AttachDBFileName Option In Connection String

Aug 23, 2007

I used the following connection string when working with a SQL server DB locally in an ASP.NET code-behind module:
dim source as string="data source=.SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|Registration.mdf;User Instance=true"

However, when I uploaded the application to a web server where my site is hosted, I spent considerable time debugging the "Cannnot establish connection" exception, I was getting.

After adding "Database=Registration.mdf;server=<server N/W address>" and removing
"AttachDBFilename=|DataDirectory|Registration.mdf;" from the connection string, the connection was finally established.

Now, I have two questions: What's the difference between database and attachDBFileName options (And when should I use which)?

Secondly, why I had to add the server option, when it worked fine locally, and the application & db are located on the same web server?

Cannot Set Connection Property Of Backup Database Task If Connection String Is Customized In Connection Object

Aug 23, 2006

I added a connection (ADO.NET) object by name testCon in the connection manager - I wanted to programmatically supply the connection string. So I used the "Expressions" property of the connection object and set the connectionstring to one DTS variable. The idea is to supply the connection string value to the variable - so that the connection object uses my connection string.

Then I added a "Backup Database Task" to my package with the name BkpTask. Now whenever I try to set the connection property of BkpTask to the testCon connection object, by typing testCon, it automatically gets cleared. I am not able to set the connection value.

Then after spending several hours I found that this is because I have customized the connection string in testCon. If I don't customize the connection string, I am able to enter the "testCon" value in the connection property of the BkpTask.

Is this an intrinsic issue?

AttachDBfilename

Dec 13, 2005

I was getting SQL Server errors trying to run the Time Tracker kit, so
I tried to establish a connection with the timetracker.mdf from the
VWD Database Explorer - but no luck:

Data Source: Microsoft SQL Server Database File (SqlClient)

Database File name: Visual Studio2005WebSitesTimeTracker1App_DataTimeTracker.mdf

Using either Windows or SQLServer authentication, they both fail when I test the connection.

Any ideas ? I gave myself and the ASPNET account every permission possible in SQLServer.

Invalid Value For Key 'attachdbfilename'.

Nov 8, 2006

HI,
We upgraded to SQL Server 2005 Standard Edition for our ASP.NET 2.0 website. We were using SQL Server Express 2005. That worked fine. Now we are unable to connect to the database. I have googled, but I just cann't figure out what is going on. Any help is appreciated. Here is the error.
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: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)
In our firewall sqlbrowser.exe and sqlservr.exe are allowed.
Thanks Matt

AttachDbFilename In SQL Server (not Express)

Nov 22, 2005

I've been working with VWD Express since its Beta 1, then Beta 2 and finally the final release.

With the Beta 2 I've been worked with crystalreports without any problem in connections to SQL Server 2000.

The problem arrives now: I'm working with godaddy.com (good guys)

They tell me to connect to my databases (SQLServer 2005) with this:

<connectionStrings>

<add name="Personal" connectionString="

Server=whsql-v04.prod.mesa1.secureserver.net;

Database=DB_675;

User ID=user_id;

Password=password;

Trusted_Connection=False" providerName="System.Data.SqlClient" />

<remove name="LocalSqlServer"/>

<add name="LocalSqlServer" connectionString="

Server=whsql-v04.prod.mesa1.secureserver.net;

Database=DB_675;

User ID=user_id;

Password=password;

Trusted_Connection=False" providerName="System.Data.SqlClient" />

</connectionStrings>

But I've been always using this:

<connectionStrings>
<add name="AppConnectionString1"
connectionString="Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|myMDF.mdf;
Integrated Security=True;
User Instance=True"
providerName="System.Data.SqlClient"/>
</connectionStrings>

Does it means that I cannot use "AttachDbFilename"? I mean, I can't use an attached db file?
Should I create all my tables another time? (they use a Web database Admin)

Thanks in advance.

Using Attachdbfilename In SQL Server Full Version

Feb 14, 2008

Hi,
After publishing my ASP.NET application from my local development machine to a server, I cannot get it to attach the database file to the SQL Server instance. The SQL Server is full version 2005. The error I receive 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: SQL Network Interfaces, error: 25 - Connection string is not valid)
My connection string is:
<add name="WiggleITAdminDBConnectionString1" connectionString="Server=.MSSQLSERVER;AttachDbFilename=|DataDirectory|ITAdmin.mdf; Database=ITAdmin;Trusted_Connection=Yes" />
My ASP.NET version information is:
Version Information: Microsoft .NET Framework Version:2.0.50727.1433; ASP.NET Version:2.0.50727.1433
According to http://forums.asp.net/t/966680.aspx the full version of SQL Server 2005 doesn't allow the word AttachDbFilename.
Our DBA tells me that there are ways to attach .mdf & .ldf files to a full SQL Server instance. Does anyone know how?
Can anyone resolve this dillema? All help will be greatly appreciated.

Sep 27, 2007

Hi,
I'm having a BIG problem, this is my 3rd day looking for answer !I'm trying to create a custom membership provider with MS SQL database 2005 but not the default ASPNETDB. I've changed the web.config to be as following:<connectionStrings><add name="sqlConn" connectionString="Data Source=.;Integrated Security=True;Initial Catalog=ASPNETDB;"providerName="System.Data.SqlClient" /></connectionStrings> <system.web><trace enabled="true" /><roleManager enabled="true" /><authentication mode="Forms" />

The Connection Name 'name' Was Not Found In The Applications Configuration Or The Connection String Is Empty

Jan 18, 2008

I have been trying to host my website on Go Daddy for about 3 weeks and I have cleared several problems but this one remains. I can get into the ASPNETDB database for doing logins , etc but I cant access my database called "PINEmgt".
To try to understand where the problem is located,I built a very simple application without login controls and put on it one Detailform accessing a single line table "Signin". I continually get the error message I got with my real app :"The connection name 'PINEMgtConnectionString2' was not found in the applications configuration or the connection string is empty. " There is only one connection string in my app -'PINEMgtConnectionString2'. When I run the app locally on my machine it works. After I move everything to Go Daddy, I get the error message and the following dump"

Line 24: </Fields>
Line 25: </aspetailsView>
Line 26: <aspqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStringsINEMgtConnectionString2 %>"
Line 27: InsertCommand="INSERT INTO Signup(first_name, last_name, email, customer_id) VALUES (,,,)"
Line 28: SelectCommand="SELECT * FROM [Signup]"></aspqlDataSource>

This is indeed the code from my single page app.

The dump is:

[InvalidOperationException: The connection name 'PINEMgtConnectionString2' was not found in the applications configuration or the connection string is empty.]
System.Web.Compilation.ConnectionStringsExpressionBuilder.GetConnectionString(String connectionStringName) +3039085

After Googleing, asking Go Daddy for info (which they dont give) , etc for three weeks, I need serious mental help
in the form of a solution of this problem. Your help with the problem or the name of a good mental health professional in eastern N.C. (maybe both) would be appreciated.

SQL Server 2008 :: Connection Manager Not Using Connection String Value

Feb 19, 2015

I have a child package where the ConnectionString property of a Connection Manager is set by a Parent Package Variable Configuration. I set up a script task that brings up a message box with the value of the ConnectionString property right before the dataflow task.

MessageBox.Show(Dts.Connections["CPU_*"].ConnectionString.ToString());When I run the parent package, the message box shows that the connection string is changing with every iteration, but in the dataflow it always draws the data from the same source.

The connection manager is an ADO.Net type, RetainSameConnection is set to False, and I've been researching this for days.

(Update 2/23/2015): To make this stranger, when I look at the diagnostic logs, they tell me that when the new connections are being opened they are using the new connection strings.

Edit Connection Manager Connection String At Runtime With C#

Jul 3, 2007

This is the first time I have used SSIS, so please bear with the ignorance.

I have a super simple package that inserts x000's of rows into a temporary table. The data source is a file that the user will upload. I need to be able to tell the package what file to upload. I'm thinking the simplest thing would be to edit the connectionString property of the SourceConnectionFlatFile at runtime. Is this possible? What form should the file path be in (UNC, other)? And, are there any other considerations I should be aware of?

Thanks!

In SqlServer Management Studio Express, Server Type Option Is Greyed Out, Also Publication Option Missing

Hi everyone In my SqlServer Management Studio Express, on start up it shows the server type option, but greyed.So that value is fixed to database engine. ( I'm trying to work on an SqlServer Compact Edition database through the SSMStudiothat's why I'm trying to get this to change.)Besides, after I connect i go to the Object Explorer, expand the server node, and go to Replication.When i expand replication, i get the "Local Subscription" option, but nothng for Publication.( I want to work on Merge Replication, that's why I desparately need Publication to work)Am i missing something here? I did not install SqlServer separately, I only have what comes bundled with the Visual Studio 2005 Setup.

Variable Connection String For OLE DB Connection

May 15, 2007

Good Morning,

I hope that I am just missing a step in the process somewhere. I have established a string variable called DatabaseServer and another called DatabaseName. In the OLE DB connectionstring expression I have the following:

Code Snippet

"Data Source=" + @[User::DatabaseServer] + ";Initial Catalog=" + @[User::DatabaseName] + ";Provider=SQLNCLI.1;Integrated Security=SSPI;Auto Translate=False;"

My understanding is that changing the variable from SERVERA to SERVERB should repoint the connection. (Test to pre-production to production in my current promotion environment.) This should also take effect in any dataflow task using the database connection above right? When I try to repoint the server variable (and only the server variable) I am either a.)throwing errors saying the original connection cannot be found in the data flow task, or b.)the job appears to be processing fine, but the repoint did not take place and data is still flowing to the original server.

Can anyone offer suggestions as to what I am missing?

The properties values in the DB connection:

ConnectionManagerType is OLEDB

DataSourceID is blank

DelayValidation is False (Setting to true changes nothing in my test)

Expression for ConnectionString is (see above)

RetainSameConnection is False

SupportsDTCTTransactions is True (and appears to be unchangeable.)

SQL 2012 :: Configuring Memory Per Query Option And Index Create Memory Option

Feb 10, 2015

So I started a new job recently and have noticed a few strange configurations. Typically I would never mess with min memory per query option and index create memory option configuration because i just haven't seen any need to. My typical thought is that if it isn't broke... They have been modified on every single server in my environment.

From Books Online:
• This option is an advanced option and should be changed only by an experienced database administrator or certified SQL Server technician.
• The index create memory option is self-configuring and usually works without requiring adjustment. However, if you experience difficulties creating indexes, consider increasing the value of this option from its run value.

My webpages give me the error that the server does not exist or access denied. When I use anything else like SQLNCLI.1 for the provider it gives me the error that the provider is not found. What should the connection string consist of and what should I use for Provider?

Connection String

Dec 3, 2007

Hi , I've been searching for this answer for a few hours now but unfortunately I still can not sort it.
I'm attempting to make a "Database Driven Hierarchical Menu" from this tutorial http://aspalliance.com/822
It explains in the tutorial that you must change the connection string to point to your database and add user name and password. (i dont have a user name or password for my local server, or atleast I dont think I do!)
Below is my connection string:DataSet ds = new DataSet();
string connStr = "server=localhost;Trusted_Connection=true;database=Product.mdf";using (SqlConnection conn = new SqlConnection(connStr))
{string sql = "Select MenuID, Text, Description, ParentID from Menu";SqlDataAdapter da = new SqlDataAdapter(sql, conn);
da.Fill(ds);
da.Dispose();

Every time I try to run the page I get this error.
Cannot open database requested in login 'Product.mdf'. Login fails.Login failed for user '*****'
Can anyone see where I'm going wrong? I'm quite new to all this so I apologies if this seems a bit stupid.
Many Thanks

Help With Connection String

May 2, 2008

Could someone help me with my connection string and how I should create it?
I have a Windows 2003 server running MS Sql 2005. This is a separate server, meaning I'm developing my ASPX code on my laptop and FTP the code over to the server. I'm not sure how to write my connection string. Should My current connection string point to my locally hosted DB. Now that I have my own server should I replace my current 'localhost' entry with the server's IP address? Do I need to create a DNS on the server? Sorry, I'm very new to all this and I'm lost. Any help would be greatly appricated.
