SSIS Package design question

Hi,

Would you please let me know what woud you do if the followings are need to be implemented using SSIS 2008 BIDS:

1. Query a database table A
2. Loop through each A record, and query another database table B with part of A fields
3. Based on selected fields of B, set user variables accordingly.
    At the same time, loop through each B record, and query the third table C with part of A and B fields.
4. Concatenate a string with selected fields from Table A, B and C with the variables
5, Write the string to a flat file

please, if possible, illustrate the nodes that you would use. Thanks a lot.

I have tried to use 2 ways, but still not able to make them to work:

1. Data Control  with OLEDB Source for A table --> OLEDB Comand for B --> Script Component

with this way, OLEDB Command for B is not able to produce outputs. Therefore, I am not able to set variables in side script based on the selected B records.

2. Using Control flow -->Execute SQL Task for A --> Foreach Loop for resultset of A --> contains another Execute SQL Task for B --> still inside the foreach container, using Script Task

With this way, I can have outputs of precedent nodes however, I am not able to referent any resultsets in side the script.

Hope you understand what my problems are.

Thanks,

Hi.

Pretty tricky.  Could this be done using pure SQL code and creating a view perhaps?  Maybe using some temp tables?  Probably a better knowledge of how tables A, B, and C work with each other would help.  Thanks.
