SQLConnection.Open() Problem
Feb 14, 2008Hi,
When i run my script it gets about 5 lines before the bottom and kicks this out SQLConnection.Open()
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)
Does this mean that SQL Server 2005 Express doesnt allow remote connections and is there anything i can do to get round this (im running it locally)? My data Source is - SQLDataSource1 - Picturesdb.MDF and my local server is Localhost:1921. Code behind Below,

Open SQLConnection When Database Stopped
Dec 8, 2003I'm hoping someone can explain to me exactly what the SQLConnection.Open() method does, especially when the database is stopped. I'm trying to include some error processing in my program, specifically to ensure the database is up and running. But even with the database stopped, the Open() statement works fine. Later, when I try to read from the database, I get the error. I'd like to stop it before it gets any further. Why is the Open() statement "working" even with the database stopped?

Feb 11, 2008Hello, I started profiling a website that i'm developing yesterday (asp.net 2.0) and noticed that sqlconnection.open is ridiculously slow (between 3-10 seconds) when using integrated security=true in the connection string. If I use SQL authentication instead and pass the username and password in the connection string, sqlconnection.open is instantaneous.

How To Open Multiple SqlConnection Objects In A SqlServer Project
Jun 5, 2006I have a sql server project where I have added 1 stored procedure (named StoredProcedure1) and 1 class (named MyClass). MyClass has two functions Func1() and Func2(). The stored procedure simply instantiates MyClass and calls Func1().
Func1() creates a SqlConnection object using "context connection=true" - opens the connection and then calls Func2(). Func2() also creates a SqlConnection object using "context connection=true" - and attempts to open the connection. However when attempting to the Open() call inside Func2(), the code just exits. What gives? The code is pasted below, thanks!

Transaction Left In Open State On SQLServer 2000 And JDBC
Sep 6, 2007I have a problem where my connection always has an open transaction as viewed by activity monitor.
I am using the latest MS SQL Server 2005 JDBC driver (1.1) and connecting to SQL Server 2000.
This issue arises only when selectMethod=cursor and autoCommit is set to false. This issue does not exist when I connect to SQL Server 2005.
Has anyone else seen this issue?
How can this issue be resolved?
Thanks

ExecuteReader Requires An Open And Available Connection. The Connection's Current State Is Closed.
Apr 26, 2007I am accessing SQL2005 with C# code using OleDbConnection.
A try and catch block catches the following error once a while between the Open() and Close() of the connection:
ExecuteNonQuery requires an open and available Connection. The connection's current state is closed.
I do not even have any idea where to start to debug this. The ExecuteNonQuery() runs a delete SQL query. It works 99.9% of the time. I do not see anything wrong when this error happens.
Any hint would be greatly appreciated.
SQL Server Session State - Using A 1.1 Database Schema For 2.0 Session State Storage
Aug 3, 2006The 2.0 version of ASPSTATE is slightly different than the 1.1 version in that one table has one additional column and another table uses a different data type and size for the key. The 2.0 version also has a couple additional stored procedures.
We'd like to manage just one session state database if possible so we're trying to figure out if Microsoft supports using the new schema for 1.1 session state access (it seems to work, but our testing has been very light).
Is there any official support line on this? If not, can anyone comment on whether or not you'd expect it to work and why?
Thanks.
Principal Db In Principal, Synchronizing State, The Mirror In Restoring State
Sep 26, 2007We have mirroring setup for 5 dbs, 4 of which are synchronized and 1 which is in "synchronizing" state on the principal and "restoring" state on the mirror. Mirroring for all dbs has been working fine for the past several months and we have a witness that has allowed automatic failover in the past without problems.
This database has several bulk inserts performed throughout the day and am sure there is some latency due to the size of these transactions.
Not sure as to why this is happening all of a sudden, but the db in question has been in this state for the past 12 hrs. I checked the mirroring status on the principal and it states that it is "synchronizing: data is being transferred from principal to mirror", but the mirror server states that db is in "restoring" state. Can anyone suggest as to how I can get the database on the mirroring server to get back to "mirror, synchronizing/restoring..." state? Or suggest on how I can troubleshoot this?
Thanks in advance.
Cannot Open User Default Database. Login Failed. (only When IDE Is Open)
Sep 7, 2007I get the below error only when my IDE open. It connects well when it is found closed.
[SqlException (0x80131904): Cannot open user default database. Login failed.Login failed for user 'JPASPNET'.]
I could solve this by giving the logged in windows user to impersonate under IIS window > WEBSITE > ASP.NET tab > EDIT CONFIG > APPLICATION tab
But I wish someone could give me the proper solution.
I almost tried all from giving ASPNET user as a administrator to configuring the same in Express management tool.

Leave The Connection Open Or Always Open And Close Immediately?
Jun 7, 2006Hi there,
I got an approach like that:
1) Read something from DB - check the value, if true stop if false go on2) Read the second Value (another SQL Statement) - check the value etc.
Now I could open the connection at 1) and if I have to go to 2) I leave the connection open and use the same connection at 2). Is it ok to do that?
The other scenario would be opening a connection at 1), immediately close it after I read the value and open a new connection at 2).
Thanks for the input!

SqlConnection And Performance
Nov 16, 2006Hi there, I'm not sure if the way I handle SqlConnection in my apps is the most performant one.So my apps use db heavily and there are loads of classes with methods like 1 using (SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["myConn"].ConnectionString))
2
3 {conn.Open();
4 // more code here
5 }
6
7
As I use using the connection is closed and the object is disposed when leaving the code block.I know that the connection is taken from a pool and when closed it returns to the pool as though I'm not sure if it is better to have one "global" SqlConnection objectand to use that object for all classes or most of them. What about the ConfigurationManager, doesn't it slow down the performance as well when I'm accessing the ConnectionString value thousands of times?I hope someone can point out the issues.Many thanks in advance, Limbic
Sqlconnection Object
Jan 3, 2007I need some information on sqlconnnection object. I see it referenced in some exercises, and also displayed in the toolbox on some articles, but I'm running .net 2.0 and I have no sqlconnection in my toolbox, but more importantly, I can not seem to drop the data connection from my database/server explorer to my form to create a sqlconn object. When I highlight the data connection (in my case it's machinenamesqlexpress.pubs.dbo) and try to drag it - it immediately goes to a NO icon (that is a circle with a slash thru it) and I can not drop it onto my form. I can see the database with no problems in explorer.
I have been able to create a sqlconnection programatically:
Dim sqldatasource1 As SqlConnection = New SqlConnection()
sqldatasource1.ConnectionString = "Data Source=localhostsqlexpress;Initial Catalog=pubs;Integrated Security=True"
but how can I create it on my form?? I would appreciate any help on this matter.
(p.s. I am using VWD 2005 and SQLExpress)
SqlConnection Security
Jul 30, 2007I have created an aspx page that uses the SqlConnection class to pull data from Microsoft CRM’s database, and we have placed this aspx inside CRM’s directory on the server so that it uses the same integrated security that CRM uses. This works fine on our test environment but on our live environment the Sql connection fails with the exception: "Not associated with a trusted SQL Server connection"
This is probably because our test CRM server has the database on the same machine as the web server, but the live environment has the database and the web server on separate machines.
So my question is how can I create an aspx page that takes the integrated security credentials that the user used to log into the website and uses them to access data from a database on a seperate machine?

Dec 18, 2007I am working on a set of webforms that insert user data into a set of db tables.
I set up a test of an approach using northwind and I'm having trouble getting the insert to work. When I open the form, input the name and phone, and submit there is no error, but no record inserted into the Shippers table.
You can see one of my approaches in the ASPX code. I don't like having to do the select in order to do the insert -- so that's commented off.
I'm stuck. Thoughts about what I'm missing appreciated...

Reusing An SQLconnection
Nov 12, 2003Hi all,
I am accessing one database a bunch of different times all throughout my code...in various functions and different web pages. Is there a a way to create an sqlconnection that I can access all the time, instead of constanting hardcoding which database to go to? I've tried putting the info in another file and just including it where I want the database to open, but I can't use <!-- #INCLUDE --> inside of the server scripts.
Can anyone help
OleDbConnection Vs SqlConnection
Jan 22, 2004Hi,
How much of a performance difference is there between connecting to SQL Server 2000 using OleDbConnection or using SqlConnection?
The reason I'm asking is I am taking on the task of updating an older program that uses a Access Database to use SQL Server, but it has a Database Utility class that uses OleDbConnection. I'm just debating whether it would be worthwhile to upgrade the class to use the SQL objects rather than Oledb. Program does a lot of update and insert of invidual records, and a few select statements that usually return from 1 to 2000 records up to a maximum of 50,000 records
Thanks
SqlConnection Failed Sometimes
Mar 2, 2004I've an web app with impersonate windows authentication. IIS uses Windows authentication for this app & anonymous authentication is turned off.
This app have connectionString in Web.config where Windows autentication (SSPI) to SQL Server 2000 took place.
Now I've a piece of code:
public class SiteParameters
{
public static SqlConnection Connection
{
get
{
SqlConnection conn;
try
{
conn = new SqlConnection(ConfigurationSettings.AppSettings["connectionString"]);
if(conn.State != ConnectionState.Open)
conn.Open();
}
catch(Exception)
{
conn = null;
}
return conn;
}
}
}
No comments is needed, think...
Now, I'm going to use it in following way:
SqlConnection conn = SiteParameters.Connection;
SqlDataAdapter dta = new SqlDataAdapter();
DataSet ds = new DataSet();
SqlCommand sqlSelect = new SqlCommand("spPlanTransportSelect", conn);
sqlSelect.CommandType =CommandType.StoredProcedure;
dta.SelectCommand = sqlSelect;
dta.Fill(ds, "PlanTransport");
if(conn.State != ConnectionState.Closed)
conn.Close();
return ds;
It looks good & works good... on local machine only :( When I run app locally (doesn't matter if I call it by http://localhost/app, http://127.0.0.1/app or http://10.50.2.51/app I take proper data from database.
But when my buddy from another comp (e.g. 10.50.2.52) uses URL http://10.50.5.51/app he receives an error in line dta.Fill(ds, "PlanTransport");, but in fact conn variable is null & he receives "yellow" screen where is written that NT ANONYMOUS user is trying to log on to database...
It looks strange for me. Any tips?
