Extra column to be added while importing data from flat file to SQL Server

Question

I have 3 flat files with only one column in a table.
The file names are bars, mounds & mini-bars.
Table 'prd_type' has columns 'typeid' & 'typename' where typeid is auto-incremented and typename is bars, mounds & mini-bars.
I Import data from 3 files to prd_details table. This table has columns 'pid', 'typeid' & 'pname' where pid is auto-incremented and pname is mapped to flat files and get info from them, now i wanted the typeid info to be received from prd_type table.
Can someone please suggest me on this?

Answer 1

You can get it as follows
Assuming you've three separate data flow tasks for three files you can do this
1. Add a new column to pipeline using derived column transformation and hardcode it to bars, mounds or mini-bars depending on the source
2. Add a look task based on prd_type table. use query as
SELECT typeid,typename
FROM prd_type
Use full cache option
Add lookup based on derived column. new column -> prd_type.typename relationship. Select typeid as output column
3. In the final OLEDB destination task map the typeid column to tables typeid column.
In case you use single data flow task you need to include a logic based on filename or something to get the hardcoded type value as bars, mounds or mini-bars in the data pipeline
