1) Whether the index property of an entity automatically creates an index of that property as data is entered and its Index is not required for entry ??
2) If an entry is removed from the middle, for example with index 3. Then the new index will be 0 1 2 4 5 6. Or it will update itself for 0 1 2 3 4 5 ... ??
3) How to delete a single entry to say .. Line ID3 ??
4) How to edit the existing entry on any ID ??
Thnx in advance; )
1) Indexing is automatically controlled by core data. You do not do anything with it
2) Do not care, because the core data handles it.
3) Core data is not a wrapper for SQL and does not relate to tables and rows. Core uses data objects when you delete an object core data, then remove it from the store. are given.
4) You edit the data by editing the properties of a specific managed object.
The core data is not SQL Organizations are not table Object lines are not column attributes Core data is an object graph management system that can not release or release an object graph and to do so Behind SQL can not be used or may be or may be. By trying to think about core data in SQL words, you will have to completely understand the core data completely and as a result there will be very sad and wasted time.
