The words listed in this appendix are reserved by PL/SQL. You should not use them to name program objects such as constants, variables, cursors, schema objects such as columns, tables, or indexes.
These words reserved by PL/SQL are classified as keywords or reserved words. See Table D-1 and Table D-2. Reserved words can never be used as identifiers. Keywords can be used as identifiers, but this is not recommended.
Some of these words are also reserved by SQL. For a list of the Oracle database reserved words, see Oracle Database SQL Reference. You can generate a list of all keywords and reserved words with the V$RESERVED_WORDS view, described in Oracle Database Reference.
Table D-1 lists the PL/SQL reserved words.
