When you execute a HELP SESSION statement, the system returns 2 types of names, and where applicable, titles for database objects:
- Primary names and titles (for example User Name), according to the object definitions that exist in the data dictionary. The system substitutes error characters for any characters that are untranslatable into the session character set.
- A set of 3 additional fields associated with each name or title. For example: The 3 fields for User Name are:
- User Dictionary Name
- User SQL Name
- User UEscape
The 3 fields for a title (only for applicable objects, for example, tables and columns) are:
- Dictionary Title
- SQL Title
- Title UEscape
These fields help users to manage the differences between the data dictionary representation of name or title and the representation in the session (client) character set.
For the rules governing the content and use of name and title fields, see Teradata Vantage™ - SQL Data Definition Language Detailed Topics , B035-1184 .
