If the column for which information is requested defines a single-column index, then that is reported along with the uniqueness and type of index. HELP COLUMN returns index information for single-column indexes only. For multiple-column indexes, the columns are reported as not being used in an index.

HELP COLUMN does not provide information about whether a column is used in the partitioning expression of a partitioned primary index. Use SHOW TABLE (see SHOW object) or the system view DBC.IndexConstraintsV (see Teradata Vantage™ - Data Dictionary, B035-1092 for further information) to obtain the partitioning information.

HELP COLUMN returns the information indicated in HELP COLUMN Information and Attributes.
