DataSource Controls :: Sql Retrieve All Upper Rows From A Starting Row?
Mar 17, 2010
I would like to retrieve all upper rows from a starting row.
First you need do know the structure :
tb_Actions: actionId, prevActionId, nextActionId
If I have 3 actions in the table and that I pass the actionId to a query I would like to reveice all prev actions from the given action.
row a: 1,null,2
row b: 2,1,3
row c: 3,2,null
actionId 3 will return row b and row a, while actionId 2 will return only row a.
how to perform this with SQL ? I could also do a query for each element in C#, but thats maybe overkill to access each time the database if I can do it in one shot.

I am trying to retrieve the number of rows from a stored procedure. I was trying to use @rowCount as an output parameter in my stored procedure but every time I use that SqlDataSource1 won't retrive me any data. Once I removed @rowCount from my SP I get all the data but don't know how to retrieve the Total number of rows :(
I was trying to do this:
protected
void SqlDataSource1_Selected(object sender,
SqlDataSourceStatusEventArgs e)
{
// lblTotalRows.Text = (string)e.Command.Parameters["@rowCount"].Value;
}

I have a dataset where I would like to upper all string fileds and when done check each field for a value. The other way i thought to do it is to do an upper of each string when I do the conditional check. I would like to know what is quicker upper of the values in the dataset or upper in the conditional statement? Knowing the dataset will contain a max of 10.000 rows and there are multiple conditional statements in the complete process.

I have one big DataTable with X rows. I want to select Y rows from it and bind them to a new ViewList. While doing it, I want to delete these rows from the DataTable (Having X - Y rows).
What is the best and fast way to do it?
I don't know if it is better to create a new DataTable to have the Y and after that bind them to a ViewList or something else?
I'm also looking for example in code how to select/delete rows from DataTable.

I have table called "Logs". It has username, sitename, actiondate and lastupdate columns.
From this, I hve created tempLogs (Temp table) using condition where lastupdate >= somedate.
Once I get records in my temp table, I then want to retreive all the records again from "logs" table corresponding to same
username, sitename?
How would I do that.
BTW: Join will not work.

When I attempt to store the current time of 'DateTime.Now' in a column defined as time in a table within an SQL database, I get an error message that says: Cannot implicitly convert type 'System.DateTime' to 'System.Timespan'.
I have no trouble storing the current date of 'DateTime.Today' in a column defined as date, but this column will not also store time along with the date. The date column has properties that indicate it has a data and system type of date with a Length of 3 and a Numeric Precision of 10. The time column has properties that indicate it has a data and system type of time with a Length of 5, a Numeric Precision of 16 and a scale of 7. Did I define the time column incorrectly for storing the time of day?

I want to retreive some data from an SqlDataSource using it's Selected event I've tried
DataView dv = (DataView)SqlDataSource1.Select(DataSourceSelectArguments.Empty)
but here it's going into in infinite loop and then it gives me an StackOverflowException error in ASP.Net Development Server (my dev machine) and if I publish to IIS it requires me an user name and password to connect to server and gives an InternetExplorer error "Sys.WebForms.PageRequestManagerServerErrorException. An unknown error ... status code returned was 400. The SqlDataSource is in an UpdatePanel. Maybe this is why I get this.

I have been searching on here for many hours and read many posts but for some reason I am being slow and cannot figure this out. I am writing a record and need to get the identity field back. I have tried many combinations based on what I have read but the below code is where I am sitting at now. it has appdatasource.ExecuteScalar() underlined and the error says 'ExecuteScalar' is not a member of 'System.Web.UI.WebControls.SQLDataSource'. I would be very grateful if someone could point out what I am missing to get this to work.
Protected Sub SubmitApp_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles SubmitApp.Click
Dim appdatasource As New SqlDataSource
appdatasource.ConnectionString = ConfigurationManager.ConnectionStrings("ConnectionString1").ToString
appdatasource.InsertCommandType = SqlDataSourceCommandType.Text
appdatasource.InsertCommand = "INSERT INTO APPLICATION (FirstName,MiddleName,LastName,AcceptTerms,IPv4Address,DateInserted) VALUES (@FirstName,@MiddleName,@LastName,@IPv4Address,@DateInserted);select @@SCOPE_IDENTITY"
appdatasource.InsertParameters.Add("FirstName", fname.Text)
appdatasource.InsertParameters.Add("MiddleName", minit.Text)
appdatasource.InsertParameters.Add("LastName", lname.Text)
appdatasource.InsertParameters.Add("DateInserted", DateTime.Now())
appdatasource.InsertParameters.Add("IPv4Address", Request.UserHostAddress.ToString)
Dim appid As Integer = appdatasource.ExecuteScalar()

I have an app that connects to only one db for all of the data that the app has access to. My connection string is in the Web.Config file. In each of my DAL classes I have the following code that gets the connection string from the Config file. This works with no issues but I thought there might be a better way of doing this that I don't know.
If I wanted to change the name of the connection string that any of the DAL classes would use then I would have to change the name of the connection string in each of the files. I thought about creating a new class that would hold this then I could just instantiate a new instance of the class to access this with each of the DAL classes that needs access to it. Then if I needed to change the name of the connection string then it would only be in one place. I suspect there is an even better way of doing this that i don't know about.
