Purpose

Displays the attributes for the primary and secondary indexes defined for a base data table, hash index, or join index.

Because hash indexes cannot have secondary indexes, a HELP INDEX request run against a hash index reports the attributes of its primary index only.

HELP INDEX does not display the attributes for hash or join indexes. See “HELP HASH INDEX” and “HELP JOIN INDEX” for information about how to report the attributes for hash and join indexes, respectively.

Privileges

You must either own the table or join index on which the index is defined or have at least one privilege on that table, hash index, or join index.

The SHOW privilege enables a user to perform HELP or SHOW requests only against a specified index.
