Hi, guys. It's the first time I connect a database.
My OS is windows XP.
I downloaded the sqljdbc on microsoft website and unzipped it.
Copy the sqljdbc_1.1 to the directory C:Program Files.
Modified the system variables:
classpath=.;%JAVA_HOME%libdt.jar;%JAVA_HOME%lib ools.jar;
%ProgramFiles%sqljdbc_1.1chssqljdbc.jar
JAVA_HOME=D:Program FilesJavajdk1.5.0_10
ProgramFiles=C:Program Files
I installed the sqlserver 2005and created a sqlserver db engine with windows authentification by default.
Using the management studio I created a database named BudgetAuthorization.
After that I created a user:
CREATE LOGIN aaron792 WITH PASSWORD='12345'
USE BudgetAuthorization
CREATE USER aaron792
Now I want to write a java application to access the database.
The application and the database are on the same computer.
I started the TCP/IP service, using the configuration manager.
Then use the eclipse to write the java application:
import java.sql.*;
public class TestJDBC
{
public static void main(String[] srg)
{
String driverName
= "com.microsoft.sqlserver.jdbc.SQLServerDriver"; // Start JDBC
String dbURL = "jdbcqlserver://localhost:1433;
DatabaseName=BudgetAuthorization"; // Connect the server and the database
//String userName = "Administrator"; // windows user
//String userPwd = "password"; // windows login password
String userName="aaron792";
String userPwd="12345";
Connection dbConn;
try
{
Class.forName(driverName);
dbConn = DriverManager.getConnection(dbURL,userName,userPwd);
System.out.println("Connection Successful!");
// if successful print Connection Successful!
}
catch (Exception e)
{
e.printStackTrace();
}
}
}
But it cann't be done!
The error information is：
Login failed for user 'aaron792'. The user is not associated with a trusted SQL Server connection.
I also tried the windows user, still failed.
What's wrong? Can anyone help?
Many thanks!

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 have just upgraded to Microsoft SQL Server 2005 Express Edition with Advanced Services SP2.
Now I can't connect to my local database.mdf file.
When trying to open or doubleclick or expand my .mdf file the following message pops up:
Generating user instances in SQL Server is disabled. Use sp_configure 'user instance enabled' to generate user instances.
What is the solution for this problem?

Unfortunately I was sent to this product by my Hosting Site since all I was trying to do was Create and Manage a User Login with authentication to my subsites in MS Frontpage. (rant: Why doesn't Frontpage support this technology???)
Anyway, I have now spent (wasted?) 8 hours downloading, installing, and tyring to configure SQL Express along with MS Visual Web Developer Express for ASP.NET 2.0 ... For the life of me I can't find detailed configuration informatin and setup information to build a SIMPLE database to connect to the VW product. Folk: this HAS to be simpler to do than what you present in the product! This is way too difficult to deal with compare with frontpage.
Is there a simple "how to" link someplace that is specific enough to preclude me from uninstalling this entire suite ????

Hi,
I am a beginner on using SQL Server Express. I have two different questions. Here is the first:
I've developed a simple C# application in Visual Studio 2005 that connects to a SQL Server database file. In the application I connect to the database using this connection string:
@"Data Source=.SQLEXPRESS;AttachDbFilename=C:Databasesmydatabas.mdf ;Integrated Security=True;Connect Timeout=30;User Instance=True";
and It works perfect.
But when I move the database file(and the corresponding log-file) to another computer it fails. I've changed the connection string to this
@"Data Source=.SQLEXPRESS;AttachDbFilename=\myserverDatabasesmydatabase.mdf ;Integrated Security=True;Connect Timeout=30;User Instance=True";
This is the error message I get when I try to open the database
The file \myserverDatabasesmyDatabase.mdf is on a network path that is not supported for database files.An attempt to attach an auto-named database for file \myServerDatabasesmyDatabase.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share.
Both computer runs Windows XP SP2.
My second question is:
When I deployed my solution to my production PC(witch also runs Windows XP SP2, .NET Framwork 2.0 is installed on the computer) .When I then tried to run the application I did get this error message
An error has occured when establishing a connection to the server. When connection to a SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remomte conections.....
Appearently I cant treat SQL Server database files in the same way as Access-files, or?

I recently created a program that connects to a Microsoft SQL database that was stored on my computer and it worked fine. As soon as I tried to connect to the same database via a network drive I got an error stating that "The file Y:Filename.mdf is on a network path that is not supported for database files.". I can't seem to get it to work, if anybody has any ideas what I'm doing wrong I would appreciate your help.

Hello Everyone,
I am new to connecting to databases through java and in fact have not done much database programming although I am fairly good at SQL.
I have used the MS JDBC driver to connect to a MS SQL server database but I want to update my application every time a record is added to the database and or alert the user.
From what I have read, i assume that I can create a Trigger in java but how do I get my trigger to call a method / run java code?
Thanks for your time and Help
Martin.

Hey All,
I am having a problem connecting to a database I have with a java app I am creating for my senior project. I am using the latest MS JDBC for connecting to the SQL Server.
Below is the code I am trying to run:
try {
ds.setIntegratedSecurity(true);
ds.setServerName("localhost\SQLEXPRESS");
ds.setDatabaseName("*databasename*");
con =ds.getConnection();
} catch (Exception ex) {
ex.printStackTrace();
}
The ds and con variables are declared and initialized correctly. The error I am getting now is this:
com.microsoft.sqlserver.jdbc.SQLServerException: Cannot open database "*databasename*" requested by the login. The login failed.
Any suggestions on what I could be doing wrong?

Greetings, I have just arrived back into the country (NZ) and back into ASP.NET.
I am having trouble with the following:An attempt to attach an auto-named database for file (file location).../Database.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share.
It has only begun since i decided i wanted to use IIS, I realise VWD comes with its own localhost, but since it is only temporary, i wanted a permanent shortcut on my desktop to link to my intranet page.
Anyone have any ideas why i am getting the above error? have searched many places on the internet and not getting any closer.
Cheers ~ J

hello,
I have a question about opening files in the Microsoft SQL Server 2005 Management Studio.
In the old Query Analyzer from SQL 2000 I can open SQL Files via drag & drop (from explorer to QA) or open it with a double click in the explorer. Then the Files opened, if I had actual a connection to a server / database (QA is stared with one file and has a connection to Server/Datebase), with this connection.
Now in Microsoft SQL Server 2005 Management Studio I'll be asked everytime for Server and have to get the database from the database list - it does not connect automaticly to server/database, that is actual connected (I have opened a file with the connection and a connected database in the object explorer).
Someone do not have this problem - but we found no option to set it up.
Any ideas?
thanks &
best regards,
Christian Kiedels

I know allot of folks are having this problem and I tried lots of things but nothing works. I understand the problem is coping the SQL Express on another server is the problem - I just not sure what to do?
Version Information: Microsoft .NET Framework Version:2.0.50727.42; ASP.NET Version:2.0.50727.42
This is the last statement on the Stack Trace:
SqlException (0x80131904): An attempt to attach an auto-named database for file e:wwwdata81d0493fwwwApp_DataTestDatabase.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share.]
System.Data.SqlClient.SqlInternalConnection.OnError(SqlException exception, Boolean breakConnection) +735091
I checked my server forum and they said I had to name a database:
Example: Database=(unique name);
But this didn't work either.
I just tried a simple web project that has only one database and one table in SQL Express with one sqldatasource and one datagrid. It works fine on my pc but when I use the copy function in Visio Studio 2005 Pro - I can't run the site on the remote server: www.myjewelrydirect.com
I tried coping the database manually. I tried disconnecting the database before I copy it. Below is my connection statement:
<connectionStrings>
<add name="TestDB" connectionString="Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|TestDatabase.mdf;Integrated Security=True;User Instance=True"
providerName="System.Data.SqlClient" />
</connectionStrings>
With all the comments in these forums - this must be a bug.
I have been working on this problem for over 2 weeks - HELP!

Can anyone please teach me how to make a connection between jsp file and Microsoft SQL Server database steps by steps?
I'm using Windows XP and I found that my computer do not have JDBC (I already have ODBC). Is this mean that I have to install some JDBC or SQL driver in order to make the connection? Which driver should I install and where can I get the driver?
If possible, please show me some example so that I can understand better..Thanks a lot.

I have an application that creates a new database during installation,and I've noticed some strange behavior. Once I've created thedatabase, I am able to immediately create tables and populate lookupdata, provided I remain connected to the server. If, however, Idisconnect and attempt to reconnect immediately, I'll get an errorsaying that my login is invalid for the new database.I can get around this by having my code simply wait 5 seconds beforeattempting to reconnect, but I'm curious to see if anybody here cangive an explaination for why this is happening. Here is a bit ofpseudo code to explain what I'm seeing:open new connectioncreate databasecreate tablespopulate tablesclose connection// open new connection /* can't do this yet, as it would break */for (int a=0; a<5; a++){Thread.Sleep(2000)try{open new connectionbreak;}catch{Debug("still waiting...");}}Running my version of this code, I'll see that "still waiting..."message go past 2-3 times before SQL Server wakes up and realizes thatI'm allowed to connect to it. Anybody know why?Thanks,Jason KesterExpat Software Consulting Serviceshttp://www.expatsoftware.com/---Get your own Travel Blog, with itinerary maps and photos!http://www.blogabond.com/

:eek:
I want to use the Office Web Components (v10) PivotTable embedded in a web page. The examples and tutorials I've been able to find on MSDN all use the same architecture: The initial pivottable configuration is created by instantiating the object server-side and programmatically configuring it. The XMLDATA property is then read and sent to the client. At the client, script sets the XMLDATA property. So far so good, all makes sense. Then my problem: The PivotTable is then connected to Analysis Server using an http connection string (through IIS). As my users do not have database accounts, only application accounts, I cannot allow database connection information on the client. Trouble is, the PivotTable generates MDX queries when a user reconfigures the view, and there are no hooks (events or other means) to programmatically obtain the generated MDX query - a fact that is explicitly confirmed in MSDN documentation.
This clearly means that the PT must be connected directly to it's data source. So I thought I could just create a local MOLAP cube file and download it to the client (permissible as it runs as a trusted application). But nowhere can I find any example or documention on how to do this.
This is driving me slightly insane and I have little hair left now; if anyone knows how to do it or where to find proper PivotTable documentation (rather than a collection of examples that do something else from what I need to do!) then help is greatly :p appreciated!

All --
Please help.
Is it possible to connect to MDF file without having SQL Server 2005 Express installed on the machine?
That is-- can one connect directly to an MDF in the same way and Access MDB file can be used?
If no, then is there any way around this?
If yes, then are there any limitations?
Please advise.
Thank you.

My preferred programming language is Java (sorry Microsoft). I've searched for examples of running DMX queries into an Analysis Services database from Java but failed to locate any. I've seen suggestions that XMLA could be used but again, I can't locate any examples (in any language). For my current project I ran up the white flag and used C# instead but this wouldn't be an option in other cases. It would be possible to make the DMX calls from C# objects and call those from Java but that's pretty labourious to code.
Suggestions?

I have a very simply package using an Excel connection to an XLSX file. It's a straight read of the file and import onto a table.
The package works fine in Visual Studio 2008 development and also runs fine when executing on the (server I copied it to) under Integration Services.
However, under a SQL Agent, the package (32-bit is checked) can not acquire the connection to an excel file. I use UNC pathing to the file. I've read other posts about similar problems and tried various scheduling options (including Owner of job).
I even tried a to trigger it with a command-line which did not work:
"C:Program Files (x86)Microsoft SQL Server100DTSBinnDTEXEC.exe" /sq "our packagesMy_XLSX_File_Import" /SERVER myserver /X86 /CHECKPOINTING OFF /REPORTING E
All errors are: "DTS_E_CANNOTACQUIRECONNECTIONFROMCONNECTIONMANAGER. The AcquireConnection method call to the connection manager "Excel Connection Manager" failed with error code 0xC0209302."

Anyone have any tips for using Java against SQL Server? Our ITdirector is thinking of making us a Java shop, but I really would liketo stay with SQL Server as our RDBMS. We have Oracle Financials butour in-house development (currently VB6 client-server, soon to bereplaced by a service-oriented architecture based around Sonic andincluding SalesForce, both of which are Java) has been against SQLServer. He says five years ago at his old company Java/SQL Server hadlousy performance. I vaguely remember that since then Microsoft cameout with their own JDBC driver for SQL Server... Anyone have experiencewith this? Any performance tips will be hugely appreciated.TIA
