How To Connect To SQL Server Express 2005 Database At The Same Time From Both SSMSE And VB2005 Application ?

Jan 13, 2007

Here is the situation:

I have SQL server express 2005 installed on my pc as instance SQLEXPRESS.

I have created a Visual Basic applicaion with the following as connection to the SQL server express 2005 running on the same PC:
****************************************************************************************************
Dim lconnectionString As String Dim builder As New SqlConnectionStringBuilder Dim cmd As New SqlCommand Dim reader As SqlDataReader Dim parameter As SqlParameter builder("Data Source") = ".SQLEXPRESS" builder("Initial Catalog") = "" builder("AttachDbFilename") = "C:My DocumentsVisual Studio 2005Projectsabcabcabc.mdf" builder("Integrated Security") = True builder("User Instance") = True lconnectionString = builder.ConnectionString Dim sqlConnection1 As New SqlConnection(lconnectionString) cmd.CommandText = "SP_add_collection" cmd.CommandType = CommandType.StoredProcedure cmd.Connection = sqlConnection1 sqlConnection1.Open()
*******************************************************************************************************************

It seems that i can not connect to the abc.mdf in SSMSE while the VB program is running. (ERROR:
Database 'C:My DocumentsVisual Studio 2005Projectsabcabcabc.mdf' cannot be opened due to inaccessible files or insufficient memory or disk space. See the SQL Server errorlog for details. (.Net SqlClient Data Provider) )

If i connect to the abc.mdf first in SSMSE, then run the VB program afterwards, it gives me the error on this line -- sqlConnection1.Open()

I want to be able to access the abc.mdf database with both SSMSE and VB at the same time. Could anyone help me on this ?

Thanks very much !

How To Get A Web Application To Connect To SQL Server 2005 Express

Dec 12, 2006

All,
I'm a newbie here so forgive me if I have missed something completely obvious.
 I have bought a shopping cart script of a well known company (Evolve Merchant 5) and I wish to set it up locally on my development server, I created a virtual directory, set the web application up and get the asp pages to display perfectly. However, in the configuration file (global.asa & web.config) for the application it reguests information to be provided: <add key="DBName" value="Database name" />
<add key="DBServer" value="IP address of server" />
<add key="DBUserName" value="User name" />
<add key="DBPassword" value="password" />
<add key="AltPassword" value="password" />


 What I can't determine is what the SQL Server 2005's IP address is? the pages of this application show when I type http://localhost/catalogue into IE, so I presumed the server address would be the IP of localhost, when typed ping localhost into command promt it gives me 127.0.0.1, but when I enter this into the config file and try to load the application it just hangs and then eventually says:
"Microsoft OLE DB Provider for ODBC Drivers (0x80004005)[Microsoft][ODBC SQL Server Driver][DBNETLIB]SQL Server does not exist or access denied./catalogue/global.asa, line 54"
I have created a new database in SQL Express called: merchant509 and restored the tables to it as the manufactures help files state, I created a new login called shop which uses SQl authentication, so as I can provide a password. So the settings should look like this:
  <add key="DBName" value="Database name" />
<add key="DBServer" value="127.0.0.1" />
<add key="DBUserName" value="shop" />
<add key="DBPassword" value="1684" />
<add key="AltPassword" value="1684" />
 
But it doesn't work, does anyone know what i have done wrong?? the SQL server is runnign on the same computer as I am trying to access it from, it is set to accept all forms of comunication i.e. TCP/IP etc.. in the server configuration manager the IP address part of TCP/IP in protocols shows IP1 as 192.168.2.2 active yes enabled yes, and IP2 as 127.0.0.1 active yes and enables yes, I have tried the 192.168.2.2 and this gives the same errors, this is my registed IP on my home network.
 I'm now stumped, I haven't a clue what else I can try, I would be very greatfull if anyone has any ideas.
Regards,
Daniel Coates

Unable To Use SSMSE To Connect To SQL Express Server On Secondary IP Address

Apr 28, 2006

I am having trouble to use SSMSE to remotely connect SQL Express server using IPs other than the base IP of the machine.

Machine settings:

(1) Has multiple IP configured. Those IP are accessible remotely

(2) Firewall is not on.



SQL Express server configuration:

(1) TCP/IP and named pipe are on



Browser service state:

(1) running

(2) listening at 0.0.0.0:1434 (UDP)



SSMSE connection results:

(1) with <baseIP><instance>, connects OK

(2) with <otherIP><instance>, connection failed.

Both connections use exactly the same authentication information.



Testing results using telnet:

(1) telnet <baseIP> 1434, OK

(2) telnet <otherIP> 1434, OK



Does SSMSE actually only listen on the base IP even it shows to listen on all the IPs?

How Would You Set Up Boolean With SQL Server 2005 Express And Vb2005

Dec 19, 2006

Im used to using access and now im gonna switch to sql server 2005 express. My program is coded in Visual basic 2005 where all connection is made to the access database by oledb.

Now when im creating the database in management studio express, ive noticed that there is no boolean datatype, but instead there is a bit datatype.

Is this the one to use, and would the bit datatype accept true/false values when sending sql commands? In visual basic2005 i think that it uses 0 for true and -1 for false or something like that, so when switchin database i would have to recode quite a bit.

Or is simpler than this?

SQL Server Management Studio Express (SSMSE)=&&>Object Explorer=&&>Databases Has C:SSMSE-BookChapter12WINCH12NORTHWND.MDF?

Feb 27, 2008

Hi all,

In my SQL Server Management Studio Express (SSMSE)=>Object Explorer=>Databases, the "NORTHWND" database was screwed up and is deleted completely. But under the same Object Explorer =>Databases, there is a database "C:SSMSE-BookChapter12WINCH12NORTHWND.MDF". I need to use this "NORTHWND" database in the SqlConnection. How can I specify the "Initial Catalog" (or "database") in the New SqlConnection code statement (in the ADO.NET 2.0-VB 2005 Express programming)?
Should it be like the following:

Dim sqlConnection As SqlConnection = New SqlConnction("Data Source=.SQLEXPRESS; Initial Catalog=C:SSMSE-BookChapter12WINCH12NORTHWND; Integrated Security=SSPI;") ? Or what is the right code statement for connecting to it?

Please help and advise.

Thanks in advance,
Scott Chang

Moving A Database Application To SQL Server 2005 Express

Sep 13, 2006

I have been programming an application with VC++ 2005 and SQL Server 2005. I have converted an old 16-bit database to 32-bit managed code and SQL server and the application seems to be good. Now I want to deploy the application to another server for testing.

I have installed XP SP2, Windows Installer 3.1, Net framework 2.0 and SQL Server 2005 express to the test server. I have transferred the application with WI 3.1 and the program works well in the test server till the first SQL command. I have made a back up of the database and restored it in the test server. In the test server I can log in the database with Server Management studio and I can read the data there correctly. I have enabled both named pipes and TCP/IP for the database in the test server. With Surface Area Configuration I have enabled Local and Remote Connections Using both TCP/IP and named pipes. I only need Windows authentication at this time.

After all this when I come to the first SQL command in the application on the test server I receive the error message:
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).

My connection string to the database is:
'connection->ConnectionString = "Persist Security Info=False; Integrated Security =SSPI;"
"Data Source=TESTSERVER; Initial Catalog=TESTDATABASE;";'

When I use "Data Source=DevelopmentServer", the application works well on the development server.

Can't understand what is still wrong. Can you possibly have an answer for me?

Problem Migrating Application Database From SQL Server 2000 To Express Edition 2005

Jan 21, 2008

Hi there

I am new to SQL Server, but the current project that I am working on has the following requirement:-

1) Migrate the application (a servlet based web application on Apache Tomcat) from Solaris to Wintel
2) Migrate the supporting database from SQL Server 2000 to Sql Server 2005
3) Get IIS to communicate with Tomcat for serving servlet/jsp etc to the client

Though I successfully completed item 1 above, am stuck at item 2. Details are below

Actions taken for item 2

A. Installed MS 2005
B. Created new database in MS 2005 (logged in as user 'sa')
C. Generated SQL scripts (such as create table table_A etc) from existing MS 2000
D. Genearted SQL scripts (such as insert into table_A etc) from existing MS 2000
E. Created new schema in MS 2005
F. Ran scripts C & D in the new schema. All tables are records populated.
G. Obtained new JDBC driver and test run to see if connection is working fine, and it worked. Even ran an sql statment


Code Block[select count(*) from sa.table_A]

and got appropriate response.


H. When I made the application to talk to this new database (which is a copy of Production from step C, D above), it's behaving as though it cannot find the record.
I. When I further debugged, I realised that the web application is excuting queries without mentioning the schema. For eg.



Code Block[Select firstName, lastName from table_A]

Or rather it assumes that the user connecting to database is same as the schema name.


J. To further ascertain my point, I ran the query


Code Block[Select firstName, lastName from sa.table_A]

and it worked!



Now the real problem is that I cannot modify the existing code to append a schema name and this approach is rather not recommended best practise.


I tried to match the user name with the schema name, even made this schema as default to the user. But still not finding any luck.

I request all you experts out there to help me out with this problem.

Regards,

prad.nair

Can't Connect To Sql Server 2005 Database Using Vb 2005 Express

Nov 21, 2006

I've used Sql Server 2000 and Visual Studio 2003 for a few years. I've started a new position and they have access to Sql Server 2005 Standard and Visual Basic 2005 Express which I'd like to use for a new project. So I installed Sql Server 2005 and then VB 2005 Express on my workstation. I didn't choose the Sql Server option for VB Express because I already had Sql Server 2005 Standard installed with a simple database created. I created a simple vb project that justs connects to the database but I get the following error.


Request for the permission of type 'System.Data.SqlClient.SqlClientPermission, System.Data, Version=2.0000, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
I looked at permissions in the database and it looks ok. I'm the db owner and I'm using Windows Auth. My connection string is

"Data Source=MySystem;initial catalog=AdventureWorks;integrated security=true;"

I thought I'd look at the starter kit to get some ideas about what the problem is, but when I started the movie starter kit project, it was upset that I didn't have Sql Server 2005 EXPRESS installed. Yea, but I do have Sql Server 2005 Standard installed.
Any help will be greatly appreciated. Thanks.

Can't Connect To Sql Server 2005 From My Asp.net Application

Apr 3, 2006

Hi
I can't connect to sql server 2005 from my asp.net web page. I seem to be able to connect to it when i run the application from within visual studio but i can't connect to it when i run the application from IIS.I am new to sql server 2005 express so please bear with me.The error message i get is: Cannot open database "Vets" requested by the login. The login failed.Login failed for user 'OSCAR2K4ASPNET'.I don't know where this user OSCAR2K4ASPNET came from but i looked in sql server 2005 and there he is. In the left hand pane I went to Security and then logins and found oscar2k4asp.net there. I went to the properties for this user and went to User Mappings. There was no tick next to my Vets database so I added one and ran the application from IIS. I also added the user to every single role in the vets database (including dbowner). I also went into the vets database itself and found the oscar/aspnet user and made sure he was added to every role.
I ran the application again. This time i got a lots of different errors. If the page was trying to run a select procedure I got the error user does not have select permission. If the page was running an SP i got the error or user does not execute permission
I have never had this problem before so I don't understand.Where did this user come from? Was he created automatically when i configured my database for membership and roles? How do i set up this user so he can access the databsae from IIS.
The only way I could get the application to run from IIS was to go to Security - Logins for sql server and add the oscar2k4asp.net user to the sysadmin role.
I find this very strange. Naturally i don't want to leave oscar2k4 in sysadmin.
Please help :) I can't upload my website until i fix this
Thanks, andrea

Cannot Connect W/ Java App But Can Connect W/ .Net App - SQL Server Express 2005

Dec 12, 2006

I'm having a problem connecting with a Java application but I CAN connect using my .Net application - the user name and password are the same for both (using the same database on SQL Server Express 2005).

The error I get is: "com.microsoft.sqlserver.jdbc.SQLServerException: Cannot open database "CORNERS" requested by the login. The login failed." An interesing note - I get the same message if the database is not running.

SQL Server Express 2005 is installed in mixed mode.

Here is my connection string in the .Net appplication: <add key="connectString" value="Server=(local);UID=sa;PWD=myPasswd;Database=CORNERS" />.

These are my values in my Java app web.xml -

<init-param>
<param-name>DBDriver</param-name>
<param-value>com.microsoft.sqlserver.jdbc.SQLServerDriver</param-value>
</init-param>
<init-param>
<param-name>DBURL</param-name> <param-value>jdbc:sqlserver://localhostsqlexpress:1055;databaseName=CORNERS</param-value>
</init-param>
<init-param>
<param-name>DBUser</param-name>
<param-value>sa</param-value>
</init-param>
<init-param>
<param-name>DBPwd</param-name>
<param-value>myPasswd</param-value>
</init-param>.

And yes, the port is 1055 - I checked to find it.

I am using Microsoft SQL Server 2005 JDBC Driver 1.0 (sqljdbc_1.0.809.102).

Does anyone have any idea what is wrong so that the login fails in the Java application but works in the .Net application?

I Can No Longer Connect To My SQL Server Express 2005 From Manager Studio Express

Sep 28, 2006

Everything was working fine. I have been able to connect using windows authentication. Then, I went into the ODBC manager to add a data source and it failed to connect so I went back into the Server management studio to modify users. After doing this I now get an error when I try to conenct the management studio to the SQL server.

I wasn't modifying the login for my windows account that I normally use, I was modifying a different one, however I now get the message "An error has occured while establishing a connection to the SQL server. This kind of problem can ocure because the default behavior of the server does not support all connection methods" blah blah.

Does anyone know how I can attach to the server? Or, do I need to somehow remove the server and create a new one? How would I do that?

Thanks in advance for any input.

Can't Connect .Net Application From Windows Server 2003 To Database Server (SQL Server 2000)

Apr 3, 2008

Hi,
I am having a problem connecting my .net applications from the application server to the database server. When I run the application from my windows xp (sp2) box it works fine. When I try to connect via SQL Management Studio to the database server from the application server I get the same error.
Here is the error:
System.Data.SqlClient.SqlException: 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)
 Here is the Environment:
App Server:
Windows Server 2003 Standard Edition
Inside Company's Firewall/ Network
Database Server:
Windows Server 2000 Advanced Edition
SQL Server 2000 SP4
Remote Connections to the Server is checked
Enable Protocols: Named Pipes & TCP/IP
TCP/IP Port: 1402 (I don't know why it isn't the default of 1433)
The db server is sitting out side the Company's firewall (don't ask me why). I can access it fine from inside the firewall on my XP box but not from windows server 2003. There is a web server outside the our network that also connects to the db server with no problem and that is running Windows Server 2003 Web Edition.
I can ping the db server from the app server using the IP address.
I tried using the IP address and the port 1402 in my connection string but that didn't work from any machine (XP and Server).
I imagine the issue is somehow related to the company's firewall but why would it only block Windows Server 2003 and not XP?
What do I tell the network admin to change?
Any help would be appreciated.
Thanks,
Oran

Unable to open the physical file "C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDatacartracker.mdf". Operating system error 32: "32(error not found)".
An attempt to attach an auto-named database for file C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDatacartracker.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share.

I am using Visual Basic 2005 Express Edition along with SQL Server 2005 Express Edition.

Now here's what I did:

Rather than use the Database Explorer within VB2005 EE to create my database, I thought I would try creating my database externally using the downloadable "SQL Server Management Studio Express" tool. (I figured that if I had a stable data model for my database, I could side-step the copying/overwriting issues that come with creating a database as part of a VB solution.)

So having gotten my database setup and populated with some sample data, I am now trying to connect to it from Visual Basic. In VB (in the context of working on a VB Solution), I do the following:

Select Add New Data Source... from the Data menu to bring up the Data Source Configuration Wizard.
Choose "Database" for the data source type and click Next.
Click "New Connection..." to bring up the Add Connection dialogue.

For data source I choose "Microsoft SQL Server Database File", with ".NET Framework Data Provider..." as the data provider.
Navigate to my existing database file (in "C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLData" folder).
Use Windows Authentication.

When I click "Test Connection" or just click "OK", i get the Microsoft Visual Basic 2005 Express Edition error shown at the top of this message.

Is this occuring because I'm trying to access my database as an .MDF file rather than through Named Pipes / Shared Memory / TCP/IP? If this is the case, is there any way that I can tell VB2005 EE to use Named Pipes / Shared Memory / TCP/IP? Is this a fundamental limitation of VB2005 EE?

Thanks in advance to the guru who is able to explain this to me...

Hey all! I am new in this form and also new with the SQL serve. I have installed that free express edition of SQL server 2005 and when i am trying to connect to server from my C#.net application i am not able to do it and when i am trying to degug it gives me the error that is the user is not SQL thrusted user. I am able to connect directly thru SQL server using this userid and password but not thru VWD 2005 Express application.

using System.Data.SqlClient;

public partial class _Default : System.Web.UI.Page

{



protected void Page_Load(object sender, EventArgs e)

{

if (!Page.IsPostBack)

{

}

}
protected void Submit_Click(object sender, EventArgs e)

{

String querry;

SqlDataReader dbread;

try

{

SqlConnection conn = new SqlConnection(ConfigurationSettings.AppSettings["Conn1"]);

SqlCommand comm = new SqlCommand();

conn.Open();

querry = " Select password from login where userId='" + TxtUser.Text + "'";

comm.CommandText = querry;

comm.Connection = conn;

dbread = comm.ExecuteReader();

dbread = null;

if (dbread.HasRows)

{

while (dbread.Read())

{

if (dbread["password"].ToString() == Txtpwd.Text)

{

Response.Redirect("home.aspx");

Installing SQL Server 2005 Express As Part Of My Application

Jul 16, 2006

I have found a lot of info on MS site regarding installing SQL Server 2005 Express as part of an application. I have found these articles to be extremely inaccurate or at best incomplete.

1. The documentation says all I need is the setup.exe from SQLEXP but this is not true.

2. When I do launch setup.exe during my app's install, it fails because setup.exe trys to run the support.msi. Of course this causes failure because my install is also an msi.

So, does anyone know how to install SQLEXPRESS as part of my app's install?

Thanks.
