c# - Sql Server 2008 Closing Connections after database dropped -


I left a database and was rebuilt and next time I'm having trouble leaving the connection to SQL Server Try to execute an order against a new connection on the same database, I am getting:

A transport-level error occurred while sending a request to the server (Provider: Shared memory provider, Error: 0 - There is no process on the other end of the pipe.)

Here is the TCP version (if I try to connect to another server)

A transport-level error generated when sending a request to the server Hui. (Provider: TCP provider, Error: 0 - An existing connection was forcibly closed by remote host.)

These steps are taken to restore the problem:

  1. Open a connection to a database and execute a sql command
  2. Drop the database
  3. Rebuild the database
  4. One Open a new connection from the database

Result: I get an exception

Here's the code: 

  C; (var Conn = new System.Data.SqlClient.SqlConnection ("Data Source = Initial Catalog = DBNAME; Integrated Security = True")) {conn.Open (); Var cmd = conn.CreateCommand (); Cmd.CommandText = "UPDATE ..."; Cmd.ExecuteNonQuery (); } String SQL = "Database DBManet with Dual-set Single-User Rollback with Instant Drop Database"; Var Server = New Microsoft.SqlServer.Management.Smo.Server ("."); Server.ConnectionContext.ExecuteNonQuery (SQL); Server.ConnectionContext.Disconnect (); Sql = file Read all the text ("Pathotodsfilefile ..."); Server = New Microsoft.SqlServer.Management.Smo.Server ("."); Server.ConnectionContext.ExecuteNonQuery (SQL); Server.ConnectionContext.Disconnect (); (Var conn = new System.Data.SqlClient.SqlConnection ("Data source =. Initial catalog = WER_CONFIG; coordinated security = true")) (conn.Open (); var cmd = conn.CreateCommand (); Cmd.CommandText = "UPDATE ..."; cmd.ExecuteNonQuery ();}

The error occurs at the very end of the 'cmd.ExecuteNonQuery ()' line. It appears that even if I Every time I connect, I'm creating a new connection, SQL Server keeps some (or possibly Adonet code) views, where next time I ask for a connection, it gives me one Which is already used or has been turned off on the server side.

Note that if I do not do this then it has been turned off on the server (probably due to that database This is being omitted).

The first step to execute the initial query, and I just leave the database, make it again, and execute an order, I did not get this error I think that from the database. Establishing initial connection is an important part of this error.

I have also tried to use an external process that can recreate and reproduce the database: 

  ProcessStartInfo info = new ProcessStartInfo ("sqlcmd .exe "," -eE -S--Q "" restore database DBNAME set instant drop database with single-user rollback DBMNA \ "); Var p = Process Start (notification); P.WaitForExit (); Info = New ProcessStart Infos ("sqlcmd.exe", "-i" + Pathotodsfilefile); P = Process Start (info); P.WaitForExit ();

And this did not help.

Is there a way to create a new SQL connection and is it sure that it is not from the pool? Any other suggestions about solving this problem?

Update: The problem was solved by using SqlConnection.ClearPool (), but I just decided to edit my connection string with pooling = false, whatever worked.

You can try to stop this behavior by adding pooling = false as a parameter to your connection string.
