Dynamic OLE DB Connection String With Static User ID And Password

Apr 30, 2008

I'm trying to setup a dynamic ole db connection using the SA user ID, it has to be dynamic because the server name will change and it has to be SA because we're pulling information from system databases that some users don't have access to.

If I setup a regular static connection using SA credentials it works like a charm of course. When I create an expression to use the User:erver variable it doesn't work, it throws an error message saying that "The login failed for user sa" among other things, I'm thiking that the sa's password is not being saved.

Where exactly do I place a password for dynamic connections using sql server users? On the connection string? On the password property of the source? Any ideas?

Dynamic Connection String

Mar 2, 2007

Our Reporting Services environment uses Oracle as the data source. Based upon the user connecting to the database determines what rows they will see for various tables. How can we dynamically pass the username/password to the connection string? Background: Our users log into Active Directory and are assigned to a group. The AD group name is used to access a control table in Oracle that contains the database username/password for that group€™s connection to Oracle. All subsequent connections to Oracle will use the group€™s username/password from the control table. We have an ASP.NET application that works like this and stores the connection information in the session state. How can we do something similar with our connection in Reporting Services? Note: Our Oracle Database does not use Windows Integration.

How To Use ProviderName, User ID, Password, And Connection Saved In Web.config And SqlDataSource

Jun 1, 2008

Just downloaded and installed the VS 2008 Express and created/tested some websites.   I have done several aspx websites using VS 2005 during the last 2 years.  Still I don't quite understand the details of coding the database connection and DataBing.  For example, what does 'providerName',and Integrated Security really mean?Why in the Web.config file these are providerName="System.Data.SqlClient" and Integrated Security=True?  Why in Default.aspxthere are both ntegrated Security=True;and USER ID=WEB; Password=webwebweb1".  I know these may deal with the authentication mode of my SQL Serverdatabase.For the VS 2008 Express and SQL Server 2005 Express, I installed in my XP home PC, I used the file system websites,  If I upgrade to XP Pro and install IIS web server, and use SQL Server 2005, what might be different? Jeffrey Web.config <connectionStrings>        <add name="NorthwindConnectionString" connectionString="Data Source=D5MRY6G1SQLExpress;Initial Catalog=Northwind;Integrated Security=True"            providerName="System.Data.SqlClient" />    </connectionStrings>Default.aspx <asp:SqlDataSource ID="SqlDataSource1" runat="server"         ConnectionString="Data Source=D5MRY6G1SQLExpress;Initial Catalog=Northwind;Integrated Security=True; USER ID=WEB; Password=webwebweb1"         ProviderName="<%$ ConnectionStrings:NorthwindConnectionString.ProviderName %>"MasterDetail.aspx <asp:SqlDataSource ID="SqlDataSource2" runat="server"         ConnectionString="<%$ ConnectionStrings:NorthwindConnectionString %>"

Dynamic Connection String Problem

Mar 1, 2007

I need to be able to deploy my updated website to many customers on a monthly basis and dont want to be mucking around changing the connection strings each time. Some of my web servers have multiple copies of my site and DB so each website will need a different connection string.
The simplest method I could come up with is to use the Application Name field in IIS as it doesn't get overwritten by Visual Studio when I deploy the site.
I am trying to write some code to dynamically change the connection string in the web config but cannot find any way of reading the Application Name field in IIS to use in altering the connection string. I'm using the Global.asax file to change the connection string before the DB gets called.
I had tried embedding the DB in the website folder but it would overwrite the customers database.

Dynamic Connection String For Oracle

Oct 31, 2007

i have successfully implemented a dynamic connection string based on a dropdown list of environments (dev, test, prod). it works well during testing in the vs2005 ide; but once i deploy it to the rs server, it complains that the credentials are not stored in the rs server database and won't run the report.

as in most large organizations, the developers do not have control over the rs server, so i cannot manipulate rs config or web config files on the server side; so, how do i get past this obstacle?

thanks in advance

HELP - Cannot Use Dynamic Connection String With Excel?

Aug 23, 2007

This method has worked beautifully for all my SSIS pkgs thus far.

Basically, I use a Script Task to derive the name of the newest file in a local directory. Then I save the name of the file to user a user variable, e.g. User::File.

Then, in my flat file properties > Expressions, I set "ConnectionString" to reference User::File.

However, when attempting to use this method with an Excel source, I get this error message:

Error at myPkg [Connection manager "Excel Connection Manager"]: The connection string format is not valid. It must consist of one or more components of the form X=Y, separated by semicolons. This error occurs when a connection string with zero components is set on database connection manager.
Error at myPkg: The result of the expression "@[User::Folder]+ @[User::File]" on property "ConnectionString" cannot be written to the property. The expression was evaluated, but cannot be set on the property.


HELP......... I need this to work!

Thanks

Dynamic Connection String For Analysis Services

Jun 29, 2006

I have a package where I need a dynamic connection string for an Analysis Services connection manager.

I have implemented this successfully for a Text data source, and a SQL data source, but the same approach does not seem to be working for an AS connection.

I set some expressions for the AS connection manager (ServerName, InitialCatalog, even the entire ConnectionString itself), but they don't take. I don't get any errors, but the task processes the cubes for the AS connection as it was established at run time. The design time connection string changes don't appear to get evaluated. This seems to be an issue only for AS connections.

Let me know if you have any ideas - thanks.

Dynamic Connection String Problem In SSRS2005

May 7, 2007

Hi, I'm a newbie to SSRS, and was wondering if anybody can shed light on a problem I have. I have a report which every client uses, but each client's data is held in its own database. Rather than create many reports, is it possible to create 1 report, which all can use, passing in the different datasource? I was thinking of a hidden parameter, passed by URL. Or maybe using the report viewer control in VS2005. Can anybody please help?

Thanks

Reporting Service-Dynamic Connection String &&amp; Multiple Instances

Oct 1, 2007

I am facing a reporting service issue.

System information:
1. Our Reporting Server installed on a DB server.
2. We have one windows application which executes on the same server, which generates the reports snapshots.
3. One set of reports with single Shared data source

Scenario:
We have many countries for which report history snapshots needs to be generated. The report information is stored in different databases named as database_CountryCode on the same DB server.

Questions:
1. We need to dynamically change the shared data source connection string to point to the respective country database, when generating the report for that particular country. --> We found out this can be accomplised by using parameterized connection string in report specific data sources in SQL 2005. Can we achive something similar in SQL 2003 Reports as well?
2. We also need to instantiate the reporting service web service in multiple threads, one for each country, where in each thread picks up the corresponding country code, changes the connection string and generates reports snapshots. Can this be accomplished? I know this goes against the entire idea of licensing, but my question is just about feasibility of this idea.

Addnl Info
The CreateReportHistorySnapshot method of reportingservice.asmx returns a snapshotID, which is the timestamp of report snapshot creation. We tried creating the same report snapshot for the same country in 2 threads. Whenever the timestamp for both snapshots was same, only one report snapshot actually got created. Can this be overcome?

SSIS-problems Making A Dynamic Flat File Connection String

May 8, 2007

Hello.

I have packages that must generate log errors dynamically including time of execution and the name of the task.

I make it changing the properties of the connection inserting two expressions.

1.-I alter the File Usage Type to 1 to generate this files.
2.- I alter the connection string as: @[User::myvariable] +"constant_description"+ time description+ +".txt"

The time description is :
(DT_STR,40,1252) DAY (GETDATE())+"-"+(DT_STR,40,1252) MONTH( GETDATE())+"-"+(DT_STR,40,1252) YEAR( GETDATE())+" + REPLACE( (DT_STR,10,1252) (DT_DBTIME) GETDATE(),":","_")
But it is not the problem

In those packages I have one connector for all the tasks and in execution time it creates one file for each of the tasks.

The problem is the way I insert in the filename the task name.

I have a pre-execute event handler in each task that modifies a string variable( myvariable) appending the task name. When I execute de package it works great but when I only execute a task, the program do not enter in the event and do not put the task’s name.

How can I put that name without using that handler? There is another handler can I use to do it that happens before the system generates the new file name and after pre-execute? Anyone knows another way to do this kind of things?

What Is Better.. Static Or Dynamic Memory Allocation ?

Keeping Dynamic DateTime Variable Static

Apr 28, 2007

In one step of an SSIS package, i create an outgoing XLS filename based on the current datetime setting, a la:



"myFileName_" + (DT_WSTR,4)YEAR( getdate()) + RIGHT("0" + (DT_WSTR,2)MONTH( getdate()),2)+
RIGHT("0" + (DT_WSTR,2)DAY( getdate()),2) +
RIGHT("0" + (DT_WSTR,2)DATEPART("hh", getdate()),2) +
RIGHT("0" + (DT_WSTR,2)DATEPART("mi", getdate()),2) +
RIGHT("0" + (DT_WSTR,2)DATEPART("ss", getdate()),2) +".xls"



which provides the format as myFileName_yyyymmddhhmmss.xls.



This value is then assigned to a variable, user::myFilenameDateTime.



This variable is referred to in various steps which need the full pathname or filename.



I found, though, that in subsequent steps, the value for user::myFilenameDateTime is re-calculated whenever the variable is invoked.



So in one Task i created the physical output XLS file and named it "correctly", eg, myFileName_20070428090204.xls; in the next Task, i call a Stored Procedure in SQL Server 2005 to email the file with a corresponding message (that pulls in more data from the database).



The single Parameter to the Stored Procedure (that does the emailing) is the supposed/expected full Pathname of the outgoing file just produced but the parameter no longer represents the original filename -- and has changed slightly (a few seconds have been added) and the filename is now, myFileName_20070428090210.xls; consequently, my Email Distribution program cannot find the file with that specific name, although File = myFilename_20070428090204.xls does certainly exist.



so it appears that these variables are calculated realtime whenever encountered.



1) Am I misunderstanding something or misusing the variable assignment?

2) How can i keep << myFileName_yyyymmddhhmmss.xls >>, "static" throughout the duration of the overal SSIS Process.

3) I would think that even if I assign the derived myFileName value initially to ANOTHER "static" variable, this won't achieve anything because the new variable will be re-calculated again, as well, when it is invoked.



thx/spirits,



seth j hersh

Hi.  New to ASP.NET and first time posting.
My web app connects to a SQL database - SQL authentication. 
Users login to the web app through the login server control.  Once authenticated, it is my understanding that the user name and password are stored on the client as a cookie. 
How do you programmatically get this user info and use it for the userid and password parameters of the connection string?
Is there a better way to use the authenticated user info to access a SQL database?
