ms access - Can Autoincrement field ever use the same value twice? -


i have table1 id field, type autoincrement. need copy entire record table1 table2 if there no record same id in table2. delete record table1.

i need know if table1 gets new records, id field never number ever used before. happen automatically, or need ensure this?

i tried deleting records , adding new ones, , didn't use same id, i'm not sure happens.

it so, auto-increment fields in ms access incremental, if records deleted, database compacted, etc. proposed number can reset deleting auto-increment field, perform copy of table , adding auto-increment field again.
