Can't Connect To Db Via Code, But Can From SQL Server.

Apr 10, 2004

Having an issue where I can connect to a remote SQL Database server via enterprise manager, however using the exact same db credentials, I can't connect via the .NET SqlConnection object...

Anyone have this error? Did you ever figure it out?

The error I get is: "SQL Server does not exist or access denied."

Again... I'm using the EXACT same user name, password, port number. I've setup an alias in Client Network Utility....

The SQL Server Enterprise is running on the exact same PC as the code I'm trying to execute.



Thanks for any help!

Cannot Connect To MSDE From C# Code

Dec 23, 2004

Hello everybody and happy holidays to all.
I'm new to C#, and I appologize for this basic question.
I am trying to connect to an SQL database from a very short C# program, which I found on the Microsoft site, demonstrating this subject.
Here is my setup:
Windows 2000 Professional
dotNET Framework 1.1 with sp1 installed
MSDE 2000
Note: I do not own nor do I have Visual Studio.NET of any kind installed.

Now, here is what works:
osql -E -S localhostvsdotnet
1>
And I can create and populate a database, which I called mydb.

Now, in my simple C# demo program I have this line

SqlConnection mycon = new SqlConnection("server=localhost;database=mydb;trusted_connection=true");

And the program compiles OK using "csc" command. But when I run it, I get this message:
Couldn't Open Connection to server=localhost;database=mydb;trusted_connection=true

Could anybody comment on what am I missing?
Thanks.

Connect To Sql Express 2005 Through Code

Feb 1, 2007

Hi All:

I'm new to using sql express 2005 as the database, so I apologize if my question is very basic.

I can connect to db through sql mngmt studio, but I don't know how to connect through application code. The authentication mode is windows. I'm having trouble with the provider in the application code.

Can someone please tell me where I can find more detailed information on available providers for sql express?

Thanks for any help, as I'm against a tight deadline.

Need Help With SqlConnection To Connect Table To A Variable In C# Code Behind

Jan 1, 2008

I need to connect to a table in my database to get the contents there to put into a string variable in C# behind code.   I’m having trouble with writing the part with the SqlConnection.   I want to take the contents from a specific field in a specific record.  I think the SELECT command might look like:SELECT formulation FROM Current WHERE id = 1formulation,id are fields, Current is the tableThe string variable is defined by: string test="000000";My connectionStrings in the web.config:     <connectionStrings>        <add name="ConnectionString" connectionString="Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|Database.mdf;Integrated Security=True;User Instance=True"            providerName="System.Data.SqlClient" />    </connectionStrings>

Help With Converting Code: VB Code In SQL Server 2000-&&>Visual Studio BI 2005

Jul 27, 2006

Hi all--I'm trying to convert a function which I inherited from a SQL Server 2000 DTS package to something usable in an SSIS package in SQL Server 2005. Given the original code here:
Function Main()
on error resume next
dim cn, i, rs, sSQL
Set cn = CreateObject("ADODB.Connection")
cn.Open "Provider=sqloledb;Server=<server_name>;Database=<db_name>;User ID=<sysadmin_user>;Password=<password>"
set rs = CreateObject("ADODB.Recordset")
set rs = DTSGlobalVariables("SQLstring").value

for i = 1 to rs.RecordCount
sSQL = rs.Fields(0).value
cn.Execute sSQL, , 128 'adExecuteNoRecords option for faster execution
rs.MoveNext
Next

Main = DTSTaskExecResult_Success

End Function

This code was originally programmed in the SQL Server ActiveX Task type in a DTS package designed to take an open-ended number of SQL statements generated by another task as input, then execute each SQL statement sequentially. Upon this code's success, move on to the next step. (Of course, there was no additional documentation with this code. :-)

Based on other postings, I attempted to push this code into a Visual Studio BI 2005 Script Task with the following change:

public Sub Main()

...

Dts.TaskResult = Dts.Results.Success

End Class

I get the following error when I attempt to compile this:

Error 30209: Option Strict On requires all variable declarations to have an 'As' clause.

I am new to Visual Basic, so I'm on a learning curve here. From what I know of this script:
- The variables here violate the new Option Strict On requirement in VS 2005 to declare what type of object your variable is supposed to use.

- I need to explicitly declare each object, unless I turn off the Option Strict On (which didn't seem recommended, based on what I read).

Given this statement:

dim cn, i, rs, sSQL

I'm looking at "i" as type Integer; rs and sSQL are open-ended arrays, but can't quite figure out how to read the code here:

Set cn = CreateObject("ADODB.Connection")

cn.Open "Provider=sqloledb;Server=<server_name>;Database=<db_name>;User ID=<sysadmin_user>;Password=<password>"

set rs = CreateObject("ADODB.Recordset")

This code seems to create an instance of a COM component, then pass provider information and create the recordset being passed in by the previous task, but am not sure whether this syntax is correct for VS 2005 or what data type declaration to make here. Any ideas/help on how to rewrite this code would be greatly appreciated!

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?

How To Show Description In Report Instead Of Code (Desc For Code Is In Master Table)

Mar 28, 2007

Dear Friends,



I am having 2 Tables.

Table 1: AddressBook
Fields --> User Name, Address, CountryCode



Table 2: Country
Fields --> Country Code, Country Name


Step 1 : I have created a Cube with these two tables using SSAS.



Step 2 : I have created a report in SSRS showing Address list.

The Column in the report are User Name, Address, Country Name



But I have no idea, how to convert this Country Code to Country name.

I am generating the report using the Layout tab. ( Data | Layout | Preview ) Report1.rdl [Design]



Anyone help me to solve this issue. Because, in our project most of the transaction tables have Code and Code description in master table. I need to convert all code into corresponding description in all my reports.




Thanks in advance.

Hello,
I'm using ASP.Net to update a table which include a lot of fields may be around 30 fields, I used stored procedure to update these fields. Unfortunatily I had to use a FormView to handle some TextBoxes and RadioButtonLists which are about 30 web controls.
I 've built and tested my stored procedure, and it worked successfully thru the SQL Builder.The problem I faced that I have to define the variable in the stored procedure and define it again the code behind againALTER PROCEDURE dbo.UpdateItems

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

SQL Server 2000 To SQL Server 2005 - Any Changes Required To Existing Code, System.Data.SqlClient.SqlConnection?

Dec 13, 2007

My web project (ASP.NET 2.0 / C#) runs against sql server 2000 and uses the System.Data.SqlClient.using System.Data.SqlClient;
 I use System.Data.SqlClient.SqlConnection and System.Data.SqlClient.SqlCommand to make the connections to the database and do selects and updates.  Is it correct to continue to use these against SQL Server 2005?  I ask because I made a connection string (outside of .Net) for SqlServer 2005 using the SQL native provider and it had the following - Provider=SQLNCLI.1 and any connection strings I had made (also outside of ASP.NET) fro SQL Server all used Provider=SQLOLEDB.1.  This is why I wondered if there is a different SqlClient in .Net 2.0 for SQL Server 2005?
Cheers

I designed the AlwaysOn wrong, but every time we fail over from primary server to another server, my applications cannot connect because the sql logins cannot connect to their default databases. Once I run the command to link the login with the user in the default database then the users are able to connect. Did I do something wrong when designing AlwaysOn?

SQL Server Express Code On MSDE/SQL Server 2000

Jun 21, 2005

hi - I am developing locally using .Net 2.0/Access but just recently started trying out SQL Server Express. I have deployed my application to a host who provides 2.0 but as would be expected only MSDE/SQL server 2000. Now if I'd switch completely to SSE, would my SQL queries (which are pretty simple) work on MSDE or SQL server 2000? The only thing I see as more sophisticated sql queries would be the built-in 2.0 Roles/Membership functions... Do you think they would run smoothly on MSDE/SQL 2000?Finally... since the database is already done locally, is there any way (a stored procedure for example) to copy it's scheme if I'd create a new DB on my host's SQL server?

When i use the same query at microsoft access to the same database it works fine but not in visual web developer (language: C#).



I have no idea what's the problem here, please help me!

How Do I Connect Client Machines To SQL Server 2005 Installed On A Windows 2003 Server

Apr 11, 2008

I am new to SQL server 2005


Windows 2003 Server and all client PCs are all on the same network. I installed SQL 2005 std version on windows server 2003 and created a database and tables in it.

I have two users, who want to connect to SQL server 2005 from their PCs (they have windows XP):

These are two things that I need to facilitate:

1) They want to be able to write queries using Query Designer and run from their PCs.

2) I created an MS Access database on my PC, I want to use Access database as a front end to the SQL server database. I will create queries, forms in Access DB, and I want to be able to get the data from SQL server Database to do this. I guess I can use ODBC to connect to tables in SQL server database.

3) I want to connect SQL server to Oracle database, and run oracle stored procedures. I want to load the results of oracle stored procedures into SQL server database tables. I guess I will use IIS for this.

Any suggestions are appreciated, especially with item number 1.

The user LMSEndPointUsers is a SQL Server Login
The user ostc-dev-001endPointUsers is a machine login

We have employed the Security class as per the information given in the SQL Server documentation with the intention of using the WS-Security headers that apparently are to be used when trying to authenticate using a SQL Server login.

----------------------------------------------------------------------------------------------------------------

Code used to connect and try and reciev the dataset.


string sUserName = "userName";

string sPassword = "Password";



LMS_Endpoint.OSTC_LMS_Endpoint wsSQLTester = new LMS_Endpoint.OSTC_LMS_Endpoint();

SqlSoapHeader.Security sqlSec = new SqlSoapHeader.Security();

sqlSec.Username = sUserName;

sqlSec.Password = sPassword;

XmlWriter writer = XmlWriter.Create("Security.xml");

writer.WriteStartElement("security");

sqlSec.WriteXml(writer);

wsSQLTester.sqlSecurity = sqlSec;


DataSet dsMySet = wsSQLTester.ostc_SQLSoapTester("RH6915145507");


Basically authorization is denied 401.
Hope someone can help here as have tearing my hair out.

Thanks in advance

SQL Server Management Studio Cannot Connect To Local Instance Of SQL Server 2005 SP2

Aug 8, 2007

Hello,

I just installed SQL Server 2005 Enterprise edition from my company's DVD. It was installed with the setting of using both Integrated windows authenitication as well as basic named authenication. I installed all the options too: Database Engine, Analysis Services, Reporting Services, SQL Server compact edition, and Integration Services. When I look at services there are: SQL Server Integration Services, SQL Server Analysis Services, SQL Server Reporting Services, and SQL Server Browser. All of which are running. Something that took me offguard was the installation did not ask me to provide an SA password. Other than that, the install looked like it went good.

I was able to connect to the local instance of the SQL Server 2005 using the SQL Server Management Studio. I could connect with SA, or connect with Integrated Windows Authenication. Whoohoo. Off and running! As a matter of fact, for the SA account I could use any password and it would still log me in.

First thing I did was I went in to the copy wizard to attempt to copy a database from a server on our network to my local box. First it asked me for the remote server. Then when I specified my local instance in the wizard, the wizard complained that my local instance was NOT SQL Server 2005. Doh! This I didn't understand. I figured maybe I need to check for MS updates. Sure enough, I found that ther was a SP2 and then a hot-fix for that SP2. I applied both. Now I cannot connect from SQL Server Management studio to my local instance of SQL Server 2005 database server. I get the following error:

"An error 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) (Microsoft SQL Server, Error: 2)"

However, I went in to see what other services I could connect to, and here's the results:

Analysis Services : OK!
Reporting Services (Windows Auth/Basic/Forms) : NG "The reporting Services Instance could not be found (Microsoft.SqlServer.Management.UI.RSClient)"
SQL Server Compact Edition : NG "The database cannot be found. Check the path to the database. [ File Name = CCG092 ] (SQL Server Compact Edition ADO.NET Data Provider)
Integration Services : OK!

I can connect to other SQL Server databases on our network. However, just not my local one. No one on the network can connect to me either.

I even turned off my windows firewall and still no luck connecting to my own.

So something really went wrong when I applied SP2, however, admittedly from the error message when I tried to use the copy wizard, something was probably already wrong.

Any ideas?

Thanks!

SQL Server CODE Pages

Jul 6, 1999

Does anyone know a workaround for the code page translation that occurs if you use bcp to
transfer data in and out of SQL Server. I have a table that I am losing certain characters in the
transfers.

SQL Server 7.0 has the -C code page specifier added to BCP to address this but I am running 6.5 currently.

Any ideas on how to deal with this?

Thanks,
Phil

Can't Connect To Local Server Instance MSSQLSERVER In SQL Server Management Studio (SQL2005 Sp2/Vista)

Apr 7, 2007

Can't connect to local server instance MSSQLSERVER in SQL Server Management Studio (SQL2005 sp2/Vista).



SQL Server Configuration Manager reports SQL Server2005 services: SQL Server (MSSQLSERVER) Running. This would indicate the name of the SQL server is "MSSQLSERVER" correct? I chose "default" instance during the install and that is the name it gave itself.

I tried connecting to the server using the following for the Server Name: MSSQLSERVER and .MSSQLSERVER neither works.



The only thing that works for my installation is just plain "." (no quotes) and nothing else. Can this be correct because I can't find any reference to this. Thanks.
