HELP HASH INDEX is considered obsolete. Although HELP HASH INDEX is still supported for the current Teradata Database release, Teradata recommends that you instead use the DBC.IndicesV[X] views. For information, see Teradata Vantage™ - Data Dictionary, B035-1092.
The system does not return the Dictionary Name, SQL Name and Uescape attributes, which are returned for other HELP statements.
