Benefits Of Using SqlCommand.ExecuteNonQuery?
Mar 29, 2010a) SqlCommand.ExecuteNonQuery is used for update, insert and delete operations.
Besides the fact that by using ExecuteNonQuery instead of ExecuteReader we automatically know there won't be any query results returned, are there some other benefits/reasons why ExecuteNonQuery should be used?
b) Similarly, if we want a database operation to return a single value, we should use ExecuteScalar instead of ExecuteNonquery ,where with the latter result would be returned via SqlParameter. Is there any particular reason why we should prefer ExecuteScalar over ExecuteNonQuery?

Aug 4, 2010I've got a routine that's supposed to be capturing data from an XML to a DataTable (which works fine), and then using that data to insert into MS SQL. I have no problems with the Inserting of records (via a different routine) but am struggling to update existing records - I'm not even getting any errors, and I can verify that the data is being assigned to the parameters.
Here's what I've got.

DataSource Controls :: Why Does Cmd.ExecuteNonQuery() Return -1
Mar 3, 2010I have created a stored procedure that reset my tables' identity value. The store procedure works fine when I didrectly run it in my ms sql server 2008. It reset my table Identity value However, when I call it from my function reset, it returns -1, and does not reset my table identitity value. The function to restet my identity value is:
[Code]....
My stored procedure is
[Code]....
To call the the function:
Dim result

util.print(result)
I got result is -1, and it does ot reset my table identity. Why? How to resove it?
ADO.NET :: ExecuteNonQuery Trimming Return Parameter Value?
Sep 6, 2010I am observing a rather strange behavior. I have a procedure which selects a field from a matching record and returns it. The procedure works as expected returning proper values, when I execute the procedure from Visual Studio Server Explorer tab. The procedure is
[Code]....
This is being called from the DAL as follows:
[Code]....
The problem is if @ReturnValue is EAE then cmd.Parameter[outputParameterKey].Value is giving the value "E". If @ReturnValue is "Sassyboy" it is giving "S". why this behavior?
AJAX :: UpdateProgress Control With ExecuteNonQuery?
May 18, 2010I need to write a single web page that checks the status of an SQL job, and allows the user to execute a new job if the job has a specific status.
I have the job status checking code working but have a problem when it comes to the execution of the next job. The problem is because as soon as ExecutNonQuery is run my code goes straight to the next line leaving SQL to do its own thing - therefore my UpdateProgress never shows. How do I get the UpdateProgress control is be aware that my Job is still running??
I also have a method called ReturnJobDetailStatus which I imagine I could use by continually checking it with a combination of the UpdateProgress control and a timer control? If so I cannot visualise how to achieve this?
Here is a snippet of the code:

int count = Convert.ToInt32(_cmd.ExecuteScalar());
if (count > 0)

Session["Login"] = true;

ADO.NET :: ExecuteNonQuery Using Stored Procedure Will Not Delete Record (SQLDataAdapter)
Sep 6, 2010I'm using VB.net 2.0 with a SQL server (2005) backend db. I've got a very odd problem. I'm trying to use a stored procedure with a parameter to delete a record from a table. I've tested the stored procedure by running it directly from visual studio and it works fine, but when running it through my application nothing happens. There's no error and it appears to have worked but the record is not deleted.
I've checked permissions on the backend db and giving the network ASPNet account the db owner role has no effect either.
Here's the code, there are 3 layers - the webform code, then the business logic class, then the dataconnection class.
'firstly the original code that is run from the webform when the user selects to delete the record
Partial Public Class NewPerson
Inherits System.Web.UI.Page

Private currentNewRequest As New NewRequest(newConn)

Dim requestID As Integer = CInt(Me.lblRecordID.Text)
Me.currentNewRequest.newRequestID = requestID
Me.newConn.openConnection()
Me.currentNewRequest.DeleteRecord()
Me.newConn.closeConnection()
End Sub
End Class
'the business logic class that is called to set the parameters etc. The newRequestID integer is set at 19, I have checked this out.
Public Class NewRequest
Private dBConnection As DBConnection
Public newRequestID As Integer
Public Sub New(ByVal dBConnection As DBConnection)
'check params
If dBConnection Is Nothing Then
Throw New ArgumentNullException("dBConnection")
End If
Me.dBConnection = dBConnection
End Sub
Public Sub DeleteRecord()
'This sub deletes a request
With Me.dBConnection
.AddParameter("@newrequestID", SqlDbType.Int, 0, newRequestID)
.ExecNonQuerySP("sp_DeleteNewRequest")
End With
End Sub
End Class
'then the data connection class
Imports System.Data.SqlClient
Public Class DBConnection
Private _ParamList As SqlParameterCollection
Private _MyComm As New SqlCommand
Private _ConnectionStr As String = ConfigurationManager.ConnectionStrings("Conn").ToString
'shared connection
Dim conn As New SqlConnection(_ConnectionStr)
'the parameter is added
Public Sub AddParameter(ByVal ParamName As String, ByVal paramType As Data.SqlDbType, ByVal Paramlength As Int16, ByVal ParamValue As String)
MyComm.Parameters.Add(ParamName, paramType, Paramlength)
If ParamValue = Nothing Or ParamValue = "00:00:00" Or ParamValue = "" Then
_MyComm.Parameters(ParamName).Value = DBNull.Value
Else
_MyComm.Parameters(ParamName).Value = ParamValue
End If
End Sub
'and this is where the stored procedure is supposed to run, no errors are generated
Public Sub ExecNonQuerySP(ByVal SPName As String)
Dim MyAdapter As New SqlDataAdapter(_MyComm)
_MyComm.CommandType = CommandType.StoredProcedure
_MyComm.CommandText = SPName

End If
Try

Throw ex
Finally
End Try
End Sub
Public Sub openConnection()
conn.Open()
End Sub
Public Sub closeConnection()
conn.Close()

The stored procedure looks like this:

/*this sp is used to delete a new account request record*/
@newrequestID int
AS
DELETE FROM NewAccountRequest WHERE
NewRequestID = @newrequestID
Access :: Error : ExecuteNonQuery Requires An Open And Available Connection?
Apr 15, 2010We are currently migrating our test databases to a new server and I am switching one of our sites over to use them. When running the application from my development box it hits the database just fine. However when I compile and push the code out to our test server and try to use the same datbase I get the ExecuteNonQuery requires an open and available Connection. The connection's current state is closed error. I cannot seem to figure out why. Also when I point the site at our old test server it works just fine.

C# - Switch Between Databases / Use Two Databases Simultaneously?
Dec 28, 2010I have a web site which uses one SQL database but the hosting company is very slow sometimes and I got database timeout, login and similar errors. Can I implement my code to use two databases simultaneously? I have stored procedures and the data is updated periodically.
EDIT:
Simply: When dbDefault is down and inaccessible I need to use dbSecondary so the web app keeps running. Ant these two databases must be always same.
EDIT:
Some errors:
A transport-level error has occurred when sending the request to the server. (provider: TCP Provider, error: 0 - An existing connection was forcibly closed by the remote host.)A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached.Cannot open database "db" requested by the login. The login failed. Login failed for user 'root'.
