... Horizontal ellipsis points indicate either:
  • That we have omitted parts of the code that are not directly related to the example

  • That you can repeat a portion of the code

CREATE TABLE ... AS subquery;

SELECT col1, col2, ... , coln FROM employees;




Vertical ellipsis points indicate that we have omitted several lines of code not directly related to the example.
Bold Bold typeface indicates terms that are defined in the text or terms that appear in a glossary, or both. When you specify this clause, you create an index-organized table.
UPPERCASE monospace (fixed-width font) Uppercase monospace typeface indicates elements supplied by the system. You can back up the database by using the BACKUP command.


lowercase monospace (fixed-width font) Lowercase monospace typeface indicates executables, filenames, directory names, and sample user-supplied elements. Enter sqlplus to open SQL*Plus.

Back up the datafiles and control files in the /disk1/oracle/dbs directory.

The department_id, department_name, and location_id columns are in the hr.departments table.

lowercase monospace (fixed-width font) italic Lowercase monospace italic font represents placeholders or variables. You can specify the parallel_clause.

Run Uold_release.SQL where old_release refers to the release you installed prior to upgrading.

MixedCase monospace (fixed-width font) Mixed-case monospace typeface indicates a Data Guard broker database property. The mixed case helps you visually differentiate a Data Guard broker property from other system-supplied elements, which are always shown in uppercase typeface.

Mixed-case monospace typeface can also indicate other programmatic elements. Enter these elements as shown.

The StandbyFileManagement property corresponds to the STANDBY_FILE_MANAGEMENT initialization parameter.

The JRepUtil class implements these methods.
