If the table does not exist it will automatically be created with the fields defined under the Tags properties.
If the table does exist each field will be verified to match data type and field name. Fields that do not exist in the table will be created. Fields that do exist and their data type does not match the data type defined will be converted to the defined data type.
When this option is disabled no attempt will be made to create the table or fields and the table must already exist with the correct field names and types.
