Prerequisites

You have the HOTEL Demo Schema for the SQL Tutorial.

Log on to the database instance DEMODB as user MONA.

Define synonyms. To do this, use the CREATE SYNONYM Statement (create_synonym_statement).

Examples

You can use the system tableSYNONYMS to determine the following database information, among other things:

·        The table (basis table, view table) for which the PUBLIC synonym SHORT_TAB was defined

SELECT tableowner, tablename
  FROM DOMAIN.SYNONYMS
    WHERE public = 'YES'
      AND synonymname = 'SHORT_TAB'

·        Private synonym for the CITY table of the user MONA

SELECT synonymname
  FROM DOMAIN.SYNONYMS
    WHERE tableschemaname = 'HOTEL'
      AND tableowner = 'MONA'
      AND tablename = 'CITY'

Note

Existence of a synonym: see TABLES
