I have records that were inserted into a sql server 2005 table using a stored procedure. I now need to remove or delete these records. The only problem is that the table does not contain a relevant column to define in my where clause when using delete command.
Is there any way I can identify these records for deletion.
I have a datagrid control which is bound to a table which containing more than 1000 records. And i want to show only 25 records once a time. I have used paging in datagrid. But each time the next page index is set, query is fired again. This takes lots of time. So what is the easiest way to bound data in this case to improve performance.
I'm trying to remove extraneous characters like quotes, commas, etc from my dataset. I get the fact in the standard way of doing things in your code behind you simply go
string data = data.replace(",",""); or something like this. However, a datasource doesn't seem to give me that capability. What can I do to make it do this? I'm importing data from an excel sheet into a gridview. The commas are goofing up my view. I'd like to replace any commas in the dataset with spaces. Here is the code I have.
I am using oracle as back end. In database there is a table with 5000 records and 160 columns. i want to display all these records in gridview(in asp.net, c#). But it takes more than 10 minutes to fill the dataset.
I have an Access 2010 DB that I have a table of RAW data in. In my scenero when table 'a' has been populated all the rows with the updatedate of Now() get moved to another table... the SQL is like this...
[Code]....
As you can see it is a very simple query but it does NOT return any rows. There are actually 404 rows with todays date in teh Append_Date column.
I am using DataAdapter.FillSchema to create shema of tables in DataSet. I created DataRelation on columns T1id in both tables.
Now when i try to Update Sql Database T1id in Table2 remains 0 and not the value of T1id in Table1.
I can successfully update Sql Database if i fill DataSet with records first (Using DataAdapter.Fill), but that's not what i want to do. I don't need "old" records in my dataset. I want to use dataset just to store all imputs from user until the proccess is done and then insert all those records "at the same time".
I have two tables for storing language translations - tblEN and tblES. They have the same structure which is nvcEnglish and nvcLocal - both nVarChar fields.
In nvcLocal of the Spanish table, I enter the Spanish translations of words and phrases used within my app. Problem is, when I add a bunch of new records to the English table I also have to go in and repeat the data entry into the Spanish table. I am wondering if there is a way to import the newly added records into the Spanish table using Transact SQL?The plain language query would be something like:
If the data in tblEN.nvcEnglish does not exist in tblES.nvcEnglish then insert a new row into tblES with the values from tblEN
I have a situation where i have a dataset with many, many rows but few columns (5). Lets say in one row i have A,B then somewhere else in the dataset i could have another row that has B,A. What i want to do is if A,B exists then remove the row where B,A exists.
I am using dataset which contains some records I want to query with dataset to get every time next 20 records. I don't want to do it throught loop is there any way that I can get next 20 records everytime.
MembershipUser m_user = Membership.GetUser(); DataTable dt = new DataTable(); dt.Columns.Add("SenderUser"); dt.Columns.Add("RcvUser"); dt.Columns.Add("Message"); foreach (ListItem li in lst_Users.Items) {
[Code] ....
I am calling "Application object" from above aspx page into web service page as below:
[WebMethod(EnableSession = true)] [ScriptMethod(ResponseFormat = ResponseFormat.Json)] public string WebMessage() { List<string> list = new List<string>(); DataTable dt = ((DataTable)HttpContext.Current.Application["Message"]);

I have two tables and I want to display the second one based on the primary key:
the first table is tbl1 (id,fName,lName), and the second one is scnds(id,course,tbl1id).
I am practice using MVC 2.0, so I bulilt the the class repository
[Code]....
Then created the Studentcontroller
[Code]....
The problem is if I used Details method it will show only the first record, but I want to display every course that specific a student has. I don't know if the problem in repository or in the controller.
I dont know why my GridView.DataSource is become nothing when the Page.IsPostBack = true.What i did is bind the dataset to the GridView.DataSource when page load. Then when the button click event is trigger i need to get all the records from GridView. But when i debug and check i found that the GridView.DataSource is become nothing. how should i get all records from the GridView and assign to dataset. I'm using VB.net to work on.
Does dataset store all its datatables' records into server memory if I just call one datatable from it?Lets make an example, a dataset with three datatables - tbCompany, tbCompanyStaffs, tbSalesOrderwhere tbCompany is the parent of tbCompanyStaffs. tbSalesOrder is an independant table.Does dataset load all tbCompanyStaffs records into the server memory as well when a class retrive data from tbCompany?
