A brief Google search led me to this article.

It's not difficult, but it's much easier (and almost certainly faster) if you can do this in T-SQL instead.

Two things on this... first, even the article that Phil cites states that it's a whole lot easier to do in T-SQL. Second, even with the technique in the article, it's still not actually being done by SSIS... it's being done by a script.

--Jeff Moden

RBAR is pronounced ree-bar and is a Modenism for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
     Stop thinking about what you want to do to a row... think, instead, of what you want to do to a column.
Although they tell us that they want it real bad, our primary goal is to ensure that we dont actually give it to them that way.
Although change is inevitable, change for the better is usually not.
Just because you can do something in PowerShell, doesnt mean you should. Wink

Well, I think we are drifting into a grey semantic area here.

SSIS natively provides the flexibility to use scripts as part of packages - they are fully integrated and not some sort of add-on or hack. In this case, the data pipeline runs through a script which processes each row in (a pre-sorted) order and uses variables to track row numbers. It's the pre-sort and row-by-row processing that slow things down, of course.

Quite true. However, it's like saying that creating a CLR to do something with T-SQL is a "T-SQL Solution". Neither the CLR nor the script you speak of are a hack but they are not a "pure" solution. In this case, it's not an SSIS solution. It's a script solution that SSIS can use. :-)

SSIS also natively provides the flexibility to use a T-SQL query in the data source that generates the same numbers (or from a staging table if the original data source can't be queried via T-sql). Same semantic grey area, no?

I'd say that that was an even greyer shade than the original :-) I wonder whether Jeff would consider the use of T-SQL within SSIS to be ' done by a script' ...

BWAAA-HAAA!!!! It certainly would NOT be an "SSIS Only" solution. :-D
