Advantage Of Using A Data Source In A Project
Jun 18, 2007
I am new to SSIS.
I came across the following article:
http://technet.microsoft.com/en-us/library/ms139848(SQL.90).aspx
It states that:
"A data source can be defined one time and then referenced by connection managers in multiple packages. You use a data source object in a package by adding a connection manager that references the data source object to the package. There is no dependency between a data source and the connection managers that reference it."
I have created a data source (DS1) and set it to point to a database say DB1. In the connection managers area, I create a connection manager CM1 using the datasource DS1.Now I edit DS1 to point to a different database DB2. When I open CM1 however it€™s still pointing to DS1.
I guess this is because it€™s said that there is no dependency between the connection manager and data source. My question is what exactly is the advantage of using a data source?

Hello,
I've created a Report Model Project that can be used by Report Builder to generate ad-hoc reports. I'm trying to create a connection string in my Report Server Project that points to the Report Model Project data source view.
All I can do is create a regular datasource, which bypasses the metadata contained in the Data Source View.
Basically I want my Report Server Project and my Report Builder reports to leverage the same metadata. Is this possible? If so how do I get the connection string?
Thanks!!

I have an existing project with the data source and report folder with working reports. I need to create a model for other department members to use Report Builder, not Business Intelligence Developer Studio, to develop their reports from. How do I add a data source view and report model folder to the project so I can then create a view and model?

Our team has the following problem:
I create a SSIS project in VS and add it to Team Source Control. When the project and all it's files exist on a machine and I want to open the project from Source Control, everithing works fine, but when another developer, who doesn't have the files on his machine, wants to open the project from Source Control he is required to check out the project file.
I've investigated the problem and found out that each project has a database file (with .database extension) and project file contains a reference to it. Once the user opens from Team Source Control a project that isn't presented on a target machine, the VS creates a new database file on a local machine and insists to change the reference in the project file.
Does anyone have a workaround for the problem?
Thanks

For some reason in a Team Foundation Team Project that has multiple project types (SSRS, SSIS, WebSite, C# Business DLL...), the SSIS project makes itself the startup project to the team project. If I explicitly set another project as the startup project to the team project and then select an SSIS package in the SSIS project in the team project, the SSIS project becomes the startup project automatically.
I am using Visual Studio 2005 SP1.

Hi
In this code how can I create a new data source and new data source view and model and structure that it run dynamic.
In this code I have a lot of errors, that they are about server and database don€™t have in current code,
In this code, first I should definition server or no?
Database dbNew = new Database (databaseName,
Utils.GetSyntacticallyValidID(databaseName, typeof(Database)));
srv.Databases.Add(dbNew);
dbNew.Update(true);
***********************************************************
How can I create data source and data source view and model and structure?
Please say code of that, and guide me.
databasename and srv is unknown.
Do I add other reference with analysis services?
Please explain about these codes:
************************************************************************
1)
RelationalDataSource dsNew = new RelationalDataSource(
datasourceName,
Utils.GetSyntacticallyValidID(
datasourceName,
typeof(RelationalDataSource)));
db.DataSources.Add(dsNew);
dsNew.ConnectionString = connectionString;
dsNew.Update();
2)
RelationalDataSourceView rdsv;
rdsv = db.DataSourceViews.Add(
datasourceviewName,
Utils.GetSyntacticallyValidID(
datasourceviewName,
typeof(RelationalDataSourceView)));
rdsv.DataSourceID = ds.ID
***************************************************************
3)
OleDbConnection cn = new OleDbConnection(ds.ConnectionString);
OleDbCommand cmd = new OleDbCommand(
"SELECT * FROM [" + tableName + "] WHERE 0=1", cn);
OleDbDataAdapter ad = new OleDbDataAdapter(cmd);
DataSet dss = new DataSet();
ad.FillSchema(dss, SchemaType.Source);
*************************************************************
4)
// Make sure we have the name we thought
dss.Tables[0].TableName = tableName;
// Clone here - the original DataTable already belongs to a DataSet
rdsv.Schema.Tables.Add(dss.Tables[tableName].Clone());
rdsv.Update();
5)
MiningStructure ms = db.MiningStructures.Add(miningstructureName, Utils.GetSyntacticallyValidID(miningstructureName,
typeof(MiningStructure)));
ms.Source = new DataSourceViewBinding(dsv.ID);
ms.CaseTableName = "Customer";
Add columns:
ScalarMiningStructureColumn smsc;
// From table "Customer" we will add a couple of columns
// CustomerID - key
smsc = new ScalarMiningStructureColumn("Customer ID",
Utils.GetSyntacticallyValidID("Customer ID", typeof(ScalarMiningStructureColumn)));
smsc.IsKey = true;
smsc.Content = "Key";
smsc.KeyColumns.Add("Customer", "customer_id", OleDbType.Integer);
ms.Columns.Add(smsc);
*******************************************
6)
MiningModel mm = ms.MiningModels.Add(miningmodelName,
Utils.GetSyntacticallyValidID(miningmodelName,
typeof(MiningModel)));
mm.Algorithm = "Microsoft_Decision_Trees";
mm.Parameters.Add("COMPLEXITY_PENALTY", 0.3);
MiningModelColumn mc = new MiningModelColumn("Customer ID",
Utils.GetSyntacticallyValidID("CustomerID",
typeof(MiningModelColumn)));
mc.SourceColumnID = ms.Columns["Customer ID"].ID;
mc.Usage = "Key";
mm.Columns.Add(mc);
mm.Update();
Please exactly say, whatever I want
Thanks a lot for your answer
Please don€™t move this question because I don€™t know where I should write this.

I have set up a new connection as a connection from data source, but I cannot see how to use this connection to create my Data Flow Source. I have tried using an OLE DB connection, but this is painfully slow! The process of loading 10,000 rows takes 14 - 15 minutes. The same process in Access using SQL on a linked table via DSN takes 45 seconds.
Have I missed something in my set up of the OLE DB source / connection? Will a DSN source be faster?
Thanks in advance

Today I was making a few reports.
When I tested the reports in Visual Studio, they worked great: I got the expected result.
But when I deployed the reports to our reportserver the problem started.
When I click on the directory in which my reports are deployed, I got my 4 reports.
Till now everything worked correct.
But when I click on a report to view the results it went wrong.
I got an error:
"Cannot create a connection to data source 'Live'"
(Live is the name of our data source).
We are using the Windows Logons and I am sure that I have all the rights on the server, I gave myself 'sysadmin' rights, so it should work.
I also have tried it with all the roles assigned on my account, but then it still won't work.
When I modify the data source, and set it to another server en database it works.
The datasource 'Live' exists on a x64 MsSQL server, en the other datasource is on a x86 MsSQL server.
Maybe that is the problem?
Can someone tell me what is wrong?

I was trying to load data using SSIS, Data Flow Task, OLE DB Source, source was a view to a OLE DB Destination (SQL Server). This view returns 420,591 rows from Query Analyzer in 21 seconds. Row length is 925. When I try to executed the Data Flow Task from SSIS, I had to stop the process after 30 minutes, because only 2,000 rows had been retrieved. I modified the view to retun top 440, 000 and reran. This time all 420, 591 rows were retrieved and written in 22 seconds. Next, I tried to use a TOP 100 Percent. Again, only 2,000 rows were return after 30 minutes. TempDB is on a separate SAN Raid group with 200 gig free, Databases on a separate drive with 200 gig free. Server has 13 gig of memory and no other processes were executing.
The only way I could populate the table was by using an Execute SQL Task and hard code an Insert into table selecting data from the view (35 seconds) from SSIS.
Have anyone else experience this or a similar issue? Anyone have a solutionexplanation?

When I import data I first import it from a text file into a table ofit's own, then using some logic insert some of the records into apermanent table.I am considering having the table that the data from the text file isplaced in being there all the time and just clearing it out after I dothe import, or creating it and after using it then drop it, or using atemporary table.What are the advantages of a temporary table as opposed to creating aregular table and dropping it after use?

On 64 bit SSIS platforms (win2k3 and vista), where the amount of virtual memory is practically unlimited, is there any advantage to running child Integration Services Execute Package Tasks out of process? The question pertains to 64 bit processes on a 64 platform, not 32 on 32, or 32 bit emulation processes on 64.
Would the answer be different based on the amount of physical memory on the machine, supposing one had a "reasonable" amount of memory on the machine (e.g. 4Gb or more )

Hi,
I have been working on some SSIS packages for a while now and today while i was working i was trying to create a new connection and in the process there was an error and it said the BIDS has to be closed and i closed it but later when i open BIDS and try to open my project(.sln) from the file menu to work on the half done package it pops up an error which shows the path to my project location on the first line and next statement on the pop up error box says:
"Make Sure the application for the project type (.dtproj) is installed."
I tried to check some forums in which some suggested to try installing SP1 which i tried but ..i dont know why but the SP1 fails to install (i dont know if its causing problem becoz i already installed SP2 as i had some other problem before for which the cure was to install SP2).
Did anyone here face such a problem before ?
I'd really appreciate if the experts here can tell a cure for this problem.
thanks,
Ravi

I have a Visual Studio 2005 solution which contains a Sql Server Integration Services (SSIS) project.
In this solution I have explicitly set a Web application project as startup project, but whenever I edit a DTS package within the SSIS project, VS automatically sets the SSIS project as startup project and the package I edit as startup object.
Needless to say, this may cause some really unwanted incidents when running the solution - thinking that you're about to run the Web application project (that was explicitly set as startup project), but instead, you run the edited package in the SSIS project.
Is there any way to avoid having the SSIS project automatically setting itself as startup project, any workaround here at all? :)
Thanks.

I have a very small project written in VB.Net 2005 using the SQL Server 2005 SSiS DTSx package.
I took a SQL Server 2000 dts package and using the SQL Server 3005 legacy tools migrated it so I could still use the package withing SQL 2005 until I can build one using BI/SSIS.
Anyway,I added the reference Microsoft.SqlServer.ManagedDTS so I could then use the Microsoft.SqlServer.Dts.Runtime so I can execute the commands:
Dim oApp As New Application
Dim oPkg As New Package
oPkg = oApp.LoadPackage(g_DTSx_Directory & "AOC copy Generic1 CSV to AOC_verify_file_1.dtsx", Nothing)
Dim oResults As DTSExecResult
oResults = oPkg.Execute
Ok. That works fine. Executes without a hitch. So now I try and create a setup project for this and I use the setup wizard.
During the creation of the setup project I get a message that states:
The following files may have dependencies that cannot be determined automatically. Please confirm that all dependencies have been added to the project.
C:windowssystem32msxml6.dll
OK. The dll is part of the reference I mentioned above and I have no idea what other dependencies it may have.
How do I find this out?
Has anyone else created a project like this and experenced the same?
I am on a clean build running WinXP Pro with SP2 - VS2005 with SP1 and the SQL Server 2005 tools.

I've got an SSIS solution file with project deployment model in VS 2013 and would like to deploy that to SSISDB on different environments.All these days I followed the regular way to create a project in SSISDB and deploy it to that. Now want to find out if i can automate this process and so got some questionsÂ
1. Can we automate the process of creating a project on SSISDB based on our SSIS project name? This will be like when we do a deployment it should check if the project exists or not on SSISDB based on our SSIS project name, if the project exists we just deploy the packages in the project and if the project does not exists in SSISDB it will create that project and deploy the packages.
2. Can we also automate the process of creating environments? In traditional way we manually create the environment variables under environment tab of SSISDB, but can we make that also as part of deployment? Like when we are releasing to Dev server we look if that particular Dev variable exists on that server, if it exists we just update the existing stuff and if it does not exists we just create it.
