If you submit a HELP INDEX request for an unindexed table, Teradata Database returns a message explaining that there is no help information to be returned.

For example, suppose you define the following table.

     CREATE TABLE t1 (
       a INTEGER
       b INTEGER)
     NO PRIMARY INDEX;

You then submit the following HELP INDEX request on t1.

     HELP INDEX t1;

Teradata Database returns the following message.

     *** Empty HELP information returned.
