In addition to the connectivity information required for a file
upload (Database URL, Driver Identifier, Driver Class, User ID, and
Password, all described in the previous sections), you also need to
provide information about the particular file upload operation. This
information includes:
- The name of the table in the host database that you want to modify.
- The name of the local file containing the data that you want to
add to the table in the host database.
- The type of file upload that you want to perform: create, replace,
append, or update.
Also, for two types of file upload, you have to specify additional
information: a Field Description Table for a create operation and
Key Columns for an update operation.
