If you submit a HELP INDEX request for an unindexed table, the system 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;

The system returns the following message.

*** Empty HELP information returned.
