I use the following statement to export records from db2 tables:

EXPORT TO file_name OF file_type
LOBS TO lobfile_directory_1, lobfile_directory_2, ...
LOBFILE lobfilename
MODIFIED BY LOBSINFILE
select_statement

I have two questions:
1. How will DB2 store blob fields in the lobfiles? one blob field in one lobfile or many blob fields in one lobfile?
2. If I use parameter "LOBS TO lobfile_directory_1, lobfile_directory_2", how will the lobfiles be stored in these two folders?

Thanks a lot.
