2.3 Deleting Records | 
3 Deleting a DataStore DataStoreGetNumFields(), DataStoreRemoveFieldFromRecord(), DataStoreDeleteField()
To optimize storage, empty fields are not stored; thus, it is possible for a datastore to be defined with four fields but contain records with fewer than four fields.
DataStoreGetNumFields()
returns the number of fields in the current record.
DataStoreRemoveFieldFromRecord()
deletes a field from the current record. (Note that passing zero in the size parameter in
DataStoreSetField()
will also cause the field to be removed from the record.)
To delete a field from the datastore itself, call
DataStoreDeleteField()
.
