Hi everybody,How is it possible to close any open connections from the connection pool explicitly like on the log off page? So when the users log off from the application I want to close all connections that were opened during the use of application.asp.net forums is the best....thanks,Murthy here
should u always close everys sqldatasource connection string and the dataset associated with it, if so how do u do that (ie the proper way) and is it possible to to do it in the session area of global.aspx, NEt 2.0 or should it be done when exiting the page containing the data stuff, also same question for NET 1.0 datasets and adapters and strings,
I created this trigger on a table that i think failed while execution. I tried to modify it and run it again but it seems that i cant do that. If i try and delete the database i also cant - saying that it is still in use. But i am not using it and ther are no other users connected to it. I think the trigger has probably hit a loop and that is holding the link.
To close that i know that a solution would be to restart the SQL server instance but that would be a bit hard since the SQL server where my test database resides is a production server and has few other databases that are important and few users use them.
Is there any way through a SQL statement that there can be forced a delete? Or force close all the connections? Or force close all the processes without actually restarting the SQL server instance.
I have tried all options that were offered on some other forums like forcing it to a single user but even that operation can not be performed saying that the database is still in use.
In SQL Server Management Studio, it is possible to do the following:
a) In Object Explorer, connect to a particular SQL Server Database Engine, let's call it X. b) Use that connection to generate many SQL queries, connected to X, in the right-hand pane. c) In Object Explorer, connect to a particular SQL Server Database Engine, let's call it Y. d) Use that connection to generate many SQL queries, connected to Y, in the right-hand pane. e) Close the connection to X, which was created in step (a), from within Object Explorer.
In the right-hand pane, I am now left with a bunch of queries connected to X, and a similar bunch of queries connected to Y. Any quick way to shut all the queries connected to X, but none of the queries connected to Y?
This question can assume real practical importance if server X is a Live Production Server, and server Y is a Test Server, and my next job of the day is to run a change script against server Y....
I have looked for an option in Management Studio to "Close all queries connected to Server X", but haven't found one.
Just a quick question about connection management. My application willnever need more than 1 or 2 connections about at any given time. Also, I donot expect many users to be connected at any given time. For efficiency, Iwould like to keep connections alive throughout the lifetime of the objectsrequiring them, rather than opening a new connection, executing code andthen closing it again. What is the most efficient way of doing this?Should I perform the open/close or just one open when I create the objectand a close when I dispose of it?
I am getting the following error when creating a endpoint (that will be used for allwayson) The Database Mirroring endpoint cannot listen for connections due to the following error: '10049(The requested address is not valid in its context.)'.
My physical network card is configured with:
10.9.255.170
and iam creating my endpoint with 10.9.255.82
The creation of endpoint is being done with;
CREATE ENDPOINT [Hadr_endpoint] AS TCP (LISTENER_PORT = 5022, LISTENER_IP = (10.9.255.82) FOR DATA_MIRRORING (ROLE = ALL, ENCRYPTION = REQUIRED ALGORITHM AES) GO IF (SELECT state FROM sys.endpoints WHERE name = N'Hadr_endpoint') <> 0 BEGIN ALTER ENDPOINT [Hadr_endpoint] STATE = STARTED END GO use [master] GO GRANT CONNECT ON ENDPOINT::[Hadr_endpoint] TO [account] GO
we have roughly 22 people connected to one database. But after a while, their applications begin to drag due to in and out communication with the server. When i check the active connections on the sql server, some times i see 157 active connections, please how to i set a timeout or connection interval close, so as reduce the heavy load being put on the server. Or how can i automatically close connections when they get higher than 50 connections.
I would like to restore database using RESTORE DATABASE ... REPLACE command. If database exists already and has any open connections this command will fail. I would like to close all existing connections to specific database before running RESTORE DATABASE ... REPLACE command. I can do closing from Management Studio using checkbox "Close Existing Connection" when deleting database. Actually I need to do the same but from script.
Hi there, Here we have got a asp.net application that was developed when database was sitting on SQL server 6.5. Now client has moved all of their databases to SQL server 2000. When the database was on 6.5 the previous development team has used oledb connections all over. As the databases have been moved to SQL server 2000 now i am in process of changing the database connection part. As part of the process i have a login authorization code. Private Function Authenticate(ByVal username As String, ByVal password As String, ByRef results As NorisSetupLib.AuthorizationResult) As Boolean Dim conn As IDbConnection = GetConnection() Try Dim cmd As IDbCommand = conn.CreateCommand() Dim sql As String = "EDSConfirmUpdate" '"EDSConfirmUpdate""PswdConfirmation" 'Dim cmd As SqlCommand = New SqlCommand("sql", conn)

But in the authenticate method above at the line Dim ReturnValue As String = cmd.ExecuteScalar.ToString
for some reason its throwing the below error. Run-time exception thrown : System.Data.SqlClient.SqlException - @password is not a parameter for procedure EDSConfirmUpdate. If i comment out the Dim conn As IDbConnection = New System.Data.SqlClient.SqlConnection and uncomment the .net oledb provider, Dim conn As IDbConnection = New System.Data.OleDb.OleDbConnection then it works fine. I also have changed the webconfig file as below. <!--<add key="Common" value='User ID=**secret**;pwd=**secret**;Data Source="ESMALLDB2K";Initial Catalog=cj_common;Auto Translate=True;Persist Security Info=False;Provider="SQLOLEDB.1";' />--> <add key="Common" value='User ID=**secret**;pwd=**secret**;Data Source="ESMALLDB2K";Initial Catalog=cj_common;' />
Hi, I've created a simple hit counter in my Session_Start event... Dim myDataSource As New SqlDataSourcemyDataSource.ConnectionString = ConfigurationManager.ConnectionStrings("DatabaseConnectionString1").ToStringmyDataSource.UpdateCommand = "UPDATE Stats SET Hits = Hits + 1"myDataSource.Update() It works fine but do I need to close the connection after I've finished with it or is this ok? Thanks for your help.
I am trying to select rows from a SQL2000 database table and then write a random number back into each row. I have already looked into do it all in a SP but there are well documented limitations for the SQL RAND function when called in the same batch, so I need to somehow do in .Net what I already have working in classic ASP. I can't get the UPDATE (part two section) to compile. I don't know how to call the stored procedure inside the 'foreach' loop or extract the SP parameters. I have it working in classic asp but am having a lot of trouble converting to .Net 2.0. Is the below even close to working? // stored procedure to write externally generated random number value into database PROCEDURE RandomizeLinks@L_ID int,@L_Rank intASUPDATE Links SET L_Rank = @L_RankWHERE (L_ID = @L_ID) // Part One select links that need random number inserted. public DataTable GetRandLinks() { SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["ConnectionString1A"].ConnectionString); SqlCommand cmd = new SqlCommand("RandomizerSelect001", con); cmd.CommandType = CommandType.StoredProcedure; SqlDataAdapter da = new SqlDataAdapter(); da.SelectCommand = cmd; DataSet ds = new DataSet(); try { da.Fill(ds, "Random001"); return ds.Tables["Random001"]; } catch { throw new ApplicationException("Data error"); } } // Part Two I need two write a random number back into each row protected void Button1_Click(object sender, EventArgs e) { GetRandLinks(); int LinkID; // this generates unassigned local variable "LinkID' error int LRank; // this generates unassigned local variable "LRank' error SqlConnection con2 = new SqlConnection(ConfigurationManager.ConnectionStrings["ConnectionString1A"].ConnectionString); SqlCommand cmd2 = new SqlCommand("RandomizeLinks", con2); cmd2.CommandType = CommandType.StoredProcedure; cmd2.Parameters.AddWithValue("@L_ID", LinkID); cmd2.Parameters.AddWithValue("@L_Rank", LRank); SqlDataAdapter da2 = new SqlDataAdapter(); int RowIncrement; RowIncrement = 0; DataTable dt = GetRandLinks(); foreach (DataRow row in dt.Rows) { System.Random myRandom = new System.Random(); int LinkRank = myRandom.Next(25, 250); LRank = LinkRank; da2.UpdateCommand = cmd2; RowIncrement++; } }
If this is used eg. Return selectCommand.ExecuteReader(CommandBehaviour.Default) Here do i need to close the connection in finally explicitly???? Are there any links which can answer this kind of question ??? Thanks for any help in advance.....
Hello, I'm trying to run the following snippet as Console app, and I get an error: "a reader is already open for this connection, and should be closed first" I tried to manually say: SqlDataReader.Close() in the begining of the code, but still get the error, Any suggecstions how to manually close the reader? thank you ---------- here's the code -----------using System; using System.Data; using System.Data.SqlClient; using System.Data.SqlTypes; namespace ADO.NET { /// <summary> /// Summary description for Class1. /// </summary> class Class1 { /// <summary> /// The main entry point for the application. /// </summary> [STAThread] static void Main(string[] args) { SqlConnection cn = new SqlConnection ("SERVER=MyServer; INTEGRATED SECURITY=TRUE;" + "DATABASE=AdventureWorks"); SqlCommand cmd1 = new SqlCommand ("Select * from HumanResources.Department", cn); cmd1.CommandType = CommandType.Text; try { cn.Open(); SqlDataReader rdr = cmd1.ExecuteReader(); while (rdr.Read()) { if (rdr["Name"].ToString() == "Production") { SqlCommand cmd2 = new SqlCommand("SELECT * FROM " + "HumanResources.Employee WHERE DepartmentID = 7", cn); cmd2.CommandType = CommandType.Text; SqlDataReader rdr2 = cmd2.ExecuteReader(); while (rdr2.Read()) { } rdr2.Close(); } } rdr.Close(); } catch (Exception ex) { Console.WriteLine (ex.Message); } finally { cn.Close(); } } } }
How do i close a current connection to a database using t-sql?I fail some time to drop the database getting messages that it'scurrently in use.Using the wizard to delete the database, i could check the option toclose all connections to the db, but how do i do it using t-sql?best regards
Then I Open the Connection. Now, in some ways I need to drop a Table. Before I do so, I disconnect the DB but I'm using only the line
cn.Close();
I saw om the Watch attributes that its not a real disconnect to the DB. When I try to Drop the Table I get this message: The system timed out waiting for a lock. [ Session id = 25,Thread id = -2096711882,Process id = -2090594918,Table name = Movies,Conflict type = x lock (s blocks),Resource = DDL ]
And the Table doesn't drop.
Is it related to the constructor line I made? What is the best solution to Drop a table..and then to get connected again with the DB.
I am trying to get my query to pull all the occurances where someone called 411 assistance. It pulls anything that has 411 in it right now, and I just need it to find where the number is just either '411' or '1411' and thats it. Here is what I have so far:
SELECT sum(PaidBalCost), sum(BonusBalCost), sum(ceiling((Cast(DurationSeconds as Decimal)/60))) as Minutes FROM VoiceCallDetailRecord WHERE CallDate >= '02/19/2007' and calldate < '03/19/2007' and (Left(Endpoint,3) = '411' or Left(Endpoint,4) = ('1411')) UNION SELECT sum(PaidBalCost), sum(BonusBalCost), sum(ceiling((Cast(DurationSeconds as Decimal)/60))) as Minutes FROM ZeroChargeVCDRecord WHERE CallDate >= '02/19/2007' and calldate < '03/19/2007' and (Left(Endpoint,3) = '411' or Left(Endpoint,4) = ('1411'))
we've gotten this to work from sqlclr and understand the dependence wcf has on the framework but still feel compelled to ask if somehow t-sql can send a message to a wcf endpoint without getting sqlclr involved. I've moved this question over here from the t-sql forum.
I have created an Endpoint based on a stored procedure that has a parameter of datatype XML. I have added a reference to the endpoint in a web project, I have no problems accessing but I do have a question on how to pass XML or an entire XML file to the XML datatype? How is this done in VB.net? I have loaded the XML file into a vb string but this is not compatible with the sql server xml datatype? Any examples anywhere?
I have two servers both installed sql server.The name of the servers are A and B respectively. The admin of sql server in A is 'domainuserA', and admin of sql server B is 'domainuserB'.
My purpose is create a mirroring for a database in server A, but i can establish endpoint in server A(network address can not be reached or does not exist), i have grant the 'connect to endpoint' permission to each login .
i past my code:
step1
Code Snippet --Server A, principal create database db_test backup database db_test to disk='\sharefolderdb_test.bak' with init
create endpoint endpoint1 as tcp(listener_port=5002) for database_mirroring (role=partner)
alter endpoint endpoint1 state=started
create login [domainuserB] from windows grant connect on endpoint::endpoint1 to [domainuserB]
step2
Code Snippet --Server B, mirror restore database db_test from disk='\sharefolderdb_test2.bak' with norecovery
create endpoint endpoint1 as tcp(listener_port=5002) for database_mirroring (role=partner)
alter endpoint endpoint1 state=started
create login [domainuserA] from windows grant connect on endpoint::endpoint1 to [domainuserA]
alter database db_test set partner='TCP://A.corp.com:5002'
--step3
Code Snippet ----Server A, principal
alter database db_test set partner='TCP://B.corp.com:5002'
this step return a error message:
The server network address "TCP://B.corp.com:5002" can not be reached or does not exist. Check the network address name and that the ports for the local and remote endpoints are operational.
I am trying to grasp endpoint security, or actually more security/certiicates in general, at the moment i am trying to write a distributed service broker app, all the examples i have seen use certificates for the endpoint authentication.
Why must one create a certificate at each endpoint? Why can i not create a single certificate and let all endpoints use it ?
As you can imagine of this app gets distributed to hundreds of places creating a certificate at each one is a mission?
So can i use a single certificate for all endpoints authentication?
I am inheriting all my webpages from a BasePage which is storing my sqlconnection to the database. I open the connection in the "protected override void OnInit()" method (is this right?) but I don't know where I should write the close the connection. Can anyone give me any suggestions? Regards EO
How do you close the connection at the SQL Server? I have a backup I want to resotre to SQLExpress using SQL Management Studio Express. When I try, the SQL tells me he can't because the database is in use. I don't realy care about this I still want to restore the database. So I figured it's because there are some active connection to the database. My gues is I have to close those, but how? I also know I can restart SQLExpress and the connection will drop, but this server has more then one database, so I cant always do that. I'm looking for some T-SQL like DROP ALL CONNECTION. Thanks for the help.
Hi,since yesterday I have this message everytime I try to open Sql Server"Enterprise manager"; I reinstalled the outfit completely without successany solutionthanksFernand
Given that the conversation states are as follows: (Thanks Rushi!)
Event Initiator Endpoint state Target Endpoint state
BEGIN DIALOG SO -- from Initiator to Target
SEND message(s) CO -- from Initiator to Target
Target receives a fragment CO SI of the first message sent or receives out of order message
Target received entire CO CO first message
END conversation at CO DO target
Initiator receives EndDialog DI DO message from target
Target receives ACK for the DI CD EndDialog message sent
END conversation at CD CD Initiator
When does the 30 minute timer start for clearing the conversation from the sys.conversation_handles table? Is it the same for both sides (initiator and Target) ie, the end conversation at the Initiator. I guess it must be just in case a resend is necessary.
Here's a code test I did place in the Form_Load of my C#.NET app.
SqlConnection cnn = new SqlConnection();
cnn.ConnectionString = "bla bla...";
cnn.Open();
cnn.Close();
cnn.Dispose();
In SQL SERVER PROFILER, the Audit Login takes place as soon as I hit the .Open() but when I hit the .Close() OR the .Dispose() there's no Audit Logout. The Audit Logout is issued only when I quit the application.
I write a .NET Windows Form that connect to SQLExpress datafile. After updating data, I want to zip the .mdf file and send email. However, I got an exeption that the .mdf file is used by other thread so I cant zip. Even I try to close all connection, I still cant zip.
Is there any way to detach/unlock .mdf file connecting by SQLExpress?
