dataflow - SSIS - How do I join two sources on a complex expression? -

-

i have 1 data source has column part_number.

my second data source has product_family_id, product_id , part_mask.

mask pattern string used in expression part_number mask. instance 'nxa%' or '001-[abcd][456]9-121%'

usually legitimate part numbers product family based on available product part masks, in instance need go in other direction. based on part number, must find related products in product family , store in summary table.

simulating in t-sql:

declare @partlist table (partnumber varchar(100))  insert @partlist (partnumber) values ('nxampvg1')  select distinct pl.partnumber, match.product_id @partlist pl join (  select m.masks, p.product_id  mcs_productfamily_partmasks m     join product p on m.productfamilyid = p.productfamily_id) match     on pl.partnumber match.masks

desired output:

part_number product_id ----------- ---------- nxampvg1    15629 nxampvg1    15631 nxampvg1    15632 nxampvg1    15633 nxampvg1    15634 nxampvg1    15635 nxampvg1    15636 nxampvg1    15637 nxampvg1    15638 nxampvg1    15639

how can accomplish in ssis data flow task?

create 2 data sources, 1 gets part numbers source 1 , gets product id's, product family's , masks using inner query select m.masks, p.product_id mcs_productfamily_partmasks m join product p on m.productfamilyid = p.productfamily_id source two. data destinations these should staging tables on same sql server. use derivation of sql stated in example in such way: select distinct pl.partnumber, match.product_id stg_source_one pl join stg_source_two match on pl.partnumber match.masks
