Changing The Connection String At Runtime? C# 2.0
Oct 24, 2007
How can i change the connection string at runtime?
Scenario is, I want my customer to enter server name, database name, and some parameters at the installation time then i will use these entries to build the connection string and persist it into the app.config.
also not only at installation time but also at runtime while the program is running. i wanna make these entries as options which can be modified at any time
so, How can i do that ?
Thanks in advance

Hello
I am connecting to an Intersystems Cache' database and extracting data with a DataReader.
Does anyone have a suggestion or example on how to change the SQL String at runtime?
Everything I could find only dealt with setting the SQL String at design time.

This is the first time I have used SSIS, so please bear with the ignorance.
I have a super simple package that inserts x000's of rows into a temporary table. The data source is a file that the user will upload. I need to be able to tell the package what file to upload. I'm thinking the simplest thing would be to edit the connectionString property of the SourceConnectionFlatFile at runtime. Is this possible? What form should the file path be in (UNC, other)? And, are there any other considerations I should be aware of?
Thanks!

Hi all
I have a flat file.I am trying to set the value for the property "HeaderRowsToSkip" during runtime.I have set an expression for this in my "flat file connection manager". But this is not working.The connection manager is not able to take the value during runtime.
My expression is as follows:
DataRowsToSkip : @[user:: Var]
where "Var" is my variable which gets the value from the rowcount component and trying to set it back to the "HeaderRowsToskip" property.
I ve even tried setting the value to the "HeaderRowsToSkip" property in the expression builder.
Its not working....
Can anyone help me out in solving this????
Thanks in advance

Now that I have figured out how to connect to a foxpro database...
Could anyone tell me how to change the connection string on the fly?
I would like to make it possible, from the command line (using dtexec) to specify a portion of the connection string.... incorportate this portion into the connection string and then instruct the connection manager to use this connection...
For example I have a number of foxpro databases to import, they will be place in a directory structure like this:
TopLevel
TopLevelNewYork ransactions.dbf
TopLevelLondon ransactions.dbf
TopLevelSydney ransactions.dbf
I'd like the user to be able to specify which city's files to load each time the package is run..
dtexec /f MyPackage /set Package.Variables[User::THECITY].Properties[Value];"London"
And when the package starts the THECITY variable would take the value "London"
But I'm not sure how to then affect the connection string property of the connection manager... there seems to be no way to specify that it take its connection string property from an expression...
So I'm lookin for some way which would cause the Connection String property of the coneection manager to become:
Driver={Microsoft Visual FoxPro Driver};sourcedb=d:TopLevelLondon;sourcetype=DBF;exclusive=No;backgroundfetch=Yes;collate=Machine;
Jsut to recap, the provider for this connection manager
is a ".Net ProvidersOdbc Data Provider" which I've been forced to use becasue the OLEDb provider for Foxpro has been rendered useless by service pack 1
Thanks in advance

Hi!
I create a SSIS Package for ETL on my own machine. During development database was also on my machine. For access to this database an OLE DB connection was defined within a package in BI Development Studio. Everything worked well both in debug mode and testing package itself.
Finally I need to load data to a database on a different machine using this package.
I used several scenaries:
1) simply copied the package-file to estination machine, open it for execution, in section "Connection Managers" I edited connection string manually - changed server name and Initial Catalog. And try to execute.
2) on the destination machine I manually created an OLE DB connection (using Microsoft Data Link) to a different database (test succeded), Changed the extention of the connection file 'udl' for ' txt ' and copied its connection string to the field connection string in section "Connection Managers" (pointed in variant 1) ).
3) use Package Configurations, copied the deployment to destination machine, installed the package the way like written here - http://msdn2.microsoft.com/en-us/library/ms365338.aspx. Changed exported properties - Server name, Initial Catalog and also the whole Connection String. Also try to execute.
In all cases I recieved the same error execution message :
"Errors in the metadata manager. Either the database with ID of " OLD_DATABASE_NAME " does not exist in the server with ID of " NEW_SERVER_NAME " or the user does not have permissions to access the object."
As for access (username/pass) settings they are the same for both of them, I have the same administrative rights on both machines. And more with the same rights the ole db connection made was made manually in variant 2 - succeded!!! So I don't think the problem is here.
As for Error message - I think somewhere the OLD name of database (Initial Catalog) is saved, though I tried to change it. Though the NEW value for the server name is substituted.
Please, help me. I don't know what else can I try. And it is not a single case for my practice. So I think - something wrong in my actions.

Scenario:
130 dtsx packages using 4 matching connections.
3 of those connections are stored in an SSIS Configuration table in an Operational database.
The last connection is in a shared data source and points to the Operational database so the packages can grab the others.
Problem:
It's time for deployment and all of those connections must change to production servers.
The 3 are no issue, just change the ConfiguredValue in the SSIS Configuration table on the production box to point to the other production servers.
However, the fourth one... I had made an assumption that when you changed a shared data source it filtered down throughout all the packages. We all know what assumptions do to you.... So. I need a way to change all 130 connections (and be able to change ALL packages quickly and simply for other projects in the future)
Solution:
It has been suggested that we use another package to run though all of the packages and change the connection with a script task. I can live with this (and more importantly so can our DBS's who have to deploy).
I have one snippet of code to ADD a connection using a variable holding the connection string, but we dont' want to add one, just change an existing one.
Has anyone else done this? Or had a similar problem and way to fix?
We are likely to have many projects in which the connections MUST change at deployment, and the idea of going into every package to make the change is sad at best... We would be more likely to move back to a competitor's product that has a connection repository, than continue with SSIS.

I’m working with a team of programmers who are in the process of upgrading an older ASP application to ASP.NET 2.0 (VB). The existing application connects to the SQL Server Database using different Logins, depending on the User logged into the ASP Application.
We are hoping to do the same using ASP.NET 2.0, although we haven’t been able to find a simple solution. The most feasible solution we have found includes programmatically trapping all the Selecting etc events and changing the SqlConnection at run time. This allow for ease during Designing of the Web Pages, but implementation requires adding code to each web page (>100 pages).
We are hoping there may be a simple solution which can be implemented once for the application where the event can be trapped at the application level, and the SqlConnection set at this point. Or possibly another type of solution such as creating a new class etc that can be used?
Does anyone have a simple solution where the username / password for the Database Connection can be set at run time?

Here is my screnario, While development I am using Data source name called "DevDatasource1" and when I am deploying it to other evnironment the datasource name will change let us say "QADatasource".
I have to create a script for changing the datasource(i.e. DevDatasource1 to QADatasource). How I can achieve I this using the setItemdatasource?

Hiya guys,
The question:
Can I design data flows with an XML Source pointing to file system xml files, and but run them against variables? I can see the properties at design time (Accessmode=0,1,2; XMLDataVar="User::XMLData), but the XMLSource object doesn't appear to have expressions enabled to change this at runtime, nor do these properties seem to be exposed to configurations.
The scenario:
I have a package that reads through (potentially thousands) of XML files, and having identified the embedded message "type", transforms them via XSLT to an easier XML format (XML Datasource can't cope well with multiple namespaces etc). Then send this the new file off to a type specific dataflow task to send contents to database.
For performance (and other) reasons I'd rather XSLT to a single shared variable and use this variable as the XML source in the data flows (Rather than writing out to the filesystem [via xslt] and immediately reading it back in each time [via datasource]).
But designing the data flow task using a variable as xml source is frustrating for a bunch of reasons - not the least being:
(a) The variable needs to be populated with sample xml data at design time. But this could only ever match one dataflow at a time (fine at run time, but painful at designtime - leading to validation errors popping up all around the place.)
Yes I could have a seperate variable for each xmlsource - but that just makes things more complicated up front and also leaves me with 20+ large, type specific, xml variables floating around at runtime of which only one is ever being used per import - which just doesn't feel right to me.
(b) populating the variable with sample xml at design time is painful due to it being a string - and not accepting hard returns etc that are in text files, design time changes etc)
Using a file XML source at design time is infinitely easier, when I get a design time change - I can just amend the XSLT and run the appropriate task to produce a sample XML file to design against.
Any ideas?
Ta.
Gus.

I use SQL Server 2012 and visual studio 2010.I created SSIS Project with task "Execute Package". Control flow view as: Package1 (execute package) -> Package2 (data flow).Data flow in Package2 view as: ADO.NET source -> ADO.NET destination.
When I started Package2, it's work. I havn't errors.But when I started Package 1 I have error "Unable to get managed connection from the Connection Manager runtime". In execution log I see that ADO.NET source produced this error on verification stage. Package failed on verification stage, not on execution stage.Why when I started Package 2 it work, but when I started Package1 (and Package1 started Package2) it failed?

The problem:
I have a package that does this
1. Deletes a SQL Server database.
2. Recreates it with the tables ready to take data.
3. Executes a Flow Task that puts the data into the tables.
So far so good. The problem I have is that everything
is loaded correctly as long as the tables are in place
before I try to execute the package. When the first
step deletes the database I get an error because
the connection manager cannot find the tables that
are defined in the database that has been removed
and the package seems to disregard the fact that before
the data gets loaded the whole structure will already
be in place. What should I do to convince the package
that the connection manager will have the target
database set up when the data needs loading?
Thanx for any ideas.

I added a connection (ADO.NET) object by name testCon in the connection manager - I wanted to programmatically supply the connection string. So I used the "Expressions" property of the connection object and set the connectionstring to one DTS variable. The idea is to supply the connection string value to the variable - so that the connection object uses my connection string.
Then I added a "Backup Database Task" to my package with the name BkpTask. Now whenever I try to set the connection property of BkpTask to the testCon connection object, by typing testCon, it automatically gets cleared. I am not able to set the connection value.
Then after spending several hours I found that this is because I have customized the connection string in testCon. If I don't customize the connection string, I am able to enter the "testCon" value in the connection property of the BkpTask.
Is this an intrinsic issue?

I used to do this in DTS but wondered how to do it in SSIS. I have a For Each ADO recordset loop that reads these four columns into variables:
DataSource Name, Name(for a WHERE clause), user and password.
For each "Building" there is a new server to connect to, with identical tables. I have 10 tables in the loop to pump from one database to a SQL 2005 database (i.e. 10 dataflows). I want to set the source connection information with the variables. My questions:
1. How do I set the connection information for the source connections? Do I just set the properties for the connection manager and then it sets for all the sources? What property do I set--do I need a script task?
2. How do I use the values from the "Name" column in a WHERE clause in each data flow?
Thanks!

Hi all. Sorry about bothering you again but I have no choice, I'm afraid. This time I have to add a connection manager at runtime. I have a script that examines rows in a huuuuuuuuuuuuge file and it turns out that I will have to redirect different rows into 95 different text files. I would like to avoid the pain of creating the files and connection managers manually. I have a source script component that runs asynchronously (the only way basically it can run as a source) and I wonder whether this time, when I change the connction string on the manager at runtime inside the script, it would run properly. Can anybode tell me, please?

At one point in my package I call a simple web service that kicks off a process on a remote server using a Web Service Task . I need to be able to point the task at a test instance while I'm testing and a different one when it goes to production. The simple answer (you'd hope anyway) is to just store the ConnectionString for the HTTP Connection Manger in Package Configurations for TEST and PROD. I did this and when the package runs, the connection manager's connectionstring does get changed, but the web service task doesn't use this value. It uses the value defined in the WSDL file which in my case contains the URL for the TEST instance.
Am I missing something obvious? Do I really have to get the WSDLs from PROD and TEST and deploy both of them to the appropriate environment? What does the ConnectionString in the HTTP Connection Manager actually do then?
Thanks for any insight you might have.

I need to add the current date to the end of the filename of a flat file at runtime.
This was previously done with ActiveX script in SQL Server 2000.
oConn = DTSGlobalVariables.Parent.Connections("FlatFileConnectionManagerName")
oConn.DataSource = sNewFileName
oConn = Nothing
I would really appreciate if someone could give me some information on how to achieve this in SQL Server 2005.
Thanks in advance!

I have been working with flat file connection managers for a while now, and I have found it very useful to set properties on all types of SSIS objects using expressions that are set to SSIS package variables.
We have recently moved towards using a centralized application configuration infrastructure, so we are now loading up all application configuration information from our own system -- it's actually based off of the 2.0 ConfigurationManager.
I have developed a custom control flow task that will retrieve all of the SSIS variable information from our own application configuration system and set all of the SSIS variables as the first step in a package.
When I have been using this to set the SSIS Variables which are used in expressions for the HeaderRowsToSkip and DataRowsToSkip (there may be others, but I have not tested them yet) properties of flat file connection managers, these values are not being used -- instead it is using the values for the variables that are defined in the package itself (i.e. the default values that I set up in BIDS when developing the package). The ConnectionString property on the flat file connection manager does not exhibit this behavior.
Can anyone provide any insight on this? Is this a bug in SSIS, or is there something that I am missing here?
Thanks in advance.

In a column I have some values for part names. The 6th character tellsyou where the part came from, and this is the same scheme for everysingle part in the database.If I want to do something like return the basic name of a given part,without the factory identifier character, I need to replace thatcharacter with a '_' character. (So for instance '11256CA' and'11265AA' and '11256MA' would all just get turned into '11256_A' andonly one row would be returned in the SELECT DISTINCT statement)I know how to replace an instance of a given character using replace(),but how can I alter a specific character in a string if all I know isthe index of the character within the string?TIA,-CS

I need to change a string in a .txt file using .NET, the .NET code will be executed by an SSIS package and the file needs to be changed so it can be used by another process which looks at that specific line (line 9 value: 'set ASOF=20080424'), for that specific date string.
What method in .NET can I use to perform this task? Should be very simple, correct?

I basic question but can someone help.
I have a SELECT statement, the result of which populates a
datagrid. The first column has consecutive dates in it and I want
to hyperlink each date to a seperate Javascript function (the
Javascript is created on the fly and is unique for each date). I
need a different function name for each function and so tried the date
but "/" is not allowed in the Javasript function name. I think
the easiest way will be to produce a new column with the date expresses
ddmmyyyy, ddmmyy or some such unique number (but not dd/mm/yyyy).
I tried :-
"CASE " & _
"WHEN t3.date = t3.date THEN (DAY(t3.Date) + MONTH(t3.Date) + YEAR(t3.Date)) ELSE NULL END AS [javaKey]
but this adds the year to the month to the day - not a unique result as 1/2/06 and 2/1/06 are the same.
I am just getting to grips with VB.Net (as an amature) but am a distinct beginner at SQL!
Many thanks

I'm having a BIG problem, this is my 3rd day looking for answer !I'm trying to create a custom membership provider with MS SQL database 2005 but not the default ASPNETDB.

I have been trying to host my website on Go Daddy for about 3 weeks and I have cleared several problems but this one remains. I can get into the ASPNETDB database for doing logins , etc but I cant access my database called "PINEmgt".
To try to understand where the problem is located,I built a very simple application without login controls and put on it one Detailform accessing a single line table "Signin". I continually get the error message I got with my real app :"The connection name 'PINEMgtConnectionString2' was not found in the applications configuration or the connection string is empty. " There is only one connection string in my app -'PINEMgtConnectionString2'. When I run the app locally on my machine it works. After I move everything to Go Daddy, I get the error message and the following dump"
Line 24: </Fields>
Line 25: </aspetailsView>
Line 26: <aspqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStringsINEMgtConnectionString2 %>"
Line 27: InsertCommand="INSERT INTO Signup(first_name, last_name, email, customer_id) VALUES (,,,)"
Line 28: SelectCommand="SELECT * FROM [Signup]"></aspqlDataSource>
This is indeed the code from my single page app.
The dump is:
[InvalidOperationException: The connection name 'PINEMgtConnectionString2' was not found in the applications configuration or the connection string is empty.]

here is my code the falue of pr_h_reqby is "Test"
Dim strconn As New SqlConnection(connstring)
Dim myReqdata As New DataSet
Dim mycommand As SqlDataAdapter
Dim sqlstr As String = "select pr_H_reqby from tbl_pr_header where pr_h_recid = " & recid & ""
mycommand = New SqlDataAdapter(sqlstr, strconn)
mycommand.Fill(myReqdata, "mydata")
If myReqdata.Tables(0).Rows.Count > 0 Then
'lblReqID.Text = myReqdata.Tables(0).Rows("reqid").ToString
lblNameVal.Text = myReqdata.Tables("mydata").Rows("pr_H_reqby").ToString()
lblEmailVal.Text = myReqdata.Tables("mydata").Rows("pr_h_reqemail").ToString()

I have a child package where the ConnectionString property of a Connection Manager is set by a Parent Package Variable Configuration. I set up a script task that brings up a message box with the value of the ConnectionString property right before the dataflow task.
MessageBox.Show(Dts.Connections["CPU_*"].ConnectionString.ToString());When I run the parent package, the message box shows that the connection string is changing with every iteration, but in the dataflow it always draws the data from the same source.
The connection manager is an ADO.Net type, RetainSameConnection is set to False, and I've been researching this for days.
(Update 2/23/2015): To make this stranger, when I look at the diagnostic logs, they tell me that when the new connections are being opened they are using the new connection strings.

Hi
I am trying to switch between oracle and sqlserver databases to read the source data. I have used a parameter file to specify the connection parameters. For SQLserver the connection looks like in the file as below:
<?xml version="1.0"?><DTSConfiguration><DTSConfigurationHeading><DTSConfigurationFileInfo GeneratedBy="abvsh" GeneratedFromPackageName="Package" GeneratedFromPackageID="{8A304BF7-5325-4079-9D92-2B9BBF8793AA}" GeneratedDate="1/23/2007 4:46:08 PM"/></DTSConfigurationHeading><Configuration ConfiguredType="Property" Path="Package.Connections[dl.PM_DW].Properties[ConnectionString]" ValueType="String"><ConfiguredValue>Data Source=dl;Initial Catalog=PM_DW;Provider=SQLNCLI.1;Integrated Security=SSPI;Auto Translate=False;</ConfiguredValue></Configuration><Configuration ConfiguredType="Property" Path="Package.Connections[dl.PM_DW].Properties[Description]" ValueType="String"><ConfiguredValue></ConfiguredValue></Configuration><Configuration ConfiguredType="Property" Path="Package.Connections[dl.PM_DW].Properties[InitialCatalog]" ValueType="String"><ConfiguredValue>PM_DW</ConfiguredValue></Configuration><Configuration ConfiguredType="Property" Path="Package.Connections[dl.PM_DW].Properties[Name]" ValueType="String"><ConfiguredValue>dl.PM_DW</ConfiguredValue></Configuration><Configuration ConfiguredType="Property" Path="Package.Connections[dl.PM_DW].Properties[Password]" ValueType="String"><ConfiguredValue></ConfiguredValue></Configuration><Configuration ConfiguredType="Property" Path="Package.Connections[dl.PM_DW].Properties[ProtectionLevel]" ValueType="Int32"><ConfiguredValue>1</ConfiguredValue></Configuration><Configuration ConfiguredType="Property" Path="Package.Connections[dl.PM_DW].Properties[RetainSameConnection]" ValueType="Boolean"><ConfiguredValue>0</ConfiguredValue></Configuration><Configuration ConfiguredType="Property" Path="Package.Connections[dl.PM_DW].Properties[ServerName]" ValueType="String"><ConfiguredValue>dl</ConfiguredValue></Configuration><Configuration ConfiguredType="Property" Path="Package.Connections[dl.PM_DW].Properties[UserName]" ValueType="String"><ConfiguredValue></ConfiguredValue></Configuration></DTSConfiguration>
the pacakge runs fine. But when i change the connection to Oracle, it gives me error.
The config file looks like when i put oracle connection is as follows:
<?xml version="1.0"?><DTSConfiguration><DTSConfigurationHeading><DTSConfigurationFileInfo GeneratedBy="I2vshrivas" GeneratedFromPackageName="Package" GeneratedFromPackageID="{8A304BF7-5325-4079-9D92-2B9BBF8793AA}" GeneratedDate="1/23/2007 4:46:08 PM"/></DTSConfigurationHeading><Configuration ConfiguredType="Property" Path="Package.Connections[dl.PM_DW].Properties[ConnectionString]" ValueType="String"><ConfiguredValue>Data Source=pm62;User ID=pcm_62;Provider=OraOLEDB.Oracle.1;Persist Security Info=True;</ConfiguredValue></Configuration><Configuration ConfiguredType="Property" Path="Package.Connections[dl.PM_DW].Properties[Description]" ValueType="String"><ConfiguredValue></ConfiguredValue></Configuration><Configuration ConfiguredType="Property" Path="Package.Connections[dl.PM_DW].Properties[InitialCatalog]" ValueType="String"><ConfiguredValue></ConfiguredValue></Configuration><Configuration ConfiguredType="Property" Path="Package.Connections[dl.PM_DW].Properties[Name]" ValueType="String"><ConfiguredValue>dl.PM_DW</ConfiguredValue></Configuration><Configuration ConfiguredType="Property" Path="Package.Connections[dl.PM_DW].Properties[Password]" ValueType="String"><ConfiguredValue></ConfiguredValue></Configuration><Configuration ConfiguredType="Property" Path="Package.Connections[dl.PM_DW].Properties[ProtectionLevel]" ValueType="Int32"><ConfiguredValue>1</ConfiguredValue></Configuration><Configuration ConfiguredType="Property" Path="Package.Connections[dl.PM_DW].Properties[RetainSameConnection]" ValueType="Boolean"><ConfiguredValue>0</ConfiguredValue></Configuration><Configuration ConfiguredType="Property" Path="Package.Connections[dl.PM_DW].Properties[ServerName]" ValueType="String"><ConfiguredValue>i2pm62</ConfiguredValue></Configuration><Configuration ConfiguredType="Property" Path="Package.Connections[dl.PM_DW].Properties[UserName]" ValueType="String"><ConfiguredValue>pcm_62</ConfiguredValue></Configuration></DTSConfiguration>
The error which i get when running from oracle source is this:

Please let me know if you guys have any suggestion in what i am doing wrong.
