Increment Download Count Select And Update Together.
Mar 25, 2006
Hi is there away of doing both my select and update of a field in my database (m not using store procedures)
Basically all I need to do is get the value of DownloadTimes then add 1 and re update it.
Also to stop missing increments what the best way to lock the database while an update is in progress?
This is basically firing after a user clicks a file to download. I bring up the dialogue for them to save it is it possible to get which button they press and what is the best way to deliver it to them eg response.writeFile()??
Does anyone know if SQL has a built in function for returning increments of rows. For instance; I have a table with 100,000 rows, but would like to return 512 rows at a time. I've looked at the documentation and haven't came across anything that will do this. Any help is appreciated.
Startdate, rec_num , recursive_value, recursive_date 04/02/2014 3 d 04/02/2014 04/02/2014 3 d 04/02/2014 04/02/2014 3 d 04/02/2014
I will like to update recursive_date to emulate the recursive_number and recursive_value fields which specify every 3 days. The recursive_value field can also be w to specify weeks, m to specify month or y to specify years. So my value in the recursive_date field should be updated as followed
Startdate, rec_number , recursive_value, recursive_date 04/02/2014 3 d 04/02/2014 04/02/2014 3 d 04/05/2014 04/02/2014 3 d 04/08/2014
Following is a query which gives me an output as mentioned below. Can anybody help me out, in giving increment numbers, e.g. 1,2,3,4... to the first column in the select statement.
use account select 'PT','JE01','71','1','1', Vou_date=convert(varchar,vdt,101), cltcode, '994801', vamt, 'ZJE01','JOURNL', '0.00', narration, DrCr = (case when drcr = 'D' then 'D' else 'C' end), '','','71','1','P',',',',',',' from ledger where cltcode = '5555' and vdt >= 'Apr 1 2007' and vtyp = '15' order by vdt
How I can get the following Desired SELECT STATEMENT with the increment of Max(serial_no)+1. Date will be in quotation in desired SELECT STATEMENT. All data is same. Just changing the serial_no which will be Max(serial_no)+1.
Create table #seq (serial_no numeric, Scode numeric, Sdate datetime, SErr char(10)) insert into #seq values (1,1002,'10/10/2015','SEDT') insert into #seq values (2,1005,'12/10/2015','PEFT') insert into #seq values (3,1004,'1/1/2015','QEGT') insert into #seq values (4,1008,'1/2/2015','TEWT') insert into #seq values (5,1007,'3/10/2015','REDT')
Hi guys,I followed the ASP.net official tutorial to create a DAL & Business Logic Layer (http://www.asp.net/learn/dataaccess/tutorial02cs.aspx). I have a table with a int ID field. I wish to write a function to add a new entry into this table but have the ID field auto-increment.The ID field is set as the Identity Column and has a Identity Increment & Seed of "1". If I manually go to the table and insert a new record leaving the ID value null it automatically increments. But if I create a C# function to add a new entry I get an error saying that the ID field can't be Null. Is there any way to use the Update method as shown on line 14 below to add a new entry but with it automatically incrementing? I did create a function called InsertDevice that simply inserts the other fields using a SQL INSERT and it auto-increments fine, just wondering if there is a way to do it using the DataTable and the Update method? Thanks for any help!!! 1 public bool AddDevice(string make, string model) 2 { 3 //cannot have the same device entered twice! 4 if (Adapter.FillDeviceCountByMakeModel(make, model) == 1) 5 return false; 6 7 RepositoryDataSet.DevicesDataTable devices = new RepositoryDataSet.DevicesDataTable(); 8 RepositoryDataSet.DevicesRow device = devices.NewDevicesRow(); 9 10 device.make = make; 11 device.model = model; 12 13 devices.AddDevicesRow(device); << Error thrown Here! 14 int rows_affected = Adapter.Update(devices); 15 16 return rows_affected == 1; 17 }
Due to localization I have the need to make child tables, where there is a composite Primary Key, between the Id column and the LanguageSign column. On the parent table the Id column is Identity column with auto increment.
The problem is that during the select into query to copy columns from parent to child, this auto increment behaviour of the parent-Id is copied to the child-Id. However I do not want that, because the same Id will be used by different LanguageSign entries
Is there a way to use 'select into' without copying the auto increment, or is my only option to make a whole new column without auto increment on the child and copy the records?
btw I have used this statement
SET IDENTITY_INSERT MyTable
ON , so that inserting into the Id column is possible. I can see however that this does not take away the auto increment...
I Have a table that needs to have 2 unique number.
detail_id and detail_print_id.
detail_id is already an IDENTITY.
both fields need to be different, because when importing, it imports the same data into a table twice, with only a slight data change (and id is not one of the changes).
So I thought i could do the following:
detail_id INT NOT NULL IDENTITY(1,2), detail_print_id INT NOT NULL IDENTITY(2,2), --blah blah
that way, the detail_id will always be odd, and the detail_print_id will always be even. however SQL Server 2005 only allows 1 identity per table, and both these fields need to be auto generated when the field is inserted, so as to prevent double data.
is there anyway I can create a int column to auto increment, without the column being an IDENTITY??
also, I would prefer to not have to create a second table with a single column just for this work.
Select COUNT(DATEDIFF(d, DateintoSD, SDCompleted) - DATEDIFF(ww, DateintoSD, SDCompleted) * 2) AS 'Total Jobs Completed' From Project WHERE (SDCompleted > @SDCompleted) AND (SDCompleted < @SDCompleted2) AND (BusinessSector = 34) AND (req_type = 'DBB request ')
I am using three tables in this query, one is events_detail, one is events_summary, the third if gifts. The original select statement counted the number of ids (event_details.id_number) that appear per event_name (event_summary.event_name).
Now, I would like to add in another column that counts the number of IDs that gave a gift who attended an event that were also listed in the event_ details table. So far I have come up with the following. My main issue is linking the subquery properly back to the main query. how to count in the sub-query and have the result placed within the groups results in the main query.
SELECT es.event_name, es.event_id, COUNT(ed.id_number) Number_Attendees, ( SELECT COUNT(gifts.donor_id) AS Count2 FROM gifts WHERE gifts.donor_id = ed.id_number ) subquery2
Hi Guys, I cannot seem to get the syntax right on this one. I am trying to Update a field in a table with the recount of another table. Is it even possible to do this???
Update P_Dates SET RecCount = RecCnt FROM (SELECT Count(ACCTNO) As RecCnt FROM IMPORT Where @sDate = StartDate AND @eDate = EndDate)
I am trying to update a field in a temptable with the count of items in another table. To illustrate, CustomerID=23 and I want the number of occurences in the temp table. Here's the code which DOESN'T work:
INSERT INTO TempTable ( CustomerID, FirstName, LastName, DateAdded, AlbumPicture, LayoutCount ) SELECT Albums.CustomerID, Customers.FirstName, Customers.LastName, DateAdded, AlbumPicture, COUNT(*) FROM Layouts WHERE Layout.customerID = Albums.CustomerID FROM Albums JOIN Customers on (Albums.CustomerID=Customers.CustomerID)
Please take a look at the COUNT line. Here I want to count the occurences of a specific customerid in another table and put in into th LayoutCount field.
SQL server reports "Incorrect syntax near the keyword 'FROM'". Any ideas how to achieve this?

I am having trouble creating a query which will list schools with ALL their Admission = Null. For example, if at least one record is not null, don't list it, but as long as ALL the records have Admission = Null, then list it. I hope that's clear. Thanks!

Hello,We have a database filled with local restaurants for a directory. What I'm trying to do is display a list of all the cuisines and the number of restaurants who serve that type of cuisine in parentheses. It should look like the example below:American (12)Chinese (3)Italian (5)...Here are the tables with only the relevant columns: restaurants---------------...cuisine_id... cuisines-----------cuisine_idcuisine_name... So basically I want to pull all the names from the cuisines table and then the restaurant count from the restaurants table. The only way I can think of doing that is to grab the cuisine_ids, put them in an array and then use that in a loop to get the count from the restaurants table. That's not very elegant. Is there a better way?Thank you
