Dynamically Changing The Connection Properties
Apr 18, 2007
I want to transfer data from one server to another by using SSIS. i want the connection string to be dynamic and also according to the some other variable, the transforming data is changing.
Could you provide me the solution thet how i am able to change my connetction string dynamically and the other variable too.
i am using VS 2003 as front end and SQL server 2005 as a backhand.
Due to VS.NET 2003 i am able to create DTS packages but i have to migrate it and then anly i am able to use it in JOB in SQL server agent of SQL server 2005.
is that any code or any stored procedure from which i am able to migrate DTS packages to SSIS packages.
Thank you

I have an ODBC connection string that is working fine with the following properties:
Database="XXXXXXX",Network="YYYYYY"; strangely no server is specified in the string, but it is specified in the ODBC Connection file.
I am trying to do a new server registration in SSMS for this database.However, I don't understand where the network spec is placed.
Under Registered server name I've tried:
YYYYYYXXXXX
When I browse the server for the database instance list, I receive "network path was not found".
I even tried:"XXXXXXX",Network="YYYYYY" for the registered server name.Same error message.
What am I doing wrong ?

Hi everyone,
I€™d like to read the SqlStatement property for a Sql Task from a Script Task (previously Sql Task is executed) in execution.
Keeping on mind that such SqlStatement receives an input parameter.
Is it possible? I think so but how do I such thing?
Let me know if you need further details.
Thanks a lot for your time and thoughts,

In our replication environment, the subscriber is initially set up with an snapshot of the publisher database. However, after that, the subscriber and publisher are different and we can never re-initialize from a snapshot again (we purge data on the publisher to reduce the database size but do not purge the same data on the subscriber; we do this by stubbing out the stored procedures on the subscriber that purge data on the publisher).
If an article is added or dropped from the publication, using snapshot and synchronize, just these changes are propagated to the publisher (without an entire new snapshot).
However, if an Article Property is changed (change SCALL to MCALL under Statement Delivery options for the UPDATE statement), the interface REQUIRES an entire new snapshot. Is there any way I can avoid the new Snapshot? It overwrites the subscriber database and this cannot happen!

Hi,
I have a MS SQL Server Express database wich I upsized once from MS
Access. I can connect to it and get/insert data but I can't update the
field properties.
I've used Access 2003, Visual Studio .Net and SQL Server Web Data
Administrator, but I can't change the properties of existing tables. I
cán add new tables and add their properties afterwards. Since I have a
lot of tables it would be too much work too recreate them all. So how
can I edit my existing tables?

My requirement is to have my report display on one 11 by 8.5 page. Is there a way to programmatically change the PageHeight report property based on the number of rows returned in a table? i.e., if the rowcount for table x >= 10, change PageHeight to 9.5.
Any ideas?
Thanks.

We have a query in which we have data in fields called TS1Min, TS1Max, TS1Avg, TS2Min, TS2Max, TS2Avg etc.
We have a different table in which we define that vale of TS1, TS2, as an example TS1 might equal RED, TS2 might equal BLUE.
We have written a query that puts TS1Min, TS1Max, TS1Avg, TS2Min, TS2Max, TS2Avg in a temp table #TEMPA
and we also put the values of RED and BLUE in another temp table #TEMPB
now we want to select * from #TEMPA but rename the headings TS1Min to display RED-TS1Min, TS1Max as RED-TS1Max, TS1Avg as RED-TS1Avg etc...
any ideas on how to do this

Hi,
In my report, I've to print the address of the customer in a form which is in a pre-defined format. So while printing, the line number and position should be specified by the user. Is there any ways in SSRS to change the position of a textbox/any control dynamically by inputing the x and y coordinates? If there is a way please let me know that.
Thanks in Advance,

Hi Everyone,I have a question about dynamically changing the length of a varchar(n)field, in case the value I'm trying to insert is too big and will givea "truncated" error, but before the error is given! i.e. Is there somekind of a way to "test" the length of the field while Inserting thevalue into it, and to have it automatically increase its length to thelength of the value being inserted, in case the value is too big?I've been able to do this in a "primitive" way, simply by identifyingthe specific error number in case the value is being truncated, andthen increasing the length of the varchar(n) field by using the ALTERcommand, and then duplicating the insert statement, but is there astandard (shorter) way of doing this?Here is my code (I'm working in an ASP environment):<%var_txt = "abcdefghijklmnopqrstuvwxyz12345678789"sql = "Insert Into Table1 (text) Values ('" & var_txt & "')"On Error Resume Nextconn.Execute sqlIf err = -2147217833 ThenResponse.Write "Error Recognized Successfully!<br /><br />"sql = "ALTER TABLE Table1 ALTER COLUMN text VARCHAR(" &Len(var_txt) &") NOT NULL"On Error Resume Nextconn.Execute sqlIf err<>0 ThenResponse.Write "Error while trying to alter Column:<br/>" & err & "= " & err.description & "<br />"ElseResponse.Write "Column altered successfully to: " &Len(var_txt) &"<br />"sql = "Insert Into Table1 (text) Values ('" & var_txt &"')"On Error Resume Nextconn.Execute sqlIf err<>0 ThenResponse.Write "<br />Error number 2:<br />" &err.description &"<br />"ElseResponse.Write "Now it was added successfully!HaHa!<br />"End IfEnd IfElseResponse.Write "Success."End If%>Thanks in advance!

In my SSIS package I have a loop container that I am running the same code against 4 servers.
I have the package export the SQL data to an Excel spreadsheet that has multiple tabs.
Is there a way I can change the tab on the fly or do I need to create a Connection for the same spreadsheet 4 times
Each Connection pointing to a different tab?
I tried to set up a expression for the Excel Connection Manager to use the InitialCatalog for the tab and change it
based on the script in the loop however this causes the following error:
An OLE DB error has occurred. Error code: 0x80040E21. An OLE DB record is available. Source: "Microsoft Native Client" Hresult: 0x80040E21 Description: "Multiple-step OLE DB operation generated errors. Check each OLE DB status value, if available. No work was done.".
Cannot create an OLE DB accessor. Verify that the column metadata is valid.
Thanks in advance

Before I launch into a long description of the issue, I was wondering whether its possible to dynamically amend the file path held in a configuration string? (I'm looking at the Package Configurations Organizer)
Basically recreating the /CONF switch in the dtexec utility
So a parent package could somehow tell a child package to pull its configuration from a selection of different xml config files at run time... I couldn't see a variable in the child package to set from the former
My only idea at the moment is to replace the Execute Package Task with an Execute Process Task, and directly invoke the child using dtexec & an expression to dynamically set the /CONF switch..
thanks
James

Hello. What I'm trying to do should be fairly simple, but after an hour of searching and trials, I can't seem to get it working.When I run my website on my test machine, I would like it to use a certain value for my connectionString. But when it's run on the live server, it should use a different connection string. This way, when it's on the test server it'll use the test database.In my Web.Config file, I have this:<connectionStrings> <add name="myConnectionString" connectionString="Data Source=TEST_DB;Initial Catalog=tester;Integrated Security=True" providerName="System.Data.SqlClient" /></connectionStrings>I would like to be able to change the connectionString in something like the Global.asax file, when the application is loaded. I'd check for a certain environment variable, or some other condition, and change the value of the connectionString.I tried this in my Global.asax, but it told me the value was read_only: ConfigurationManager.ConnectionStrings["myConnectionString"].ConnectionString = "Data Source=LIVE_DB;Initial Catalog=live;Integrated Security=True" Does anyone have a good way of doing this, so I don't need to juggle Web.Config files when I publish my site? Thanks.

Does anyone know how to change the task name displayed within a ForEach Loop Container (or of the ForEach Loop Container task itself) based on a variable. I am pretty familiar with setting variable values during task execution and using expressions to alter task properties based on variables. I have tried using an expression to alter the value of the Name property of the ForEach Loop Container but the name of the ForEach Loop Container does not change during execution. Since the color of the various tasks change during execution, I would think that the task names could be changed as well.

I have a scenario where we have to handle dynamically changing source columns.
For example , some times in the source files the number of columns will be increased or decreased, new columns can be added in the middle or in the end of the source file.
How to handle this kind of scenario in the SSIS ?

I have SSIS packages that send success/failure email upon completion, and I'd like to add a note that identifies the server and database used. I can certainly add variables to the packages and use them when constructing the email, but I'd prefer to get the information directly from the OLE DB connection itself. Is there a way to access the connection string from within a control-flow VB script task? Furthermore, can I get the data source and initial catalog from that connection string, or do I need to parse it myself?
Thanks!

Howdy folks,
I'm trying to get a better idea of how I should set some of the SSCE connection properties. I will be deploying the application on a WinCE5 board with a 4G flash storage card and 512MB RAM. The application must run 24/7 with a medium amount of traffic. At any given point I expect up to 3 connections to the same database. I'd really like to keep performance high without risking any database corruption issues. As such, I need to make sure my connection properties are optimized.
I read from Joao's article that setting DBPROP_SSCE_MAXBUFFERSIZE = 1024 gave a considerable performance increase, while anything higher gave diminishing returns. Is this for a certain amount of RAM, or is it uncorrelated to RAM size?
What's the best practice for specifying DBPROP_SSCE_TEMPFILE_DIRECTORY and DBPROP_SSCE_TEMPFILE_MAX_SIZE? Is it possible in WinCE5 to directly put it in RAM? How big do these temp files get?
I've read of some bad experiences with autoshrink. Are there any reasons not to set DBPROP_SSCE_AUTO_SHRINK_THRESHOLD to 100 if the database will be compacted regularly?
Any other advice for the more obscure settings such as DBPROP_SSCE_FLUSH_INTERVAL or all the lock settings?
Thanks a bunch!

I designed a DTS package with eleven different connections. When I try to see the proberties of a connection the enterprise manager immediatly closes without giving me a warning. This happens only with two connections (in my example M1 and M2). This mistake has no influence to the execution of the package. In my opinion it is a fault of the DTS package desinger but may be that I made something wrong.
Is there anybody who knows this mistake? Thanks for your help.

Hi All,
I am working on a SSIS package which is using a Script task, now I have all the connection properties set up in the .NET script using connection strings, what do I need to do if I have to set this up using a config file or something else which is more secure (I dont want to leave the connection information in the script). Please Advice.
Thanks

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!

How to use variables in Connection Manager's properties? I see some replies through Configuration Package. But what if, it is still in development stage? I mean, can I use the Variable tab and create some variables like
User::DBUserNameSource, User::DBPasswordSource,
User::DBuserNameDestination, User::DBPasswordDestination,
Then put them in Password and UserName property of Connection Manager? If this is possible, how and how can I set the values of those variables I mentioned when I am going to deploy the package in the Production?

i have to store some data on a remote sever(MS SQL SERVER2000). The scenario is like 1. The web application runs on a local machine. User (who inputs) uses through LAN.2. The Input should be stored in the remote server. if the remote connection is ok. otherwise it should be saved in local server's database(MS SQL 2000).3. In the application's web.config there is a connection string pointing to the remote server and another one (alternating one) points the local server's database. in scenario like this i first to tested the remote connection. if it is not ok then i initialize the local server's connection like thisprivate MyConnection() { try { connectionSql = new SqlConnection(ConfigurationManager.ConnectionStrings["ConnForRemote"].ToString()); connectionSql.Open(); } catch (Exception ex) { connectionSql = new SqlConnection(ConfigurationManager.ConnectionStrings["ConnForLocal"].ToString()); } finally { connectionSql.Close(); } connectionSql2 = new SqlConnection(ConfigurationManager.ConnectionStrings["Temp"].ToString()); }My problem is when the remote connection is lost it takes almost 1 minute to store in local database. how can i make it more time efficient. Thanks....

Hi - hope someone can help. We're creating a ASP.NET C# site that allows a user to connect to any of our 100+ SQL Servers and query a database that sits on every server. I'm trying to work out (and failing) how we can set the 'Data Source' in a connection string dynamically using the server name selected by the user in a drop down box. Any help appreciated, thanks in advance,

Hi. I have this kind of problem since I am not very conversant with SSIS
and stripting in VB.NET.
The set-up is the following:
Flat File Source -> Script Component -> Flat File Destination
The flat file source looks like this:
NameOfFile
Headers
Data
Data
Data and many more rows of Data
NameOfAnotherFile
Headers
Data
Data
Data and many more rows
NameOfAnotherFile
Headers
Data
Data and so on in the same manner...
My stript looks like that (not very complicated):
Public Overrides Sub Input0_ProcessInputRow(ByVal Row As Input0Buffer)
Dim strRow As String = Row.Column0.Trim()
Dim strFolder As String = "Data"
Dim strConn As String
Dim charSep() As Char = {CChar(" ")}
If Mid(strRow.ToLower(), 1, 2) = "d0" Then
' This is the file name, so start a new connection to a new file
' which definitely does not exist yet
strConn = strFolder + strRow + ".csv"
' DestinationFile is the name of the
' Flat File Connection Manager
With Me.Connections.DestinationFile
.ConnectionString = strConn
End With
Else
Row.Column0 = String.Join(",", strRow.Split(charSep, StringSplitOptions.RemoveEmptyEntries))
End If
End Sub
I have several questions regarding this one.
1. Is it ok to change the ConnectionString property of the manager
to redirect the row to a different file? If not, what more to do?
2. If the new destination file does not yet exist, will it be created for me or will
I get an error? If I do, what to do not to?
3. The most important: What steps to take so that a row is discarded
from the pipeline in the script? I want some rows not to be directed
to the file destination. These are the lines that contain the name
of the file into which the data below belongs.
If you can optimize some steps in the script, then please do so by all means.
Thank you for any comments and the knowledge you kindly agree to share with me.

I have 3 web identical web apps whose only diff is that they access different SQl Server DB's. I use the SQLDataSource in a number of pages to retrieve data from the db. The apps all use Forms Auth. I would like to be able to see who is the logged on user user and assign the approp connection string to all the SQLDataSources in the app. For example when user UserA logs in they are retrieving data from on db but when UserB logs in they are retrieving data from another db.
I am sure this can be done but could use a little guidance. Thanks in advance.
