The command in Listing 1 creates a FOT index on tab_1 table on col1 with 1000 buckets (subtrees).

Drop the FOT index using the following command.
使用以下命令停止fot。
A FOT index is an index that is similar to a B-Tree index, but an FOT index has multiple root nodes and fewer levels. (B-Tree indexes have only one root node and more levels.)
