If the SELECT privilege on one or more system views is revoked or not granted to PUBLIC, you can use the HELP and COMMENT statements to obtain directory information about a particular object for which you have access.

HELP does not require long or complex queries and the results can be formatted for printing.

The COMMENT statement returns descriptive information about a database or database object. This includes information about Data Dictionary views.

For example, the following COMMENT statement:

COMMENT ON DBC.UserGrantedRightsV;

returns the following description:

The DBC.UserGrantedRightsV view provides information on access rights that the current user has granted to other users. The column names are: DatabaseName, TableName, FieldName, Grantee, AccessRight, WithGrant and AllnessFlag.
