DataSource Controls :: Auto-Update Column Whenever Record Is Updated?
Feb 9, 2010
Is there a way I can automatically update a 'Date' column in my database table to the current date whenever any cell in that record is updated?I've started looking into table triggers a little bit and I'm wondering whether I can do it using this?
I am binding repeater control for mega menu, its working fine but i want to repeater do not load every time from database ,it load when any change or add in database ....
I'm trying (poorly I might add) to set up a select statement and due to my noobishness I simply have not found a way to do it RIGHT. Then again - I'm probably starting entirely wrong - but I've gotta' learn somewhere.I'm attempting to track product usage (think mild inventory tracking). In the system, I have independent parts and builds (combination of independent parts) - each has its own SQL table. Each time a "build" is completed, I want to update my part inventory with an updated count of that item.
when I insert any character to column Name then A new string random will auto insert into column Random (picture below) I had used Trigger but It was error !
I want to column Random use to code :
DECLARE @myid uniqueidentifier SET @myid = NEWID() insert into table_1 values(@myid, substring(CONVERT(varchar(255), @myid), 1, 5))
but It must auto like column Number (column Number is Identity)
I have an orders table with a column names orderID. What I want to do is insert a new record and get the value from the new orderID column. The orderID is my Primary key. The Insert SQL I have now is -
INSERT INTO orders (creditAutorizarionNumber, OrderName, OrderPersonPhone, OrderPersonEmail) VALUES (@creditAutorizarionNumber,@OrderName,@OrderPersonPhone,@OrderPersonEmail)
How do I write the query to get the newly entered orderID ?
I am not sure if I am in the right spot here because this really doesn't have to do any datacontrol but hopefully somone can give me a hand with this.
Basically I have a bunch of TextBox controls on a page that are displaying the data I want but when I try to run an UPDATE query on the record I get nothing. The record values don't update and I don't appear to get any exceptions.....I am actually kinda really baffled on this one, here is what I have for the update code: [Code]....
Btw, if there is an easier way to do this with a control I am up for suggestions as I am just going off of some of my old VB6 ways
I am in a serious trouble right now, i wanted to know that how to write a query in LINQ to SQL to retrieve identity column's current value before inserting any value.
I need this cos i m building a windows app n i need to display this value before inserting a record. I have tried DataContext.ExecuteCommand('DBCC CHECKIDENT (Tablename)') but it returns the number of rows modified.
I'm currently working on a small project and therefore created a gridview, including one bit column which has been linked with a checkbox in both the itemtemplate as the edititemtemplate (autopostback = true).Databinding for these two checkboxes has been linked (two-way) to the bit column.Now I want to display the gridview to end-users. They should be able to just click on the checkbox so they value in the database column gets changed as well (as I want to run update queries behind it), but not passing via the command column 'EDIT'.=> problem I'm having now is that the bit column in the database doesn't get updated.
my requirement is to update a duplicate record in datatable.in my website if anyone select a product more than one time then i have to check and update the quantity of that record.i use for loop for this but it is not working properly, it is running perfectly for one product but when i add another product it won't work.how can i do this?Here is my code part which is run on add button click
if (sc.dtcart.Rows.Count > 0) { for(int i=0;i<sc.dtcart.Rows.Count;i++)
I have been able to successfully read a row of data from an SQL table using two column parameters. Now I would like to update this row with new information. Is this possible since the reader does not specify which row was read with the 'reader.Read();' command?
After this and in the same procedure i want to update the inserted or the updated record which occared in the above code with the follwing update statment :
[Code]....
updating mark is completed successfully if the record is existed (Update Case) but if the record does not exist (new record) ... the update of the mark is not occured ..
want to know if linq to sql auto updated the id column of a class (table row object) after SubmitChanges is called inserting a new row to that table, that would be fantastic, would anyone be able to confirm this?
I am creating a database frontend in aspx/C# using LINQ to MSSQL. It has two pages: a main page which lists all of the records, and a page that appears when the user click the "Edit" button next to one of the list items for the user to edit a record.The database table has about 70 user-editable fields. I need to make the edit page, allowing the user to update/insert records. There are a couple ways I can think of make an edit page:Using a LinqDataSource and FormViewUsing a LinqDataSource and DetailsViewManually retrieve the value for each field and set the value for each field directly from Linq (e.g. "projectIDLabel.Text = Convert.ToString(thisRecord.Project_ID)"What would be the best way to design this?
This is SQL Server 2008 database. I have a tables which has a XML datatype column, Is XML Document = true, and ScemaCollection = InternalAttributeCollection.This is my schema
[Code]....
This is my table
[Code]....

[Code]....
Now, the xml column is nullable and is currently is null for the John Doe record. I tried this update:
[Code]....
I get this error: "XML Validation: Declaration not found for element 'InternalAttributes'. Location: /*:InternalAttributes[1]"
when i want insert a record i see an error like this Can't perform Create, Update, or Delete operations on 'Table(MainMenuLink)' because it has no primary key. with this codes:
MyLinqDataClassesDataContext db = new MyLinqDataClassesDataContext(); MainMenuLink li = new MainMenuLink { Link = "www.tprogrammer.com", LinkSubject = "subject" }; db.MainMenuLinks.InsertOnSubmit(li); [code]....
I have a gridview which has a column of auto generated select buttons, where a user can select a row.However, I would like to add a column header to my auto generated select buttons in order to make the gridview look complete, but I am unable to see how I can do this. Does anyone know how I can add a header text to an auto generated select button?
On one (aspx) page I have a GridView (GridView has multiple pages). After a user selects a row/record and clicks "edit" he's redirected to another (.aspx) page where he edits the selected record via DetailsView. fter clicking update on DetailsView he's redirected back to the page containing the GridView.What is the simplest/shortest way that the updated record is automatically selected on the Gridview (e.g. at Page_Load event)?
There is a very common problem I am facing in my new webproject in gridview control.The sequence of the execution of the process is as follows:There are some search parameters in SearchPage with a gridview. In gridview's rows there is an Edit button.By providing search parameter(s), data populated to gridview and if we click edit button a new page opens as a popup to update record.In new page the record is updated fine. On successful updation user close the window but he goes to the Search page he again finds the same record with the same parameters to see changes it remains unchanged.Its only changed when he search another record and then again provides the previous parameters.I don't know why is this behaviour of gridview?
I am developing membership for website. SQL Server 2005 is at backend. I want Column <Package> to "Free" from "Premium" automatically when month ends. The website is membership per month basis. Two type of members "Free" and "Premium".
