Connection Nonexistent At Runtime
Aug 1, 2007
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 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?

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!

I have code that runs suser_sid and if it is null it creates a login, then uses sp_adduser to add that login to the database. If suser_sid is not null then it just runs sp_adduser.
Well, suser_sid(N'COMMERCIAL DIRECT') returns a value, even though there is no login named COMMERCIAL DIRECT. Then when sp_adduser tries to run, I get an error "is not a valid login or you do not have permission".
I was able to create the login manually using a SQL query, then dropped it. suser_sid STILL returns a value for that login.
What is going on here? Why does SQL Server return a sid for a login that does not exist?
And no, I can't just modify the code - it's not my code, it's an app I'm implementing.

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

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!

Sara

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.

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

Hi,
I am having a Data flow task in For each loop which will gets 100 sourcetable names and 100 target table names...
am having a simpleData flow task which trasferes from OLEDBSource to OLEDBDestination.
I am repeating the Dataflow task which transfers from sourcetablename extracted from for loop to a destination table var.
The problem am gettting is for the first table it is able to transfer correcly because I did mapping for those tables at design time...but for the next coming sourcetable-desttable (which r having different no of cols,datatypes) its giving Validation failed...and...needs to refresh metadata....
is there any way to refresh the metadata of Data flow task (I set the property of OLEDBSource validate external meta to false then also same error is coming)
Thanks

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?

Hello. I am trying to write a VB.net application to call our SSIS packages. I have seen several tutorials, including this one:
http://msdn2.microsoft.com/en-us/library/ms190901.aspx
Which calls for me to import:
Microsoft.SqlServer.Dts.Runtime
However, I don't have this DST Runtime DLL installed on my machine. I have installed "everything" in SQL Server Developer Edition and Visual Studio. Any idea how I can get this?
Thanks,

I just ran a testbed of 4 types of SQL queries:1. inline SQL with a StringBuilder2. managed sql3. SQL text processing (@SQL as varchar(5000); SET @SQL = 'SELECT ' + @var...)4. a regular sproc that has the columns and table name hard coded1,2, and 4 always end up at about the same time given the averages.3 is always at last 1.5 times slower, and usually closed to 2 times.1 and 2 both use StringBuilders, the code is a direct copy, and 3 is a copy as well.My managed SQL is: [Microsoft.SqlServer.Server.SqlProcedure] public static void usp_Items_Select_Managed(SqlString table, SqlString name, SqlString value) { // sql StringBuilder stringBuilder = new StringBuilder(); stringBuilder.AppendFormat( "SELECT {0}.* FROM {0} WHERE {0}.{1} = {2}", table, col, value ); SqlConnection sqlConnection = new SqlConnection("context connection=true"); SqlCommand sqlCommand = new SqlCommand(stringBuilder.ToString(), sqlConnection); sqlConnection.Open(); SqlContext.Pipe.Send(sqlCommand.ExecuteReader()); sqlConnection.Close(); }Is there anything wrong with my Managed SQL, or is this just the way that it is?Thanks

I'm running a package on SQL Server 7, SP2 created in the same environment.
When running a package from DTS Designer, I get an execution status of "Error Occurred" in the Package Execution Status dialog on one of the data pump tasks I'm running along with the number of rows inserted. When I double-click on the task, I get the following message: " The Connection is currently being used by a task. The connection cannot be closed or reused".
Both the exception log for the task and the package, specified for error output, indicate the task ran successfully and the clients confirm that the appropriate number of rows have been inserted in the table. Has anyone encountered this error that can explain the cause/cure?

Hi Everyone,
I've an DTS package, which has an Execute SQL Task. I'm doing the operations based on a parameter. I need to pass that in runtime. Is there any way to do that in Execute SQL Task? BOL says that the runtime parameter can be set by giving a question mark(?). But when I tried this, it says, value not passed.
Thanks in advance.

Hi.
I posted similar stuff in one of my previous topic. what i need to do is parse database name runtime
means sample example is
USE <%1>
GO
SELECT * FROM Table_Name
here instead of <%1> i need to pass Test DB name
USE Test
GO
SELECT * FROM Table_Name
my .sql file contains <%1> so i need to replace it
i tried like
declare @t varchar(50)
declare @chg22 varchar(500)
set @t = 'Test'
set @chg22 = 'USE <%1> GO'
set @chg22 = REPLACE(@chg22,'<%1>',@t)
exec(@chg22)
SELECT * FROM Table_Name
but i am not getting it..in above example i am just took one line select * from table_name but actually in .sql file more that 300 lines are there so i m not able to concatenate it..

We run a regular query through Excel that is linked to a Microsoft SQL Server data source.
We have run this query routinely for the past few years. Suddenly this query has started returning an error message - “[Microsoft][ODBC SQL Server Driver] [SQL Server] Difference of two datetime columns caused overflow at runtime�. It seems to be a common error (as per Google search) however I don’t want to go messing around with something I don’t fully understand. Can anyone point me in the direction of what to look out for?

Hi,
Currently im using SQL queries in combination with ASP.NET..
I have currently only one table('Requests'), which has all the user info of name,id,studyrequested etc.. A person can request for any number of studies.
Now the prob is that from now on whenever a user requests for a new study not only should his details be stored in the Request table but also in a new Users table. In the Users table that particular users details must only be loaded once.. i.e. if the same user enrolls for another study his details should only be updated in the requests table and not in the Users table, since his details have already been loaded once in the Users Table..
While this works fine for new users, but what bout the old users already stored in the Requests table before the Users table existed.
Is there any way i could run a sql script only once at runtime, so that all the old legacy users are loaded once in to the Users Table.
Thanks,
Nitin

I want to combine a bunch of reports (which are stand alone reports on there own) as subreports in a parent or master report. We have done this in Crystal Reprots in order to get a group of reports out in one file.
The issue with Reporting Services is the header and footers of the subreports are not rendered, so I have to repeat the logo information for each subreport in the body of the parent report. I can do this in a table or list or rectangle, but I have to do this for each subreport. Is there any way that I can specify the name of the subreport at runtime? That way I can put everything into a List and drive it from the database. I noticed that the dropdown to select the report name does not allow you to create an expression for this field.
