeaderDossierCode contains at least 25 lines of processed hours. I tried this with group by and having, but I constant get error messages on all other columns that I want to see: "is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause". How can I make this so I can see all information I need?
