Dynamic Connection Strings
Feb 5, 2007
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.
Paul

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

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?

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

All --
Please help.
I have some questions about connection strings.
BACKGROUND...
Note that I am using the "SQL Native Client OLE DB Provider", SQL Sever 2005 Express, ASP.NET, C#.NET, and VS.NET 2005.
Note that I do not want to use the "Attach a database file" type of connection string.
Note that I am using the site http://www.ConnectionStrings.com as a reference.
Note that this "Standard security" connection string...<add name="LocalSqlServer" connectionString="Server=MYTESTOFFICESERVERS;Database=MyDatabase;Uid=MyDatabaseUser;Pwd=MyDatabasePassword;" />...does not work and causes the following run-time error...A connection was successfully established with the server, but then an error occurred during the login process. (provider: Shared Memory Provider, error: 0 - No process is on the other end of the pipe.)
Note that this "Trusted connection" connection string...<add name="LocalSqlServer" connectionString="Server=MYTESTOFFICESERVERS;Database=MyDatabase;Trusted_Connection=yes;" />...works but is less-than ideal because it uses a Trusted Connection rather than a Username/Password combination.
QUESTIONS...
(A) What exactly does the error in Item 4 mean?
(B) Do 4 and 5 imply that one must use a Trusted_Connection for all SQL Server 2005 Express connection strings when the database does not reside in the web application's App_Data folder or use a "Attach a database file" type of connection string?
(C) Are there any alternatives?
(D) What do you suggest?
Please advise.
Thank you.

Let me start by asking that no one try to convince me to use Stored Procs. The examples below are a lot more simplistic then my real world code and it just gets too complicated to try to manage the quantity of SPs that I would need.
I have an application that displays a lot of data and I've created a system for users to filter the data using checkboxlist controls, dropdown controls, etc. From this, I have a "core" query that selects the fields that display in my GridView. It has a base Select clause, From clause and Where clause. From this I then add more to the Where clause to apply these filter values.
Here's an example "core" query:
SELECT Profile.FirstName, Profile.LastName, Project.ProjectNameFROM Profile, ProjectWHERE Profile.ProjectCode = Project.ProjectCode
From this if a user want's to only display profiles from NC, they could select that from the CBL and the query would be modified to:
SELECT Profile.FirstName, Profile.LastName, Project.ProjectNameFROM Profile, ProjectWHERE Profile.ProjectCode = Project.ProjectCodeAND Profile.State IN ('NC')
My code would add the last line above since the user specified that they only wanted NC profiles.
This is very simple and I have this already going on with my application. Here's the problem. In order to accommodate all of the various filters, I have to inner join and left join a bunch of various tables. Many times I include tables that have no data to display or filter on and therefore impacts performance. Here's an example:
SELECT Profile.FirstName, Profile.LastName, Project.ProjectNameFROM Profile, Project, AgentWHERE Profile.ProjectCode = Project.ProjectCodeAND Profile.AgentID = Agent.AgentID
From the query above, I have included the Agent table that holds the agent's contact information. One of my filters allows the user to type in an agents name to find all profiles assigned to it. Here's what that would look like:
SELECT Profile.FirstName, Profile.LastName, Project.ProjectNameFROM Profile, Project, AgentWHERE Profile.ProjectCode = Project.ProjectCodeAND Profile.AgentID = Agent.AgentIDAND Agent.Name = 'Smith, John'
You can see now that it was necessary to have the Agent table already joined into the query so that when I used the agent name filter, it wouldn't crash out on me.
The obvious thing would be to only include the Agent table when searching for an agent name. This is ultimately what I'm looking to do, but I need a solid method to go about doing this. Keep in mind that I currently have 16 tables in my "core" query and many of those are not needed unless the filters call for it.
If anyone has any ideas on how to simplify this process I'm selcome to suggestions. We're using SQL 2000, but are looking to upgrade to SQL 2005, if that makes any difference. I know that the way I do table joins is compliant with SQL 2005 and I'm certainly open to suggestions that will make it forward compatible.
This app is using .NET 2.0 and written in VB.NET. Thanks for any help!

I developed an application and deployed it onto a hosted provider. I use SQL 2005 Express for development SQL 2000 for production. Both systems work.
I backed up my production database and wish to use it for my development testing. I restored it as a SQL 2000 database on my development machine and changed my connection strings to point to it. I added it as a new Data Connection in Database Explorer and can see all of the data through it, but I see that all the tables now have the owner name in parenthesis as part of the table name.
My application now fails trying to find any of the tables. It works if I include the owner name as part of the SELECT statement. So much for data separation.
I don't know where to start. Is this an issue between SQL 2005 Express and SQL 2000, or is it an issue between SQL and ASP.NET, or is it a hosting provider issue, or what?????

Hey guys, don't know if this is in the right place but here goes.
I'd like some advice on optimizing the way I write my code. Here's the scenario. I have a select string for 3 different tables. One for the main gridview, and two others that are binded to dropdownlists.
So I created a Sqldatasource1,2,3 and had to create the connection strings for each one.
ex. SqlDataSource1.ConnectionString = "blah", SqlDataSource2.ConnectionString = "blah", SqlDataSource3.ConnectionString = "blah"the thing is, the connection string itself is the same. Is there a way to consolidate that? So that when I use a select/update/insert command for each sqldatasource i dont have to have another connection string? Also, having multiple connectionstrings, does that slow down the performance?

I have created a SSIS package, and got it to perform as I want.
I am having a problem though with connecting to my data source (OLE DB Source) using SQL Server Authentication.
If I use Integrated security, I have no problems. If I use SQL Server Authentication, I get errors.
Here is the connection string that works:
Provider=SQLNCLI.1;Data Source=.SqlExpress;Integrated Security=SSPI;Initial Catalog=MyDataBase
Here is the connection string that fails:
Provider=SQLNCLI.1;Data Source=.SqlExpress;Persist Security Info=True;Password=**********;User ID=myUserid;Initial Catalog=MyDataBase
The strange thing is that when I use the Connection Manager dialog screen and click on "Test Connection", I get the response that the connection succeeded. It is only when I try to run the task that I get an error.
Here is the error I am getting:
[OLE DB Source [1]] Error: The AcquireConnection method call to the connection manager "MyDataBase" failed with error code 0xC0202009.
[DTS.Pipeline] Error: component "MyDataBase" (1) failed validation and returned error code 0xC020801C.
I have eliminated the obvious errors (incorrect Userid or password). Also, I am unable to use Integrated Security as this package needs to be distributed to various systems that may or may not be on our company's primary domain.
It seems I am missing something really basic here, but am not seeing it.
Any thoughts?

What am I doing wrong?
This works:
SQLConn.ConnectionString = "Data Source=McD_DB;Initial Catalog=McDFeelGood;User ID=uuu;Password=ppp"
Now I want to put it in my web.config, but these don't work ("ConnectionString property has not been initialized"):
SQLConn.ConnectionString = ConfigurationSettings.AppSettings("McDFeelGoodConnectionString") (VS IDE says this method is obsolete)SQLConn.ConnectionString = System.Configuration.ConfigurationManager.AppSettings("McDFeelGoodConnectionString")
<connectionStrings> <add name="McDFeelGoodConnectionString" connectionString="Data Source=McD_DB;Initial Catalog=McDFeelGood;Persist Security Info=True;User ID=uuu;Password=ppp" providerName="System.Data.SqlClient" /></connectionStrings>

Hello,
I'm trying to setup a typed dataset with a table adapter in .NET 2.0, and the problem I am having is that I cannot get the table adapter to use existing connection strings setup in the web.config file. How can I get it to do so? It doesn't see the connection strings, and so it wants me to create a new connection, which I don't want to do.

I should start by saying that I'm new to SQL Server and ASP.NET. My question is about connection strings. With so many possibilities of these strings, how will I ever know what is best to use or try when one does not work. Is there a rule of thumb or an article or even a book that someone can recommend? Something that will demystify this part of working with the SQL Server and ASP.NET?
Thank you very much for any help on this.

I am trying to construct a connection string via iSeries OleDb provider. The default list of libraries on the AS400 for my user is fine for production. But in test scenarios the code/data libraries are rolled out through a sequence of test libraries. How do I specify the additional libraries for testing.
I connect fine and can execute sql. the statements like insert into TestLibrary.Table work fine, but the associated trigger code isn't called.
Would it be better to use the .Net Connection set of classes instead. I switched from ODBC to OleDb because of assumed thread safety issues.

Hello everyone! I am having some more problems while trying to get my site online. I built the site offline using Visual Web Developer Express Edition, and used "SQL Server Express" that comes with ASP.Net. Therefore, I have the ASPNETDB.mdf and mydatabase.mdf in the App_Data folder. Now, on my local machine everything runs fine. When I tried to put the site online however, I get the following error:An error has occurred while establishing a connection to
the server. When connecting to SQL Server 2005, this failure may be
caused by the fact that under the default settings SQL Server does not
allow remote connections. (provider: SQL Network Interfaces, error: 26
- Error Locating Server/Instance Specified) This is the connection string in my web.config file: <connectionStrings> <add name="ConnectionString" connectionString="Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|mydatabase.mdf;Integrated Security=True;User Instance=True" providerName="System.Data.SqlClient"/> </connectionStrings> Now, my web-host does have SQL Server 2005. Does my ASP.Net application use that though, since I have it running just through SQL EXPRESS? Also, does anyone know where I could change my "SQL Server 2005" settings? My web-host uses Plesk 8.2.0, and the database managing program is "ASP.Net Enterprise Manager", but I can't find any options anywhere to change the Server settings to allow remote connections. Any help would be greatly appreciated! Thanks in advance, Markuu

Hey all,
I'm coming from ASP and I used to have a global connection string accessible to all of my ASP pages that I'd use for all of my data access. This was really convenient because I could easily switch to a backup or local data source for testing/debug by changing the connection string in one place.
Now, I'm using ASP.NET with Web Matrix and I love the drag and drop functionality but its dropping my connection string all over the place. How can I do this and keep my connection string in one spot so I can have the same convenience of switching data sources.
Thanks in advance!

I was reading through the following post regarding dynamic connection strings:
http://forums.microsoft.com/TechNet/ShowPost.aspx?PostID=812814&SiteID=17
In this posting they talk about setting up a configuration file to setup the connection string, but I am not sure how to apply that connection string to my connection manager. When I go into my configuration file, I can see the connection string, and when I go into the advanced properties of the connection manager, under the "Named ConnectionStringFileName" property, I set the property value to the name of my configuration file, but when I test the connection I get an error that the connection string property has not been initialized.
Can someone please assist me with identifying what I am doing incorrectly?

I've been planning on putting all my connection strings for my SSIS packages into package configurations. So far, I've been using XML config files, and these strip out the passwords in connection strings which then have to be retyped every time in notepad.
Has anyone got some better guidance regarding this? Could I use another type of package config to avoid this problem?
My contraints are such that I cannot use integrated security for the packages, so the password MUST be in the connection string. However, I can place the config files in a secure location where only the package and admins have access to them.

I created a couple of Data Sources, setting them up as I have done for OLE DB connections and then deleted that connections, and created them (recreating the connections using create connection from Data Source).
But when I open them again it gives me a dialogue box (Synchronize connection string) stating following message:
This package contains at least one connection which is based on a data source. The connection string for connections and data sources listed below are currently not identical. Connection strings of connections will be updated to reflect those on the data source.
I am also using connection string variable (through Expression builder) with Package configuration for those connection
Can any tell me the solution of this problem?
I have read, in one of the forum, as a BUG but I m sure it is not as i had this problem previously on my old system but it was gone somehow (I dont know how?)
waiting for quick reply

Hello
I made certain changes in the properties in my Config file and by Change the ServerName and Database Name.
below is the example
When i execute the package it still runs. I mean theer is no server or database with that name but it still works.
<Configuration ConfiguredType="Property" Path="Package.Connections[ConManName].Properties[ConnectionString]" ValueType="String">
<ConfiguredValue>Data Source=UHS137;Initial Catalog=UH_IntegrationStaging;Provider=SQLNCLI.1;Integrated Security=SSPI;Auto Translate=False;</ConfiguredValue>
</Configuration>
Changed to
<Configuration ConfiguredType="Property" Path="Package.Connections[ConManName].Properties[ConnectionString]" ValueType="String">
<ConfiguredValue>Data Source=NOSvr;Initial Catalog=NOdB;Provider=SQLNCLI.1;Integrated Security=SSPI;Auto Translate=False;</ConfiguredValue>
</Configuration>
Then I created a new config file in which I checked in the box for ServerNam and when i change the name teher in the Config file
EXAMPLE
<Configuration ConfiguredType="Property" Path="Package.Connections[ConManName].Properties[ServerName]" ValueType="String">
<ConfiguredValue>NoSvr</ConfiguredValue>
and when executed teh package its fails.
Thats what I neede
SO coming to my question.
1)What is it doing. I mean how is the package talking to this config file
2) Irrespective of what I do in the Connection String the package executes fine, which It should not do as far as my understanding goes. Why is it doesn't matter whats in String. where as it matter in later.

Since we made some 'improvements' on our package deployment I feel I am going crazy!
This is what changed:
We created LOCAL.dtsConfig (UAT...) files.
This local file resides say at C:DWDWPackagesDWPackages.
We have user environment variable called DW_XMLCONFIG which has value C:DWDWPackagesDWPackagesLocal.dtsConfig
in this Local.dtsConfig file I have following
<?xml version="1.0" encoding="utf-8"?>
<DTSConfiguration>
<Configuration ConfiguredType="Property" Path="Package.Variables[User::varPkgDir].Properties[Value]" ValueType="String">
<ConfiguredValue>C:DWDWPackagesDWPackages</ConfiguredValue> </Configuration>
<Configuration ConfiguredType="Property" Path="Package.Variables[User::varErrlog].Properties[Value]" ValueType="String">
<ConfiguredValue>C:DWDWPackagesDWPackages</ConfiguredValue> </Configuration>
<Configuration ConfiguredType="Property" Path="Package.Variables[User::varSource].Properties[Value]" ValueType="String">
<ConfiguredValue>Data Source=SQL2;Initial Catalog=_ODS2;Provider=SQLNCLI.1;Integrated Security=SSPI;</ConfiguredValue> </Configuration>
<Configuration ConfiguredType="Property" Path="Package.Variables[User::varTarget].Properties[Value]" ValueType="String">
<ConfiguredValue>Data Source=LPET06VPC02SQL2K5Local;Initial Catalog=DW_Dev;Provider=SQLNCLI.1;Integrated Security=SSPI;Auto Translate=False;</ConfiguredValue> </Configuration>
<Configuration ConfiguredType="Property" Path="Package.Variables[User::varTargetNET].Properties[Value]" ValueType="String">
<ConfiguredValue>Data Source=LPET06VPC02SQL2K5Local;Initial Catalog=DW_Dev;Provider=SQLNCLI.1;Integrated Security=SSPI;Auto Translate=False;</ConfiguredValue> </Configuration>
</DTSConfiguration>
Any package I open gives me following dialog box
Synchronize Connection Strings
with Connection, Data Source and
Old Connection =Data Source=LPET06VPC02SQL2K5Local;Initial Catalog=DW_Dev;Provider=SQLNCLI.1;Integrated Security=SSPI;Auto Translate=False;
New connection =Data Source=sql11;Initial Catalog=DW_UAT;Integrated Security=True
All of my packages have connection called TargetNet.
My question; Why it does not pick up value from dtsConfig file instead using connection under Data Sources (TargetNet).
thanks a lot!

Hello,
I am working on porting a Windows Forms VB.net VS 2003 app with a SQL 2000 backend - to using VS 2005 with SQL Express 2005.
I cannot seem to figure out how to set my connection string to work in the new environment. I have already recreated my database in SQL Express 2005 and ported the VS project to VS 2005.
The old string was (in my app.config file):
<add key="ConnectionString" value="workstation id=MAIN1;packet size=4096;user id=sa;data source=MAIN1;persist security info=True;initial catalog=Dbname;password=####" />
Any ideas?
Thanks,

Everything is set up the way it should be, as far as we can tell.
However, when we drop in a SQL data source and try to configure, it, we
get a blank box for choosing the connection string, and it won't let us
make a new one.
Has anyone encountered this before? If so, how can we fix it?

Hey guys,
I am pretty new to reporting software and I was just wondering in reporting services 2005 when working with multiple datasets and data connection string in order to populate text boxes if the data is a number it is prefixed with SUM at the start of the expression and if it is text it is prefixed with FIRST even though it is just for one value.
I was wondering if this is normal or have I messed up somewhere?
Many thanks.
