You have the HOTEL Demo Schema for the SQL Tutorial.
Log on to the database instance DEMODB as user MONA.
Create indexes. Proceed as described in SQL Tutorial, Indexes.
You can use the system tableINDEXES to determine the following database information, among other things:
· All indexes for the table CUSTOMER and information on which indexes are not currently being used for search operations (so have status DISABLED)
SELECT indexname, disabled
FROM DOMAIN.INDEXES
WHERE tablename = 'CUSTOMER'
· All UNIQUE indexes (regardless of which of the possible SQL statements was used to create them: CREATE INDEX Statement or UNIQUE Definition)
SELECT schemaname, tablename, indexname
FROM DOMAIN.INDEXES
WHERE type = 'UNIQUE'
Columns of an index: see INDEXCOLUMNS
