Hi,
How about the steps in details to build the project doing these, using Biztalk 2009?
1) retrieve the records from the table and then point to the physical file in the server machine using the filename column we have retrieved, i.e. the filename column will hold such value 'c:\proj1\out\ff1.txt'
2) fetch the data of such input file into one other table of the same DB
Many Thanks & Best Regards, Hua Min
