I have created a connection in connection manager.
using expressions i have declared a connection string
"Data Source=" + @[User::servername] + ";Initial Catalog=" + @[User::catalog] + ";Provider=SQLNCLI.1;
Integrated Security=SSPI;
Auto Translate=False;"
when i click 'evaluate expression ' it just displays
Data Source=;Initial Catalog=;Provider=SQLNCLI.1;
Integrated Security=SSPI;
any anyon etell me if iam doing any mistake
I am trying to connect to multiple data sources of same type say (sql) pn different servers and run the same data flow task on all of them.
what i need to acomplish is make the connection dynamic, i tryed the sample flat file connection and i understand that i have to
1, declare a variable 'connectionstr'
2, in the connection manager properties > expression property i have to select connection string and exeression as @[user::connectionstr']
then i am out of thoughts i know i must use FOR loop but how
even FOR loop has expression, enumerator.....
how would i point the connection string variable to a list of values(srvrname,databasename, tblname) stored in a table.
Thanks in advance...

Hi,
SSIS packages are now created and tested against dev sql server.
Now I would like them all to point to the live sql server.
What is the best way to have the connection dynamic?
Obviously I prefer not to go through each package and change the connection manager.
Thanks
Hi All,

Hi,
I am looking to allow a user to select which database they need to connect to, and then for them to be able to use that connection string until they choose a different database. I have a separate database specifically to hold the list of databases with the respective connection strings, and various forms that are currently looking at the web.config for the connection string. Unfortunately, I can't just put all the connection strings into the web.config as the number of databases available to the user will increase on a weekly basis which will be handled by a database administrator, so I want a user to select from a list of databases (for which they have permissions), and for that connection string to remain for that user. Potentially there will be 20 or more users each connected to a different database (all SQL Express).
If anyone can provide any help on this I will be truly thankful as I've hunted on the internet for hours and have been unable to find anything that has helped.
Thanks in advance.

Dynamic connection strings
I have found lots of people asking for something similar to this but cannot find any solutions - can you help?
I am developing an application (ASP.Net2) in which users are associated with 'Clients' and every Client has their own SQL Server database.
Users are authenticated using standard ASP.Net Authentication via a separate database (common for all users). This includes a table linking them to a Client and each Client record includes the connection string to their database. Currently a default connection string is held in the web.config file.
My problem is that I don't know how to dynamically change the connection string after a user has logged on. I have a large number of databound controls, many of which are declared and some are coded in the VB.Net code behind. I know I can use code behind to change the connection string for a SQLDatatSource:
I thought I had it cracked with the following:
Public objClientConnection As New ConnectionStringSettings
Public Sub Page_Init(ByVal sender As Object, ByVal e As System.EventArgs)If Session("ClientDBConnectionString") <> "" ThenobjClientConnection.ConnectionString = Session("ClientDBConnectionString")objClientConnection.Name = "ClientDBConnection"objClientConnection.ProviderName = "System.Data.SqlClient"ElseobjClientConnection = ConfigurationManager.ConnectionStrings("WebTool1ConnectionString")End IfEnd Sub
The session variable Session("ClientDBConnectionString") holds the client specific connection string and is populated when the user logs on. If this is not populated then the connection string defaults to one collected from web.config. This should ensure there is always a design time connection string available.
The trouble is, when I try and declare the SQL data souce like this:
<asp:SqlDataSource ID="dsTest" runat="server" ConnectionString="<%# objClientConnection.ConnectionString %>" SelectCommand="usp_SEL_DocumentTypes" SelectCommandType="StoredProcedure" ></asp:SqlDataSource>
I get an error: The ConnectionString property has not been initialized.
I have been going around in circles on this for days and would really appreciate some help. Am I on the right lines? What needs to change to make it work? Is there a better way?
Many thanks,
Cliff
Hi,
i want to modify my DTS to don't have any maintenance to do on it if a Username or password change.
Each DTS will have an ActiveX script to read connections properties in a table that i created and will automatically set each connection in the DTS each time that the DTS Run. So, we will have only to update the table and the DTS will continue working fine.
To update the Connections properties i have no problem, the problem is how can i retrieve the data from my table to get the connection properties, without hardcoding a connection inside my ActiveX script? Because i don't want to have to change each ActiveX script in each DTS if the SQL Server paswword change.
Any idea will be appreciated
Thank

We were able to use a dynamic connection string in the report designer, but once we deployed to the report server we are getting the following error:
Error during processing of the ConnectString expression of datasource €˜Dynam€™. Has anyone experienced this, and how did you fix it?
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.

View 7 Replies View RelatedI 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.
Hi,
In c# - how to pass uid,pwd,dbname and servername as input parameters from vs 2003 windows application (am calling the rdl file from reporting service 2005 web service) to sql server 2005 rdl files.

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
Hi,
Is there any way to Dynamically change(Based on User login) Connection String for a report data source from code behind. In My application each user may have different data base. I am using a single shared data source for all the report. Please give me a solution.
Thanks

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
I am trying to split a .csv file on a week+location key. As there are 500+ locations and 52 weeks in a year this is not a manual task.
I have a Script component written but need to dynamically open/close the connection manager changing the connection string in between, to the Week+location key as the filename.
It has to be do-able because the ForEachLoop does it. But how do I?
Hi There
This should be an easy one i hope.
I need to dynamically change the file name of my destination flat file connection everytime the package runs, obviously i do not want to edit the config file everytime.
I think the best way to do this is by a script taks that sets the connection manager filename property with a variable that i dynamically populate.
Is this the right way?
I just want to be sure that there is not an easier or better way to do this?
Thanx
Hi,
in my actual szenario I have to change the Server (Connection String) of Analysis Services Connection Manager from my testserver SERVER1 to my production server SERVER2. Nearly everything is easy...I set a variable to the correct servername and I used a expression to change the connection string of the connection manager during run-time. I used this technic serveral time with ole db and it works fine.
Debugging of the project shows that the variable is set correctly. The delay validation flag is set to true. When I run the package the connection establish a connection to the server which I use due designtime.
Does anybody have an idea how I can fix it?

Possible or not? -->
I maybe lazy - but I want to achieve just specifiying 1 variable in SSIS package ("environment") - and all the connectionStrings should "poof" magically be adjusted to correct locations
In DTS I created a SetDTSenvironmentVariables function for all my packages - so how wouldIi achieve this in SSIS?
Function SetDTSenvironmentVariables( environment )
Folder = "MyDtsPackageFolder"
Select Case environment
case "DEV"
DTSGlobalVariables("WorkingDirectory").value = "C:Packages" & Folder
case "STAGING"
DTSGlobalVariables("WorkingDirectory").value = "D:Sql_working_directoryMy_productionSTAGING" & Folder
case "LIVE"
DTSGlobalVariables("WorkingDirectory").value = "D:Sql_working_directoryMy_production" & Folder
End Select
'
' Set Connection Properties
'
dim oPackage, oConn
set oPackage = DTSGlobalVariables.parent
oPackage.LogFileName = DTSGlobalVariables("WorkingDirectory").value & "LogsErrors.txt"
For Each oConn In oPackage.connections
Select Case oConn.Name
case "My_DB"
Select Case environment
case "DEV"
oConn.datasource = "SERVER01"
oConn.Catalog = "My_Production"
case "STAGING"
oConn.datasource = "SERVER06"
oConn.Catalog = "My_Staging"
case "LIVE"
oConn.datasource = "SERVER06"
oConn.Catalog = "My_Production"
End Select
case "Schools.xls"
oConn.datasource = DTSGlobalVariables("WorkingDirectory").value & "" & "School_Codes.xls"
case else
oConn.datasource = DTSGlobalVariables("WorkingDirectory").value & "" & oConn.Name
End Select
Next
set oPackage = nothing
set oConn = nothing
End Function
Hello-
I'm trying to read a table that has database connection information for other DBs and use this within an "Execute SL Task" task. I have seen a number of posts that talk about this possibility, but I have not been able to get it to work yet.
When I've tried to set the connection to a variable (@[User::DB_ConnectionStr]) in the Expressions area of the SQL Task, the Connection type defaults to OLE DB and I can't seem to force it back to ADO or ADO.net.
I've tried doing this with the variable being set to both a connection object and a String with the connection string, but neither seems to work.
Any suggestions? Should this be a string value of the connection string? Am I missing something when trying to set the connection type?
Thanks much!

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.
Has anyone been able to find a way to use a stored procedure with a dynamic connection string?
Hello All,
I have a SSIS package, desgined in such a way that, there is a table called connection which hold the connection name i.e similar to my DSN connection name & a ID for each DSN there is a unique ID. Now i want if there is a 10 record in the table & i have only 5 DSN connection then i'll work for 5 & for other 5 it 'll skip the process. my task is running success fully for 1 connection. i have used foeach loop container & 3 varibable for that 2 for holding the table value & 1 for refereing the recordset
thanks
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

Hi *, is there a way to connect Excel to SQL Server so that Excel serves as a frontend to SQL Server? I heard rumors that this is possible with the 2007 release.
I'm looking for a product that helps me storing massive data outside an Excel file. Right now, I'm using Palo (open source multidimensional database).

Hi SSIsians,
I have a package with Excel Destination with dynamic connection.
I did ExcelFilePath = [@user::VarSourceFolder]+[@user::VarSourceFileName]
then i changed the Delayvalidation = True.
When i try to run the package in BIDS it gives the error.
ERROR:

[Excel Source [30501]] Error: Opening a rowset for "DailySheet" failed. Check that the object exists in the database.
It saying there is no sheet in the name of "DailySheet" but when i removed the expression in connection manager property it is working fine.
Please let me know what is the problem OR how to configure the dynamic connection in ExcelSource.

I'm a newbie to SSIS so this question may cause people to point and laugh. I apologise if that's the case.
I have a configuration database that holds connection details to a remote database. I want to use these connection details to dynamically create a new connection to some remote database.
I usually work in with C# where this would be simple but I can't find how to do this using SSIS.
I have found people using configuration files but as I already have my connection data in a table I don't really want to strip it out. (Also, is it a security risk to have database connection strings stored in a config file?)
I have been able to implement a custom script object to build the connection string and assign it to a user variable within the package but can't find any way to then use that variable to connect to the remote database.
Can anyone help?
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?
Hi All,
The problem I am facing is related to dynamic configuration of package one of the package connection is DB2 connection, I tried to set the expression connection string for that connection to the variable which contains the connection string to the DB2 but when I set connection the String property then i get the error message in transformation that password is missing, I dont want to write password in connection String for security reasons so I tried to save password in connection which is not helpful I am getting the same error message package security setting I changed to "Encrypt Sensitive Data with User Key" , anywayout to overcome this problem?
Thanks,
Manoj Kumar
