Apr 14, 2008
Hi all,
I am able to set dynamic source for the text file(flat file) but i want to set the connection string (file name) to excel source dynamicaly. I have tryied lots of time by taking a variable in foreachloop container . Variable is itself able to pick the file name dynamicaly but whern i am tying to set connectionstring to excel source it gives error.
Steps that i have done: -
1) Drag foreachloop container
2) set directory,FileNameRetrieval,FileSpec
3) Made VariableMapping
4) Now drag a dataflow task in the foreachloop container
5) select excel source
6) When i am selecting varaible as connectin string from properties of excel connectin manager, i am getting this error : -

Hi SSIsians,

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: An OLE DB error has occurred. Error code: 0x80040E37.
[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.

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

Hi,
I've seen a number of posts similar to this but i still cannot figure out what i need to do to get it working. So here goes with a couple of newbie questions.
Question 1:
Once created how do i go about executing a SSIS package. I want to be able to call it from a C# application from which i pass in a couple of parameters?
Question 2:
How do i go about setting the file path of my Excel source to a dynamic value passed at runtime. I want to be able to loop through a number of Excel files and do some processing on them. I've set up a variable (which i think i need to do) after that i get stuck however. Some other posts suggest configuration packages but i cannot get my head around how they work?
Any help on this matter would be gratefully recieved.
Thanks in advance,
Grant

i've been reading some problems with excel source data being force as
numeric type when there are string/numeric type in the data, but adding
IMEX=1 to the extended properties will fix this problem...this is true
but not in my case...
say my excel file have about 40 rows..if row 1-39 in column A are all
NULL and row 40 has a string in it, the string in row 40 will not be
converted and the excel source is forcing this column A data type to be
numeric..having IMEX=1 in there does not work..however..if i add a
string anywhere in row 1-8 in column A, the the string in row 40 will
be converted because the external data type now is a string..
anyone know how to solve this problem?

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.

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.

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 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).

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.

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

I need to create a report that lists other reports in the SSRS database. So I created an XML Data Source. But no matter what, I can't seem to parameterize this connection string so that it'll always point to whichever report server the report is deployed to. I know that I can change this data source once I've done deployment, however I don't want to have to change this whenever I change from SIT to UAT to Production. Is there a way to achieve this?
I tried:
"http://" & Globals!ReportServerUrl & "/ReportService2005.asmx"
="http://" & Globals!ReportServerUrl & "/ReportService2005.asmx"
http://Globals!ReportServerUrl/ReportService2005.asmx
=http://Globals!ReportServerUrl/ReportService2005.asmx
Globals!ReportServerUrl & "/ReportService2005.asmx"
=Globals!ReportServerUrl & "/ReportService2005.asmx"
All to no avail
Thanks,

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?

I have a simple package, which reads a flat file source, does some transformation, and outputs to a flat file destination. The package runs as a SQL Agent job, so I have the flat file source and OLEDB connection ticked and configured on the data sources tab.
What I would like to do is get hold of the flat file source connection string property from inside the package at run time, and use it to set the flat file destination connection string using property expressions.
The easy option is to set the destination in the agent job, but I'd like to add a date/time stamp to the destination filename.
Is this possible?
Thanks,
Greg.

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?

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?

Hi All,
I created a SSIS package to import an excel spreadsheet into my data warehouse.
When I run the package it runs fine. When I created a SQL Job to run the package I get the following error:
Option "Source=D:HelpDeskImportBook2.xls;Extended" is not valid. The command line parameters are invalid.
Now if I look at my source connection string in the job it looks like the following:
Provider=Microsoft.Jet.OLEDB.4.0;Data Source=D:HelpDeskImportBook2.xls;Extended Properties=HDR=YES;EXCEL 8.0;HDR=YES";
Does anyone know why it appears that my connection string looks like it is being cut off and does anyone know how I can correct the problem?
Thanks,
Scott

I have a folder of excel files with different file names and sheet names inside the file. So File A could have Sheet1A and file B could have Sheet2B.
The assumption is that the sheets would have similar data in them for all files even though sheet names are different. I was able to dynamically create the excel connection string using a for loop and choosing the Data Access mode of the excel source to be Table name or View name variable. I have run into a "[DTS.Pipeline] Error: "component "Excel Source" (1)" failed validation and returned validation status "VS_NEEDSNEWMETADATA".
Was wondering if anybody was able to play in such a scenario and resolve the issue.
By the way a lot of the posts in this blog helped me get this far so thanks for all the posts.

I currently have the following connection string set up in Excel to connect to my SQL db:
Â
Provider=SQLOLEDB.1;Persist Security Info=True;User ID=XXXXXX;Initial Catalog=YYYYY;Data Source=SQL;Use Procedure for Prepare=1;Auto Translate=True;Packet Size=4096;Workstation ID=PROJMNT1;Use Encryption for Data=False;Tag with column collation when possible=False
 What I would like to do is replace the Workstation ID (which apparently is hard coded?) so that the user's workstation name pulls (%COMPUTERNAME%) so that I can see who is connecting, using what, for how long etc etc.
Is there anyway to accomplish this?
