 Appends to an existing table
 Simple settings for:
 Drop Table or
 Truncate Table

3. Writing to Databases - Updating/Deleting
 Updating/Deleting existing data isn’t so easy
 Requires multiple parameter settings
 Uses format attributes and writer ‘modes’
 Might involve multiple transformers
 Can take some effort to get working
 Prerequisites to incremental updates…
 You need to know which features to
insert / update / delete !

4. New Transformers

 Features enter the transformer and it updates
existing features
 DatabaseDeleter
 Feature(s) enter the transformer and it deletes
existing features.

6. Parameters
 Attributes to Join on
 Where clause option
 Columns to Update

7. Pros
 Very easy to configure
 Great for relatively simple updates:
 a few feature types
 a small number of fields
 Great for deleting based on an attribute value

8. Cautions
 No Geodatabase support
 No Transactioning or Commit/Rollback handling
 Not so useful for updating lots of attributes
 Not appropriate for Dynamic Workflows

9. Other Approaches
 Use feature based updates
 fme_db_operation
 fme_where
