Both reserved words and keywords have special meaning in PL/SQL. The difference between reserved words and keywords is that you cannot use reserved words as identifiers. You can use keywords as as identifiers, but it is not recommended.
Table D-1 lists the PL/SQL reserved words.
Table D-2 lists the PL/SQL keywords.
Some of the words in this appendix are also reserved by SQL. You can display them with the dynamic performance view V$RESERVED_WORDS, which is described in Oracle Database Reference.
