Can A Column Be Derived Using Substring But The Parameters Are A Result Of A Select Statement?

I have a table which has a field called Org. This field can be segmented from one to five segments based on a user defined delimiter and user defined segment length. Another table contains one row of data with the user defined delimiter and the start and length of each segment. e.g.









Table 1

Org

aaa:aaa:aa

aaa:aaa:ab

aaa:aab:aa








Table 2














delim

Seg1Start

Seg1Len

Seg2Start

Seg2Len

Seg3Start

Seg3Len


:

1

3

5

3

9

2



My objective is to use SSIS and derive three columns from the one column in Table 1 based on the positions defined in Table 2. Table 2 is a single row table. I thought perhaps I could use the substring function and nest the select statement in place of the parameters in the derived column data flow. I don't seem to be able to get this to work.



Any ideas? Can this be done in SSIS?



I'd really appreciate any insight that anyone might have.
