I have a client/server app. that uses a windows service for the server and asp.net web pages for the client side. My server class has 3 methods that Fill, Add a new record and Update a record. The Fill and Add routines work as expected but unfortunately the update request falls at the 1st hurdle.
I pass two params to the remote(server) method for the update, one is the unique ID and the other is a string that is the name of the table in the database. See code below. I need the SelectedRow method to return a datarow that will then populate textbox's on another page. When the method is called I get an 'internal system error.....please turn on custom errors in the web.config file on the server for more info.(unfortunately my server is not s web server so I don't have a web.config file!!).
Can anyone see anything obvious.
Cheers. >>
Calling routine:
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
System.Threading.Thread.CurrentThread.CurrentCultu re = New CultureInfo("en-GB")
Public Function SelectedRow(ByVal id As Integer, ByVal discipline As String) As System.Data.DataRow Implements IHelpSC.SelectedRow
strDiscipline = Trim(discipline)
Dim cmdSelect As SqlCommand = sqlcnn.CreateCommand
Dim drResult As DataRow
Dim strQuery As String = "SELECT * FROM " & strDiscipline & _
" WHERE CallID=" & id
command.CommandText = “SELECT UserName from Users WHERE UserID = “ = userID
Executing this command returns one table with one column with one row. What is the syntax for getting that value into a variable? I can get the information into a dataSet but I can’t get it out. Should I be using a dataSet for this operation?
The rest of the code so far:
SqlDataAdapter dataAdapter = new SqlDataAdapter(); dataAdapter.SelectCommand = command; dataAdapter.TableMappings.Add("Table", "Users");
dataSet = new DataSet(); dataAdapter.Fill(dataSet);
Hi, i m pretty new to this forum and c#.net i m doin a project in c#.net I have four values in my datarow array for example DataRow[] cmb; cmb=dsResult.Tables[0].Select("Controls Like 'cmb%'");// Here i m getting four Rows

How to assign my session values to them. I want to assign my value stored in the session variable to that array.Is there any way i can do it.Can i convert datarow array to string array! Please can any one help me.
In my BLL I have a method that adds a new row to a table in the database... [System.ComponentModel.DataObjectMethodAttribute(System.ComponentModel.DataObjectMethodType.Insert, true)] public bool AddContact(string firstname, string lastname, string middleinit, bool active, Guid uid, bool newsletter) { ContactsDAL.tblContactsDataTable contacts = new ContactsDAL.tblContactsDataTable(); ContactsDAL.tblContactsRow contact = contacts.NewtblContactsRow(); contact.FirstName = firstname; contact.LastName = lastname; contact.MiddleName = middleinit; contact.Active = active; contact.UserID = uid; contact.Newletter = newsletter; contacts.AddtblContactsRow(contact); int rowsAffected = Adapter.Update(contact); return rowsAffected == 1; } The primary key in this table is a BigInt set as an identity column....How do I capture the value of the primary key that gets created when the new row is added?

Hi. I am new to ADO.NET and I can't seem to figure out how to populate a row that is a layer lower than the instantiated row. I am populating and XML file called Users.xml:
and, i am using the below code to access and populate the rows based on the users registration input:
Code:
Dim NewLogin As Data.DataRow = LoginDS.Tables(0).NewRow
I am able to access all the rows that are one layer into the xml file with the following code:
Code:
NewLogin("someNode") = _someNode.Text
but, how do i populate nodes that are "further down" such as "birthDay". Do i have to reinstantiate NewLogin as ...Tables(1).NewRow? I have tried various forms of this and it doesnt work. Suggestions appreciated... thanks.
I have a question regarding a locking scheme in MSSQL I hope you guys can help. In Sybase, I am able to specify datarow locking in DDL (ex. create table, alter table). Can I do the same in MSSQL or is there an equivalent option in CREATE TABLE statement in MSSQL? I came across a few articles in MSDN about datarow locking and it seems to me that MSSQL only allows locking through DML... Is that true? Thanks.
a while back i had to do a project with an access database, one of the biggest problems i had back then was gettting the primary key of a datarow you had just inserted into the database.
After a long set of trial and error i came up with the following:
- add the tablemappings of a table - call the dataadapte.fillschema method
then after inserting a new row into the database the primary key gets filled in automatically!
now thing is
i was hoping to duplicate this in sql server
but it doesn't seem to work at all
so after i insert a row into my datatable and update it the row is in the database but in vb the datarow primary key is not filled in! anyone have an idea?
prefereabely one that does not resort to stored procedures with return parameters etc
I will attempt to explain my situation more clearly.
I need to get data from a data source using a DataFlow Task (which pushes the DataSet into a Variable) and process the data row by row in a ForNext (ADO Enumerated) Container. I don't want to map the columns into variables because the number of columns and the data types vary considerably and I want to make my package as "generic" as possible.
Is there a way, in Script, to read the current row of the ForEach Container from into an ADO DataRow so that thie names and values of each column can be accessed?
I know how to read the entire DataSet object from a Variable into an ADO DataSet and iterate through the rows in the normal way but this doesn't suit my purpose. It would be really useful if there was a way to do somehing similar with the current DataRow in the ForEach Container.
To explain what I am doing, the idea is to use the Column Names and Values for each row to construct an xml fragement, store it in a string Variable and (in the next step) use the Web Services Task to call a Web Method with the xml fragment (from the Variable) as one of the inputs.
A less attarctive alernative would be to use a Scipt outside a ForEach Container and loop through the rows of teh DataTable as descibed above and perhaps call the Web Service Task from teh Script. The proble is that I don't know how to do this either and it woudl be much "neater" anyway to use the ForEach Container.
I am opening a simple command against a view which joins 2 tables, so that I can return a column which is defined as a tinyint in one of the tables. The SELECT looks like this: SELECT TreatmentStatus FROM vwReferralWithAdmissionDischarge WHERE ClientNumber = 138238 AND CaseNumber = 1 AND ProviderNumber = 89 The TreatmentStatus column is a tinyint. When I execute that above SQL SELECT statement in SQL Server Management Studio (I am using SQL Server 2005) I get a value of 2. But when I execute the same SQL SELECT statement as a part of a SqlDataReader and SqlCommand, I get a return data type of integer and a value of 1. Why?
I hvae a stored procedure that has this at the end of it: BEGIN EXEC @ActionID = ActionInsert '', @PackageID, @AnotherID, 0, '' END SET NOCOUNT OFF
SELECT Something FROM Something Joins….. Where Something = Something now, ActionInsert returns a Value, and has a SELECT @ActionID at the end of the stored procedure. What's happening, if that 2nd line that I pasted gets called, 2 result sets are being returned. How can I modify this SToredProcedure to stop returning the result set from ActionINsert?

I have a web application that is data driven from a SQL 2005 database. The application needs to prompt the user to enter some information that will be logged into a SQL table. It should always be the last row in the table that is being worked on at any one time. Over a period the user will need to enter various fields. Once the data is entered into a field they will not have access to amend it. Therefore I need to be able to SELECT the last row of a table and present the data to the user with the 'next field' to be edited. As I'd like to do this as a stored procedure which can be called from an ASP page I wonder if anyoen might be able to help me with some T-SQL code that might achieve it? Regards Clive

Hello, Im currently working on a asp.net file hosting wesite, and im being faced with some problems I currently have 4 sql tables. DownloadTable, MusicTable, ImageTable and VideoTable. Each of those tables contain a UserName column, a fileSize column and sme other columns. What i want to do is add up all the values in the fileSize column, for each table, and then add them up with the tables, and return one value, and all this happens where the UserName column corresponds to the UserName of the currently logged on User. I already have an sql statement that performs this exact thing. It is as follow select TotalDownLoadSize = sum(DownloadSize) + (select sum(VideoSize) from VideoTable where ([UserName] = @UserName ) ) + (select sum(ImageSize) from Images where ([UserName] = @UserName) ) + (select sum(MusicSize) from MusicTable where ([UserName] = @UserName) ) from DownloadTable where ([UserName] = @UserName) But the problem is that all of the tables have to have a value in there size columns for the corresponding user, for this sql statement to return something. For example, lets say i logged in as jon. If, for the UserName jon, the sum of DownloadTable returned 200, the sum of VideoTable returned 300, the sum of MusicTable returned 100. The sql statement i stated above will return 4 instead of 600, if the sum of ImageTable returned zero. Is there way around this? Im not sure if ive been cleared enough, please feel free to request more info as needed. Thank you very much, and thx in advance.
I have a stored procedure that does all the dirty work for me. I'm just having one issue. I need it to run the total number of RECORDS, and I need it to return the total number of new records for TODAY. Here is part of the code:SELECT COUNT(ID) AS TotalCount FROM CounterSELECT COUNT(*) AS TodayCount FROM Counter WHERE DATEPART(YEAR, visitdate) = Year(GetDate()) AND DATEPART(MONTH, visitdate) = Month(GetDate()) AND DATEPART(DAY, visitdate) = Day(GetDate())The statement works great, I just need to return TotalCount and TodayCount in one query. Is this possible?
Okay so here's a wierd one. I use SQLYog to peek into/administrate my databases.I noticed that this chunk of code is not producing a value... Using Conn As New MySqlConnection(Settings.MySqlConnectionString) Using Cmd As New MySqlCommand("SELECT COUNT(*) FROM tbladminpermissions WHERE (PermissionFiles LIKE '%?CurrentPage%') AND Enabled=1", Conn) With Cmd.Parameters .Add(New MySqlParameter("?CurrentPage",thisPage)) End With Conn.Open() Exists = Cmd.ExecuteScalar() End Using End Using Exists is declared outside of that block so that other logic can access it. thisPage is a variable declared outside, as well, that contains a simple string, like 'index.aspx'. With the value set to 'index.aspx' a count of 1 should be returned, and is returned in SQLYog. SELECT COUNT(*) FROM tbladminpermissions WHERE (PermissionFiles LIKE '%index.aspx%') AND Enabled=1 This produces a value of 1, but NO value at all is returned from Cmd.ExecuteScalar(). I use this method in MANY places and don't have this problem, but here it rises out of the mist and I can't figure it out. I have no Try/Catch blocks so any error should be evident in the yellow/red error screen, but no errors occur in the server logs on in the application itself. Does anybody have any ideas?
Hi everybody, I have a stored procedure that creates some temporary tables and in the end selects various values from those tables and returns them as a datatable. when returning the values, some fields are derived from other fields like percentage sold. I have it inside a Coalesce function like Coalesce((ItemsSold/TotalItems)*100, 0) this function returns 0 for every row, except for one row for which it returns 100. Does that mean for every other row, the value of (ItemSold/TotalItems)*100 is NULL ? if so, how can I fix it ? any help is greatly appriciated. devmetz

I have a stored procedure that inserts a record. I call the @@Identity variable and assign that to a variable in my SQL statement in my asp.net page.
That all worked fine when i did it just like that. Now I'm using a new stored procedure that inserts records into 3 tables successively, and the value of the @@Identity field is no longer being returned.
As you can see below, since I don't want the identity field value of the 2 latter records, I call for that value immediately after the first insert. I then use the value to populate the other 2 tables. I just can't figure out why the value is not being returned to my asp.net application. Think there's something wrong with the SP or no?
When I pass the value of the TicketID variable to a text field after the insert, it gives me "@TicketID".

We just upgraded to SQL 7.0 SP2. We enlarged one of our fields from varchar(255) to varchar(500), but when I do a SELECT on the field it only brings back 255. I know this was a limitation in ISQL in 6.5. I tried it in query analyzer and also via a command line. Any ideas how to see all the data?
