Table Settings: General
Table Handling
This parameter controls how the feature type handles destination tables. These options are available:
- Create If Needed: Create destination table if it does not exist. The writer uses the information within the FME workspace to automatically create Vector Feature tables as required. All tables will be created when the first input feature is processed. If no features are sent to a feature type, then the corresponding table will not be created.
- Drop and Create: Drop destination table if it exists, then create it. The writer will drop and re-create the table before writing any features to it. Tables will be overwritten when the first input feature is processed. If no features are sent to a feature type, then the corresponding table will not be overwritten.
