.NET and Closing MSSQL connections

- by user307076

I am having a hard time figuring out why the following constructor will not close connnections. When I view the active connections. Here is the code that I have. Public Sub New(ByVal UserID As Integer) Dim oConn As New SqlConnection(ConfigurationManager.ConnectionStrings("connStr").ToString()) Dim cmd As New SqlCommand("stored proc", oConn) Dim sdr As SqlDataReader cmd.CommandType = CommandType.StoredProcedure cmd.Parameters.AddWithValue("@userID", UserID) oConn.Open() sdr = cmd.ExecuteReader() Try If Not sdr.HasRows Then sdr.Close() If Not oConn Is Nothing Then If oConn.State <> ConnectionState.Closed Then oConn.Close() End If End If cmd.Dispose() Exit Sub End If 'User has account in WATS, proceed to load account information While sdr.Read _firstname = Convert.ToString(sdr("First Name")) _lastname = Convert.ToString(sdr("Last Name")) End While Catch ex As Exception 'Throw New Exception("User Error: " + ex.Message) Finally sdr.Close() If Not oConn Is Nothing Then If oConn.State <> ConnectionState.Closed Then oConn.Close() End If End If cmd.Dispose() End Try End Sub

ado.net managing connections

- by madlan

Hi, I'm populating a listview with a list of databases on a selected SQL instance, then retrieving a value from each database (It's internal product version, column doesn't always exist) I'm calling the below function to populate the second column of the listview: item.SubItems.Add(DBVersionCheck(serverName, database.Name)) Function DBVersionCheck(ByVal SelectedInstance As String, ByVal SelectedDatabase As String) Dim m_Connection As New SqlConnection("Server=" + SelectedInstance + ";User Id=sa;Password=password;Database=" + SelectedDatabase) Dim db_command As New SqlCommand("select Setting from SystemSettings where [Setting] = 'version'", m_Connection) Try m_Connection.Open() Return db_command.ExecuteScalar().trim m_Connection.Dispose() Catch ex As Exception 'MessageBox.Show(ex.Message) Return "NA" Finally m_Connection.Dispose() End Try End Function This works fine except it's creating a connection to each database and leaving it open. My understanding is the close()\dispose() releases only the connection from the pool in ado rather than the actual connection to sql. How would I close the actual connections after I've retrieved the value? Leaving these open will create hundreds of connections to databases that will probably not be used for that session.

How to pass the parameter in SQL query from PowerShell

- by Zshava

I have this code in PowerShell, that executes SQL query for UPDATE table: $Connection=new-object data.sqlclient.sqlconnection "server=server;database=mydb;trusted_connection=true;" $Connection.open() For( $i = 0; $i -le $ActID.Length; $i ++ ){ $cmd = New-Object System.Data.SqlClient.SqlCommand $cmd.Connection = $Connection $cmd.CommandText = " update Table set Note = @PATH " $cmd.Parameters.Add("@PATH", $ActID[$i].Values) | Out-Null $cmd.ExecuteNonQuery() } I try to update table with variable defined in this string: $cmd.Parameters.Add("@PATH", $ActID[$i].Values) | Out-Null But when i try to execute script, error log says that there is no value passed in $ActID[$i] Is there other methods to pass parameters (variables) in powershell queries?

Is there a difference SMO ServerConnection transaction methods versus using the SqlConnectionObject

- by YWE

I am using SMO to create databases and tables on a SQL Server. I want to do so in a transaction. Are both of these methods of doing so valid and equivalent: First method: Server server; //... server.ConnectionContext.BeginTransaction(); //... server.ConnectionContext.CommitTransaction(); Second method: Server server; // ...

Why is sql server giving a conversion error when submitting date.today to a datetime column?

- by kpierce8

I am getting a conversion error every time I try to submit a date value to sql server. The column in sql server is a datetime and in vb I'm using Date.today to pass to my parameterized query. I keep getting a sql exception Conversion failed when converting datetime from character string. Here's the code Public Sub ResetOrder(ByVal connectionString As String) Dim strSQL As String Dim cn As New SqlConnection(connectionString) cn.Open() strSQL = "DELETE Tasks WHERE ProjID = @ProjectID" Dim cmd As New SqlCommand(strSQL, cn) cmd.Parameters.AddWithValue("ProjectID", 5) cmd.ExecuteNonQuery() strSQL = "INSERT INTO Tasks (ProjID, DueDate, TaskName) VALUES " & _ " (@ProjID, @TaskName, @DueDate)" Dim cmd2 As New SqlCommand(strSQL, cn) cmd2.CommandText = strSQL cmd2.Parameters.AddWithValue("ProjID", 5) cmd2.Parameters.AddWithValue("DueDate", Date.Today) cmd2.Parameters.AddWithValue("TaskName", "bob") cmd2.ExecuteNonQuery() cn.Close() DataGridView1.DataSource = ds.Projects DataGridView2.DataSource = ds.Tasks End Sub Any thoughts would be greatly appreciated.

How to capture SQL with parameters substituted in? (.NET, SqlCommand)

- by Bryan

Hello, If there an easy way to get a completed SQL statement back after parameter substitution? I.e., I want to keep a logfile of all the SQL this program runs. Or if I want to do this, will I just want to get rid of Parameters, and do the whole query the old school way, in one big string? Simple Example: I want to capture the output: SELECT subcatId FROM EnrollmentSubCategory WHERE catid = 1 .. from this code: Dim subCatSQL As String = "SELECT subcatId FROM EnrollmentSubCategory WHERE catid = @catId" Dim connectionString As String = "X" Dim conn As New SqlConnection(connectionString) If conn.State = ConnectionState.Closed Then conn.Open() End If Dim cmd As New SqlCommand(subCatSQL, conn) With cmd .Parameters.Add(New SqlParameter("@catId", SqlDbType.Int, 1)) End With Console.WriteLine("Before: " + cmd.CommandText) cmd.Prepare() Console.WriteLine("After: " + cmd.CommandText) I had assumed Prepare() would do the substitutions, but apparently not. Thoughts? Advice? Thanks in advance.

Error: A SQLParamenter wtih ParameterName @myparm is not contained by this SQLParameter Collection

Good Morning, I'm working on an ASP.NET 3.5 webforms application and have written the following code: Protected Sub btnSubmit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSubmit.Click Dim connectionString As String = WebConfigurationManager.ConnectionStrings("Diel_inventoryConnectionString").ConnectionString Dim con As New SqlConnection(connectionString) Dim adapter1 As New SqlDataAdapter adapter1.SelectCommand = New SqlCommand adapter1.SelectCommand.CommandType = CommandType.StoredProcedure adapter1.SelectCommand.CommandText = "PartSproc" Dim parmNSN As New SqlParameter("@NSN", SqlDbType.NVarChar) Dim parmName As New SqlParameter("@PartName", SqlDbType.NVarChar) txtNSN.Text = adapter1.SelectCommand.Parameters("@NSN").Value txtSearch.Text = adapter1.SelectCommand.Parameters("@PartName").Value Dim dt As New DataTable() adapter1.Fill(dt) MySearch.DataSource = dt MySearch.DataBind() End Sub When I run the page, I receive the error A SQLParameter with @NSN is not contained by this SQLParameter Collection. I tried using apostrophes around the @NSN and @PartName but that does not work either and presents expression expected error. How might I rectify the above code so that it references the @NSN and @PartName parameters correctly? Thanks, Sid

"Cleanly" Deploying an ASP.NET Application with LINQ to SQL Server

- by Bob Kaufman

In my development environment, my SQL Server is PHILIP\SQLEXPRESS. In testing, it's ANNIE, and the live environment will have a third name yet to be determined. I would have assumed that updating the following statement in web.config would have been enough: <add name="MyConnectionString"providerName="System.Data.SqlClient" connectionString="Data Source=PHILIP\SQLEXPRESS;Initial Catalog=MyDtabase;Integrated Security=True" /> When using SqlConnection, SqlCommand, SqlDataReader and friends, that's all it took. Using LINQ, it doesn't seem to work that nicely. I see the servername repeated in my .dbml file as well as in Settings.settings. After changing it in all of those places, I get it to work. However if I'm doing a few deployments per day during testing, I want to avoid this regimen. My question is: is there a programmatic solution for LINQ to SQL that will allow me to specify the connection string once, preferably in web.config, and get everybody else to refer to it?

Why do SQL connection leave parameters in?

- by acidzombie24

While coding with sqlite everytime i always had the exact number of parameters and when i executed the query i always had 0 parameters after it. I kept using the cmd object and it worked fine. Now while porting to use sql server (2008) my SqlConnection has parameters left over from a successful command. Why? I seem to be able to create tables without the problem (then again i may have use a clone of an empty cmd since i use recursion). Does SqlCommand always leave the parameters in after a query? This always breaks the following query unless i do parameter.clear(). Should i create a new SqlCommand object? or use parameter.clear() each time? I'm somewhat confused.

"SQL Server does not exist or access denied." upon VB.Net Deployment

- by JasonMHirst

Have built a small VB.Net app in VS2010. The connection string to the SQL Server is as follows: <connectionStrings> <add name="IWSR_DataDownloadWizard.My.MySettings.sqlConnection" connectionString="Provider=SQLOLEDB.1;Data Source=SQLServer;Integrated Security=SSPI;Initial Catalog=IWSROL" providerName="System.Data.OleDb" /> </connectionStrings> Within the VS2010 environment AND on my machine, the connection works perfectly, however when I deploy to clients I get an error message of: [DBNETLIB][ConnectionOpen (Connect()).]SQL Server does not exist or access denied. I've tried to search the net for solutions, have seen a few instances of people saying to NOT use the Server Name but the IP Address instead (this doesn't work) and some saying to remove the "Provider=SQLOLEDB.1", again this doesn't work. Can anyone suggest a solution please? Further information: Development System is Windows7 using VS2010 Deployment systems are a combination of Windows XP, Windows 2000 and Windows 7 SQL Server is SQL2000 (soon to be SQL2005). TIA

vb.net : is it possible to connect to sql server 2008 via odbc but not through vb.net code?

- by phill

I'm supporting an old vb.net program whose database it connected to was moved from SQL Server 2005 to SQL Server 2008. Is there a setting on SQL Server 2008 which will allow ODBC connections to access the database but not allow VB.NET to connect to it programmatically? the error i keep receiving in the app is: An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 – Could not open a connection to SQL Server) however I can connect to it when I create a system dsn to the sql server instance and through VS2005's Tools Connect to Database. Here is the code I'm using to connect: dim strC as string strC = "data source=bob; database=subscribers; user id=bobuser; password=passme" dim connection as New SqlClient.SqlConnection(strC) try connection.open() catch ex as Exception msgbox(ex.message) end try connection.Close()
