Показать описание
An index normally points to a row in a physical segment (a table). But a partitioned table consists of multiple physical segments, so the index structures and the data contained within the index need to be slightly different for partitioned tables.

Do indexes make queries on partitioned tables even faster? For example, for the index on "customer" column in this video, for which type of queries does the index become more efficient?

I want to ask something that could seems trivial, but i can't find online nothing that txplains it well. Why status for partitioned index is "N/A"? i've been able only yo find this definition "N/A indicates that index is a partitioned index, not applicable for User_indexes and dba_indexes need to view with user_ind_partitions and dba_ind_partitions." I can't really get what the part after the comma means, and also what the N/A stands for?

Hello! what happens if I add the clause "UPDATE INDEXES" even if I drop a partition with a local partitioned index? will it give me some errors?
