I need to periodically import a (HUGE) table of data from an external data source (not SQL Server) into SQL Server, with the following scenarios: Some of the records in the external data source may not exist in SQL.Some of the records in the external data source may have a different value at different imports, but this records are identified univocally by the same primary key in the external datasource and in SQL Server.Some of the records in the external data source may be the same in SQL.
Due to the massive volume of the import, I would like to import only the records which are different from what I have in SQL Server (cases 1 and 2 above). In fact case 2 is the most critical.
I thought of making a query with a left outer join between the data in the external data source table (SOURCE) and the data in the SQL Server table (DESTIN). The join is done on the respective primary keys (composed keys of up to 10 columns) and one of the WHERE conditions will be that the value in SOURCE is different from the value in DESTIN.
The result of this query would be exactly what I need to import. How to do this in SSIS??? I couldn't figure out how to join tables in different data sources yet.
In fact I cannot write a stored procedure to do that, since one of the sources is in a datasources not SQL Server. I have seen the Lookup transformation in this article http://www.sqlis.com/default.aspx?311 but this is not exacltly what I want to do. Another possibility is to use the merge join, but due to the sorting I believe its performances would be terrible!
I've encountered a few problems using SSIS against non-SQL Server data sources and was hoping that others might have some experience. Google searches and browsing MSDN hasn't led me to a solution, so any advice on the following is appreciated:
1) When using the "Data Source Views" wizard to add a data source view from an ODBC data source, only tables appear in the object listing. Views do not. (I've also observed this with SQL Server 2005 databases as well, but it's a bigger issue when you can't use the native SqlClient, as is the case for many ODBC-only databases.) ODBC traces show that both table and view metadata is being returned to SSIS correctly, so it appears as though SSIS is filtering out views from the object listing in the wizard.
2) When creating named queries against (non-SQL Server) ODBC data sources, SSIS appears to use the SQL Server SQL syntax for referencing schemas/objects (e.g. "SELECT * FROM [schema].[table]", rather than "SELECT * FROM schema.table"). This isn't valid SQL in many databases. Am I missing something? Is there a way to change this through some configuration setting?
I am new to SSIS. I would like to know if I want to transfer data from one Oracle schema to another Oracle schema and also to do scheduling of the packages, can I still use SSIS? If yes, what are the components that need to be installed on the database server and the development environment? I hope I don't need the full SQL Server database installation in order to use SSIS.
I have a project where I am creating a test environment. My objective is to give the client staff a set of instructions to follow to make sure the test mirrors production. I have migrated the SRS databases over to the new test server. All of the reports are there as is the security but where I run into an issue is the data sources for SRS. They are all pointed at the production servers. Is there an easy way to make the change possibly using a SQL update statement or exporting all the reports to XML and doing a find and replace. The shared data sources I went through manually and changed but there were 40 data sources. Now I realized some of the reports have embedded data connections. There are hundreds of reports to go through.
I am wanting to change from using a query to move this data to using an SSIS Data Flow. I am familiar with using Merge Join to combine the two tables (H & S in this case), but I'm not sure where I can use the ISNULL in the manner described above. Is there a way to do it in the Merge Join? Do I have to do it after the Merge Join?
1. Data Warehouse 2. OLAP CUBE in Analysis Services
My question is - If my Data Warehouse is changed (Having Append Data) - My OLAP Cube will have the Append Data?
It's possible, my OLAP Cube always having Append Data if my Data Warehouse is changed? If yes, how to do it without re-deploy and re-process my Analysis Services Project....
I'm searching for a way to compare informations from one database against another database.
E.g. i want to check if serialnumbers of my first database (eg hardware.xls or hardware.csv ) are already stored in my sql server database.
I know i can use sql querys (Joins) for that task but i don't know how i can access 2 different databases at the same time. Do i need a tool for it? Does Excel is able to compare those data? But how? I'm searching for that thread since 2 days testing with some tools without any success...
I apologize for not doing the legwork to see if i can answer my own question, but I am close to a loosely planned SQL 2005 migration and don't have time and resources to test my own theories.
Is there a way for a Reporting Services 2000 server to connect to SQL server 2005 databases? I've tried creating a new data source and changing a report to this data source, but it seems like the report is still using the old data source. I'm guessing i might need to register new data providers on the 2000 RS server and then change the existsing data sources.
An SSIS package to transfer data from a DB instance on SQL Server 2005 to SQL Server 2000 is extremely slow. The package uses an OLEDB Source to OLEDB Destination for data transfer which is basically one table from sql server 2005 to sql server 2000. The job takes 5 minutes to transfer about 400 rows at night when there is very little activity on the server. During the day the job almost always times out.
On SQL Server 200 instances the job ran in minutes in the old 2000 package.
Is there an alternative to this. Tranfer Objects task does not work as there is apparently a defect according to Microsoft. Please let me know if there is any other option other than using a Execute 2000 package task or using an ActiveX Script to read records from one source and to insert them into the destination source, which I am not certain how long it might take and how viable will that be?
Can anyone shed light on why I cannot get away from named pipes in my SQL2005 Reporting Services Data Sources? Can it not just use TCP/IP? My configuration uses two servers, one in which the reportserver is setup on, and another which hosts the database that is reported against. We are trying to avoid having to open up named pipes on the server that stores the data.
Any help would be appreciated.
An error has occurred during report processing.
Cannot create a connection to data source 'wc_datasource'.
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: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
For example, the table below, has a foreign key (ManagerId) that points to EmployeeId (primary key) of the same table. -------Employees table-------- EmployeeID . . . . . . . . . . int Name . . . . . . . . . . . nvarchar(50) ManagerID . . . . . . . . . . . int
If someone gave you an ID of a manager, and asked you to get him all employee names who directly or indirectly report to this manager. How can that be achieved?
Hi My project is in .NET 2003 i.e. framework 1.1 and database in SQLServer 2000. But the reports have been developed using SQLServer 2005 Reporting Services. Now when I am trying to deploy them through deployment project of .NET its giving me following error:"Using other editions of SQL Server for report data sources and/or the report server database" is not supported in this edition of Reporting Services. Now I am really confused with this. Can any one please guide me regarding this ASAP. Thanks, Falguni
I am pretty new to SSIS. I am trying to create a package which can accept data in any of several formats. i.e. CSV, Excel, a SQL Server database/table and import the data into my destination database.
So far i've managed to get this working OK. However I am now TOTALLY stuck. I'm currently trying to just concentrate on the data sources being a CSV (using a Flat File Data Source) and/or an Excel Spreadsheet.
I can get the data in and to my destination using a UNION ALL component and mapping the data sources to it so long as both the CSV file and the Excel spreadsheet exist.
My problem is that I need my package to handle the possibility that only the CSV file might exist and there is no Excel spreadsheet. In which case i'd like the package to ignore the Excel datasource completely. Currently either of my data sources do not exist I get errors and the package terminates.
Is there any way in SSIS that I can check all my data sources to see which ones exist (i.e. are valid). If they exist I want to use them. If it doesn't exist i'd like to disgard it (without error - as long as there is a single datasource the package should run)
I've tried using the AcquireConnection method in a script task on each of my connections, hoping that it would error if the file/datasource did not exist. It doesn't though (in the case of an Excel datasource it just creates a empty excel file for me).
The only other option I can come up with are to have seperate packages depending on the type of data we want to import and then run a particular package depending on the format of the source data. This seems a bit long winded. I am pretty sure I must be able to do what I want to achieve but I can't work out how.
I'll be grateful to anyone who can send me any tips/hints/links on how I can achieve this.

Hi, i'm wondering which is the best way to search data in a SQL Server. I reach data using Data Sources and Data Views and also with OLE DB Source with a Data access mode: Named query. I have to write the data into a Flat File. So, does any one knows which is the best practice for this? Or any one of the two are good choices? Thanks for your help.
In my project i want a report. In that report data is getting from more than one data sources(systems). While creating data source view i used named query for both primary and secondary data source. But at the time of crating "Report Model" i am getting below error.
An error occurred while executing a command. Message: Invalid object name 'Table2'. Command: SELECT COUNT(*) FROM (SELECT SerialNum, ModelNum AS com_model FROM Table2) t
Is there any way to create a report with multiple data sources?
I'm wondering if SSIS will be the solution to the problem I'm working on.
Some of our customers give us an Excel sheet with data they want to insert or update in the database.
I've created a package that will take an Excel sheet, do some data conversion so the data types match up and after that I use a Slowly Changing Data component to create the insert/update commands.
This works great. If a customer adds a new row to the Excel sheet or updates an existing row changes are nicely reflected in the database.
But now I€™ve got the following problem. The column names and the order of the columns in the Excel sheet are not standard and in the future it could happen a customer doesn't even use an Excel sheet but something totally different.
Can I use SSIS for this? Is it possible to let the user set the mappings trough some sort of user interface? I€™ve looked at programmatically creating the package but I€™ve got to say that€™s quit hard to do€¦ It would be easier to write the whole thing myself than to create the package trough code ;)
If not I thought about transforming the data in code before I pass it on to the SSIS package in something like XML. That way I can use standard column names and data types.
So how should I solve this problem? Use SSIS or not?
Hi i have data on a Server in a different database which i like to access from within my ssis job.
I just need to look up information from one table on this database so i can references it. Is there a way of doing this is SSIS. Rather then me having to load the data from one database to another as the data may change.
i tried having 2 sources of data feed into a look up but that does not work..
On my home page I have several different folders to reports which require different data sources. the problem is that within these folders there are multiple copies of the same datasource. is it possible to store all of the datasources in one folder, one location? it would certainly be easier when changes to usernames and passwords need to be modified!
I searched and read about Data Sources and I'm seeing that there is no advantage in using it, which is what I found from playing around with it.
I expected that you would set a global connection in Data Sources and somehow link this to the things in your Connection Manager, giving you one place to switch from one environment to another. But reading the discussions here and playing around with it, this is not the case.
So, why is it there?
Next question.... another thing I gathered so far is something called "Configurations" that will do what I was describing above. Where do I do this?
I'm trying to combine two reports I've created into a form letter. The goal is to have a letter that indicates the students maximum UBSCT score for Math, Reading and Writing. Also in the letter we want to include the student's total number of credits awarded and overall GPA. I not sure if I need to try and combined the two queries or use two different data sources in Reporting Services. I've tried creating one sql statement but the grouping are giving me fits. I fairly new to Reporting Services.

I have referrenced System.Data.SqlServerCE.dll to my web project in order to create a .sdf file. I haven't wrote any code,just referenced it. When I build the project I get this error:
Error 2 'System.Data.SqlServerCe, Version=9.0.242.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91' cannot be loaded.
I manage to get the SSIS working. Now I would need to do these tasks.
I first want to get data from 2 different sql servers. What would be the best method to accomplish this? Both are in Sql Server 2005.
Secondly I want to make sure if any of the servers couldn't be found on the network or in any case the getting data task failed for any one of them the package won't continue and an email should be send to an email address.
Thirdly If everything is ok then I should combine both and generate one sequence no for them and save them on to another location and then generate a file with modified values.
In brief, here is my quandary… I have a GridView on a page with some radio buttons, a couple of check boxes, some drop downs etc. And depending on what the user selects the Grid View needs to show different columns from the database… The easiest way I have found to do this is to have a separate Data Object for each “view�, i.e. each variation of the checkboxes and radio buttons (which determine which dropdowns to use for the variables) and then bind the GridView to the specific Data Source at runtime…
It seemed like a good idea at the time, but now I have over 7 different data connections cluttering up the design view, and more to come and I feel like I am missing a better way to achieve the same results…
Does anyone have some advice for a major novice?
Here’s the beginning of a large set of nested ifs, if this is the way it’s done that’s fine too, I’ll just keep creating data sources, I just get the feeling there must be an easier way to do this..
I'm just wondering if it is bad programming practice to have many data sources on one page. I need a "Matrix" type of page that grabs data from many tables and so far I have 5 data sources. Is this common or is there something I should be doing to make it more efficient?
Can I import in my query a file from other sources (in this case it's a job that has elaborated server database data, but I could be in the need of using for instance Excel files or others) and compare its fields with the tables in my query?
I have a vb program that calls a sp. My vb program connects to DataSource1, Catalog1 and to DataSource2, Catalog2. My sp resides in Catalog1 using a table from catalog1 and a table from catalog2.
