metadata driven SSIS package--table variable

Is there anyone know if a simple SSIS package (moving data from source table to target table) or task can be called repeatedly using a variable that obtains value once a time from a metadata table containing only table names. Basically, I would like to pass in a table variable to the SSIS package or task to start the ETL for different tables. Thanks a lot!

Hmm,

I suppose you could do it that way. I am currently generating complete SSIS packages from metadata. No variables. Explicit references. You would still need to handle the objects of the package that change, like columns datatypes, etc...|||You cannot have 1 data-flow that is used for different tables (unless the structure of each table is exactly the same - which I doubt).

You will need multiple data-flows, one for each table.

Once you have your multiple data-flows, decide which one of them to execute using workflow expressions. Allan and Darren have a good example of this here: http://www.sqlis.com/default.aspx?306

Do you think you could post a simple example of what you are doing? I think there are a lot of people in the SSIS community who are realizing they need to head toward dynamic package creation in order to achieve the maintainability that they were able to with DTS and ActiveX scripts.

Thanks,

We would like to creat a SSIS package for one table,and all the other tables to be constructed based on the table name retrieved from a metadata table that contains all the table names. Thanks!

"More or less the same" isn't enough. They have to be exactly the same for them to be able to use the same data-flow.

Can we create a SSIS package using VB .NET? If we can, we can call metadata driven stored procedure to build the transformation task specifically for each table.

Could you give more detail as how you generate the metadata driven SSIS packages? THanks

One of the samples provided with the product shows how to build a package progamatically (although I've just looked at my Junne CTP installation and can't find it - perhaps its been removed?). Once you have mastered how to do that you could work on building them based on metadata. I haven't seen any examples of doing that - perhaps you'd be the first person to do it?

-Jamie|||Patrick,

DO you have sample code? Thanks!|||Patrick,

Can you give some rough ideas as what you are using in terms of programming languages, scripts or SSIS tasks to create metadata driven SSIS packages.

Many thanks!
