COMMENT ON SEQUENCE

Adds, revises, or removes a comment on a sequence. Each object can have one comment. Comments are stored in the system table COMMENTS.

Syntax

COMMENT ON SEQUENCE [[database.]schema.]sequence IS { 'comment' | NULL }

`[database.]schema`	Specifies a schema, by default `public`. If schema is any schema other than `public`, you must supply the schema name. For example: myschema.thisDbObject If you specify a database, it must be the current database.
`sequence`	The name of the sequence associated with the comment.
`comment`	Specifies the text of the comment to add. If a comment already exists for this sequence, this comment overwrites the previous one. Comments can be up to 8192 characters in length. If a comment exceeds that limitation, Vertica truncates the comment and alerts the user with a message. You can enclose a blank value within single quotes to remove an existing comment.
`NULL`	Removes an existing comment.
