To access feature type format parameters, open the Feature Type Properties dialog by clicking the properties 
button on a feature type in the workspace.
These parameters apply only to a selected feature type, not to the entire writer.
Tip: If a feature type parameter listed here conflicts with a writer-level parameter, then the writer parameter will be ignored and this feature type parameter will be used.
Table Settings
Create Table
Create destination table/list if it does not exist.
Drop Existing Table
If a table already exists with this name, it should be dropped and recreated before any features are written to it.
Writer Mode
When Create Table is set to No, this parameter lets the user specify how features will be written into the destination table. Supported feature operations are:
- Insert: Append rows onto the destination table using attributes on features.
- Update: Update existing table columns using attributes on features. A selection method must be specified in the Row Selection group.
- Delete: Delete existing table rows. A selection method must be specified in the Row Selection group.
