31
i have a column ID and something like 1000 items, some of then were removed like id=90, id=127, id=326
how can i make a query to look for those available ids, so i can reuse then for another item?
its like a min(ID) but i want to find only the ids that are NOT in my database, so if i remove a item with the ID = 90, next time i click on ADD ITEM i would insert it as id = 90
