Data coversion or Derived column?

I have a numeric column with the following sample values in a source flat file:

240

6

48

310

55

I would like to dump them in a table (destination) as string with the length only 3 and in the following format "xxx" .

Data in the destination column will look like this after the transformation:

240

006

048

310

055

Thanks for your help!

You'll need a derived column component for that. Here's the expression

RIGHT("000" + (DT_STR, 3, 1252)[columnname], 3)

Data Conversion and Derived Column issue

Hi all of you,

I think that I've done a big mess on my work... I've got plain file which must be loaded into a sql table. Up to there no problem, I use Derived Column due to columns needed be transformed with NULL, RIGHT, LEN, and so on...

But in this last package I've done half of work using Data Conversion but I've got five columns which would need be transformed but I don't know how can I do such thing. I can't connect a Derived Column from Flat File Source task, of course, it's already data conversion...

Let me know if you need further details.

Previously I think, silly idea, that it could be unified or better, that Data Conversion task allows me make transformations...

Thanks a lot for your ideas and thoughs,

Can't you just connect the output from the Data Conversion transform to the Derived Column transform, then connect it to your destination component?

Yes, you're totally right. Everything's fine.

thanks
