Hello,
I am very new to SQL and just getting to learn this stuff. To make this question easier I will scale down the fields dramatically.
I have about 8000 records close to 2000 records for the last 4 years
and I would like to create a query that will create a table on my SQL server. I need to bind the data based on two items the Year and the Name and average several records. However, one record needs it's own calculation.
Here are my field names:
[year] ***4 choices 2007, 2006, 2005, 2004***
[name]
[rush_no] ***integer***
[rush_net] ***integer***
[YPC] *** This field needs to be calculated by [rush_net] divided by [rush_no]***decimal***
I also need to create the same table that will "total/sum" the same records.
Hi,I am trying to add a staggered running total and average to a queryreturning quarterly CPI data. I need to add 4 quarterly data pointstogether to calculate a moving 12-month sum (YrCPI), and then tocomplicate things, calculate a moving average of the 12-month figure(AvgYrCPI).Given the sample data:CREATE TABLE [dbo].[QtrInflation] ([Qtr] [smalldatetime] NOT NULL ,[CPI] [decimal](8, 4) NOT NULL) ON [PRIMARY]GOINSERT INTO QtrInflation (Qtr, CPI)SELECT '1960-03-01', 0.7500 UNIONSELECT '1960-06-01', 1.4800 UNIONSELECT '1960-09-01', 1.4600 UNIONSELECT '1960-12-01', 0.7200 UNIONSELECT '1961-03-01', 0.7100 UNIONSELECT '1961-06-01', 0.7100 UNIONSELECT '1961-09-01',-0.7000 UNIONSELECT '1961-12-01', 0.0000 UNIONSELECT '1962-03-01', 0.0000 UNIONSELECT '1962-06-01', 0.0000 UNIONSELECT '1962-09-01', 0.0000 UNIONSELECT '1962-12-01', 0.0000 UNIONSELECT '1963-03-01', 0.0000 UNIONSELECT '1963-06-01', 0.0000 UNIONSELECT '1963-09-01', 0.7100 UNIONSELECT '1963-12-01', 0.0000 UNIONSELECT '1964-03-01', 0.7000 UNIONSELECT '1964-06-01', 0.7000 UNIONSELECT '1964-09-01', 1.3900 UNIONSELECT '1964-12-01', 0.6800 UNIONSELECT '1965-03-01', 0.6800 UNIONSELECT '1965-06-01', 1.3500 UNIONSELECT '1965-09-01', 0.6700 UNIONSELECT '1965-12-01', 1.3200I am trying to return the following results:Qtr CPI YrCPI AvgYrCPI-------- ----- ----- --------1-Jun-60 1.481-Sep-60 1.461-Dec-60 0.721-Mar-61 0.71 4.371-Jun-61 0.71 3.601-Sep-61 -0.70 1.441-Dec-61 0.00 0.72 2.531-Mar-62 0.00 0.01 1.441-Jun-62 0.00 -0.70 0.371-Sep-62 0.00 0.00 0.011-Dec-62 0.00 0.00 -0.171-Mar-63 0.00 0.00 -0.181-Jun-63 0.00 0.00 0.001-Sep-63 0.71 0.71 0.181-Dec-63 0.00 0.71 0.361-Mar-64 0.70 1.41 0.711-Jun-64 0.70 2.11 1.241-Sep-64 1.39 2.79 1.761-Dec-64 0.68 3.47 2.451-Mar-65 0.68 3.45 2.961-Jun-65 1.35 4.10 3.451-Sep-65 0.67 3.38 3.601-Dec-65 1.32 4.02 3.74Note, 4 data points are required to calculate a moving sum of CPI(YrCPI) and 4 calculate YrCPI figures are required calculate theannual average of YrCPI (AvgYrCPI), giving a staggered effect to thefirst 7 resultsThis sad effort is about as far as I've got:SELECT I.Qtr, I.CPI, SUM(S.CPI) AS YrCPIFROM QtrInflation IJOIN (SELECT TOP 4 Qtr, CPIFROM QtrInflation) SON S.Qtr <= I.QtrGROUP BY I.Qtr, I.CPIORDER BY I.Qtr ASCCan anyone suggest how do achieve this result without having to resortto cursors?Thanks,Stephen
I am trying to build various reports that compares data over time. I have one that measures Year Over Year % difference for number of incoming projects. I managed to do that easily by calculating the following
Where Projects is the metric in question, TrendData is the table that contains project data and CalendateDate is the Date Table. But now I am trying to compare the same YTD projects data to number of projects that came in the last 6 months. How do our projects compare to average number of projects that came in last 6 month period.
I tried the the DATEADD function instead but got no luck and data came out wrong!
Does anyone know how I can determine the number of page writes that have been performed during a set period of time? I need to figure out the data churn in that time period.
Procedure Intermediate New Old Total avg Proc1 6 0 0 6 2.000000 Proc2 74 13 0 87 29.000000 Proc3 29 0 0 29 9.666666 Proc4 16 0 0 16 5.333333
And I want to dynamically calculate the average rather than divide the total by the number of columns every time, I want to divide only by the number of non zero values per row for intermediate, new and old. So row 1 average would just be itself = 6, row 2 would be 74+13+87/3 etc.
;with cte as ( select f.Procedure, SUM(case when f.old_new = 'O' then f.Value else 0 end) "Intermediate", SUM(case when f.old_new = 'Y' then f.Value else 0 end) "New", SUM(case when f.old_new = 'N' then f.Value else 0 end) "Old"
Select AVG(AVG_Back), AVG(AVG_Yield) FROM tblUser WHERE Date Between '3/1/2008' AND '3/31/2008'
I want to limit the AVG_Back field to exclude all values of 0. So only average AVG_Back if the value > 0. What is the best way to accomplish this? I can't just put it in the where clause or the AVG_Yield will be excluded too.
I have a text file which needs to be created into a table (let's call it DataFile table). For now I'm just doing the manual DTS to import the txt into SQL server to create the table, which works. But here's my problem....
I need to extract data from DataFile table, here's my query:
select * from dbo.DataFile where DF_SC_Case_Nbr not like '0000%';
Then I need to create a new table for the extracted data, let's call it ExtractedDataFile. But I don't know how to create a new table and insert the data I selected above into the new one.
Also, can the extraction and the creation of new table be done in just one stored procedure? or is there any other way of doing all this (including the importation of the text file)?
how to solve this problem .... I want to select te sum of nvarchar column and this error always happen
what is the solution this is my query
"SELECT Datein AS Date,SUM(Durm) AS DurationMin, COUNT (*) AS 'Number of Hits' FROM Rayyan_Log WHERE (DNIS = '"+DropDownList1.SelectedItem.Text +"') AND (Datein between '"+TextBox2.Text+"' and '"+TextBox3.Text+"') GROUP BY Datein ORDER BY Datein"
I haven't a clue how to accomplish this.All the data is in one table. The data is stored by registration dateand includes county and number of students brokne out by grade.Any help appreciated!Rob
EX: I have a table for products, and each product has a quantity. How can I add up the QTY field in all the rows to find out the total QTY of all the products.Any help would be greatly appreciated.gkc
I am using SQL Server 2012, and I have a query that gets data from 4 different sources and sums them all up into one field to get a total, and right now I am using 4 queries for each data source and using UNION ALLs to combine them and I was wondering if there is a different way to accomplish this without using UNION statements.Here is a sample of my code.
SELECT Resv01 = ISNULL(SUM(Resv01),0) FROM ( SELECT Resv01 = SUM(Reservations)
i want to create a data mart from an existing OLTP database. for example northwind or i will create an OLTP database. i dont know how i can create data mart from OLTP database. i want to learn that step by step. help me??? please!!
I would like to know the total length of data type in a table. I ran the following query. Will this give me the correct information? I also ran sp_columns <table name> and it too give the length. But There is a difference in the numbers. Am I doing something wrong and which is the correct the query or sp_column.
select sum(length) from syscolumns where id in (select id from sysobjects where name = 'XYZABC')
i have one col in a nonclusted index which is bigint 8 bytes follwoing result shows min_record_size_in_bytes and max_record_size_in_bytes is 20 that is 12+8 page size is 8 kB. does that mean a record will use 20 bytes in a page or it will only use the space equalent to data stored in the col.what i have seen is page count is same weather i put some data in the col or null
I am counting order type by a field which can have 3 different values.In a stacked column chart I am displaying the count of those different values, and showing a data label with the count for each order type. See screenshot.
Now I would like to show a line based on the total of each order type. I can see that SSRS already know the number of each order type as it is shown in the labels.
How do I add those numbers (shown in the labels) together and get it into a Total field? I would prefer not to alter my SQL query, if possible.
I trying to get the moving total (juts as moving average). It always sum up the current record plus previous two records as well and grouped by EmpId.For example, attaching a image of excel calculation.
I have the membership stuff up and running. I've added a field to the membership table called custnmbr. Once a user logs in, I want store his custnbmr in the session and use that to lookup data in another db. ie: Joe logs in and his custnumbr is 001, he goes to the login success page and sees his list of service calls which is: select top 10 * from svc00200 where custnmbr = 001 (the membership.custnmbr for the logged in user) I know how to do this in old ASP using session variables....but I have no idea where to even start with .Net. Many thanks
I am wondering if it is possible to use SSIS to sample data set to training set and test set directly to my data mining models without saving them somewhere as occupying too much space? Really need guidance for that.
Hi,First post so apologies if this sounds a bit confusing!!I'm trying to run the following update. On a weekly basis i want toinsert all the active users ids from a users table into a timesheetstable along with the last day of the week and a submitted flag set to0. I plan then on creating a schduled job so the script runs weekly.The 3 queries i plan to use are below.Insert statement:INSERT INTO TBL_TIMESHEETS (TBL_TIMESHEETS.USER_ID,TBL_TIMESHEETS.WEEK_ENDING, TBL_TIMESHEETS.IS_SUBMITTED)VALUES ('user ids', 'week end date', '0')Get User Ids:SELECT TBL_USERS.USER_ID from TBL_USERS where TBL_USERS.IS_ACTIVE = '1'Get last date of the weekSELECT DATEADD(wk, DATEDIFF(wk,0,getdate()), 6)I'm having trouble combing them as i'm pretty new to this. Is the bestapproach to use a cursor?If you need anymore info let me know. Thanks in advance.
I have a view that give me the data of all the batched. Now I am using a query on view to get a single batched data. when I am using direct query it was taking 0 sec but when I am using Through view "select * from myView where batched=2" then its taking 30 mnt.
i someone had teach me how to write a query in datatable. however i need to get the data out from my database rather than the data table. can someone teach me how should i do it?esp at the first like.... like DataTable dt = GetFilledTable() since i already have set of data in my preset table i should be getting data from SqlDataSource1 right ( however i am writing this in my background code or within <script></script> so can anyone help me? protected void lnkRadius_Click(object sender, EventArgs e) { DataTable dt = GetFilledTable(); double radius = Convert.ToDouble(txtRadius.Text); decimal checkX = (decimal)dt.Rows[0]["Latitude"]; decimal checkY = (decimal)dt.Rows[0]["Longitude"]; // expect dt[0] to pass - as this is our check point // We use for rather than fopreach because the later does not allow DELETE during loop execution for(int index=0; index < dt.Rows.Count; index++) { DataRow dr = dt.Rows[index]; decimal testX = (decimal)dr["Latitude"]; decimal testY = (decimal)dr["Longitude"]; double testXzeroed = Convert.ToDouble(testX -= checkX); double testYzeroed = Convert.ToDouble(testY -= checkY); double distance = Math.Sqrt((testXzeroed * testXzeroed) + (testYzeroed * testYzeroed)); // mark for delete (not allowed in a foreach - so we use "for") if (distance > radius) dr.Delete(); } // accept deletes dt.AcceptChanges(); GridView1.DataSource = dt.DefaultView; GridView1.DataBind(); }
I am working on a school project and have come up against a bit of a sticking point. I am supposed to be creating a very basic OMS, the teacher themselves have said they do not know how to do this (in previous years it has all be done via Access) but apparently I am a lucky one to be doing it in SQL this year.
One of the user requirements of the OMS is to fill a data grid with product name and the product details which I have the query for or rather I have created a view for, which is then queried from a stored procedure.
CREATE VIEW [dbo].[v_stock] AS SELECT tab_products.productname, tab_productdetails.description, tab_productdetails.image, tab_productdetails.price, tab_productdetails.stock FROM tab_productdetails INNER JOIN tab_products ON tab_productdetails.productid = tab_products.productid
The problem I am having is then returning the data from this query into a data grid, I think the reason is because when I attached the stored procedure to a table and then call that procedure via the table adapter there is a mismatch of the schema - specifically the table it is attached to does not contain the column "productName".
I am thinking I need to create a temporary table to fill the data grid with - however, I am not sure how I would create a temporary table.
Is there something I am missing or not done correctly. As far as I can tell the queries work as when I preview them they produce the expected results.
Calculation of an average using DAX' AVERAGE and AVERAGEX.This is the manual calculation in DW, using SQL.In the tabular project (we're i've noticed that these 4 %'s are in itself strange), in a 1st moment i've noticed that i would have to divide by 100 to get the same values as in the DW, so i've used AVERAGEX:
The results were, respectively: 701,68; 2120,60...; -669,441; and finally **-694,74** for Avg_FMPdollar.i can't understand the difference to SQL calculation, since calculations are similar to the other ones. After that i've tried:
test:=SUM([_FMPdollar])/countrows('Fct Sales') AND the value was EQUAL to SQL: -672,17 test2:=AVERAGE('Fct Sales'[_Frontend Margin Percent ACY]), and here, without dividing by 100 in the end, -696,74...
So, AVERAGE and AVERAGEX have a diferent behaviour from the SUM divided by COUNTROWS, and even more strange, test2 doesn't need the division by 100 to be similar to AVERAGEX result.
I even calculated the number of blanks and number of zeros on each column, could it be a difference on the denominator (so, a division by a diferente number of rows), but they are equal on each row.
It seems to be subtracting the value of field3 from the total of 3 fields at some points instead of giving me the average.Some of the results are here:
Count Field1 Field2 Field3 Total Average ===== ====== ====== ====== ===== ======= 2NULL6NULL66 11NULL28134129 10NULL33NULL3333 3NULL12NULL1212
i have 3 tables, each with a date(it has daily dates) column(column name is same in all tables) Each table has columns say "value1","value2", "value3"
i want data from all these tables together.such that my first column will have data weeks and other 3 columns count1,count2,count3 will have average of next 4 weeks count..placed infront of week.
I have created a table in a database for a football that I want to update as the season progresses. Is there any way I can add the new data to the old data in my columns through SQL rather than searching for the old data, doing the maths in my head and doing a simple update query? I know it doesn't save much extra time but I can get awful lazy when it comes to extra maths!
Example would be:
Player Minutes Adam 287
Adam has played 287 minutes prior to the most recent match in which he played 67 more. I would like to know if its possible to do an update where I can just simply add 67 onto the existing numbers with one query rather than find Adam's minutes, use a calculator, do a table update.
hi everybody, i want to create data source and data source view for data mining, with using C Sharp. i have create data source and data source view and export to XML file, but when i change to another computer, run those XML file, it return error, when i run statement to create and biuld mining model, what can i change on xml or how to run XML on another computer sucessfully, and have i build data source and data source view, how to do it.?
Today I was making a few reports. When I tested the reports in Visual Studio, they worked great: I got the expected result. But when I deployed the reports to our reportserver the problem started. When I click on the directory in which my reports are deployed, I got my 4 reports. Till now everything worked correct. But when I click on a report to view the results it went wrong. I got an error: "Cannot create a connection to data source 'Live'" (Live is the name of our data source).
We are using the Windows Logons and I am sure that I have all the rights on the server, I gave myself 'sysadmin' rights, so it should work. I also have tried it with all the roles assigned on my account, but then it still won't work.
When I modify the data source, and set it to another server en database it works. The datasource 'Live' exists on a x64 MsSQL server, en the other datasource is on a x86 MsSQL server. Maybe that is the problem?
